Internet safety and facts



August 2009
Fact: 86 % of the girls polled said they could chat online without their parents' knowledge, 57% could read their parents email, and 54% could conduct a cyber relationship (Girl Scout Research Institute 2002)


Tip:  Parents need to discuss internet safety with their children, indicating possible hazards. 



June 2009
Fact:  Identity theft occurs when someone uses your personal information such as your name, Social Security number, credit card number or other identifying information, without your permission, to commit fraud or other crimes.(consumerreporting.org)   

Tip:  Don't give out any financial information, such as checking account and credit card numbers; and especially your social Security number; on the phone or online, unless you initiate the call and know the person or organization you're dealing with. Don't give that information to any stranger. In general, it is only required for medical providers, banks, mortgages and credit card companies. (consumerreporting.org)
May 2009

Fact:   Many crimes that are committed in the real world also occur on the Net. These include fraud and embezzlement, harassment, "stealing" an identity, or stalking. A lot of information is available about you on the Net, and an enterprising criminal can find out a lot about you and use this information to his/her disadvantage. A criminal could use basic information about you (discovered on the Net), and then engage in "social engineering"--contacting your friends, co-workers, relatives, etc.--to learn even more.(Cyberstalking and Internet Safety FAQ by Rachel R. Hartman)
Tip:  Be VERY careful to whom you give personal information and where you post information. Use a "nonsense" password that has no relation to you as a person; use a combination of numbers, symbols, and letters and make sure it is at least 6 characters long. Change your password frequently and NEVER give it out. Try not to keep it written down. Avoid using the same password for multiple accounts.(Cyberstalking and Internet Safety FAQ by Rachel R. Hartman)



April 2009
Fact:  Four percent of children received aggressive solicitations from adultswho attempted to meet the children in person, compared to 3 percent in 2000.(Love to Know website:  2007 Internet Safety Statistics for Children)
Tip:  Discuss Internet safety with your children, starting when they are very young so they learn how to identify predators and cyberbullies.

March 2009
Fact:  Nearly half of teens (47%) aren't worried about others us ing their personal info in ways they don't want (Teen Research Unlimited. "Cox Communications Teen Internet Safety Survey Wave II, " March 2007).
Tip:  Think about keeping some control over the information you post. Consider restricting access to your page to a select group of people, for example, your firends from school, your club, your team, your community groups, or your family.
February 2009
Fact:  23% of children have had an encounter with a stranger on the Internet, including 7% of children who reported having met someone in the real world from the Internet. (Harris Interactive, "Kids Outsmart Parents When it comes to the Internet," August 2007)
Tip:  Be wary if a new online friend wants to meet you in person.  Before you decide to meet someone, do your research:  Ask whether any of your friends know the person, and see what background you can dig up through online search engines.  If you decide to meet them, be smart about it:  Meet in a public place, during the day, with friends you trust. Tell an adult or a responsible sibling where you're going, and when you expect to be back. 
January 2009
Fact:  69% of teens regularly receive personal messages online from people they don't know and most of them don't tell a trusted adult about it (Teen Research Unlimited, "Cox Communications Teen Internet saftety Survey Wave It," March 2007)
Tip:  Flirting with strangers online could have serious consequences.  Because some people lie about who they really are, you never know who you are dealing with.
December 2008
Fact:  64% of teens post photos or videos of themselves online, while mroe than half (58%) post info about where they live.  Females are far more likely than male teens to post personal photos or videos of themselves (70% vs. 58%) (Teen Research Unlimited. "Cox Communications Teen Internet Safety Wave II." March 2007)
Tip:  Consider not posting your photo.  It can be altered and broadcast in ways you may not be happy about.  If you do post one, ask yourself whether it's one your mom would display in the living room.
November  2008
Fact:  About half (49%) are unconcerned that posting personal info online might negatively affect their future (Teen Research Unlimited.  "Cox Communications Teen Internet safety Survey Wave II, " March 2007)

Tip:  Post only information that you are comfortable with others seeing -- and knowing -- about you.  Many people can see your page, including your parents, your teachers, the police, the college you might want to apply to next year, or the job you might want to apply for in five years.
October  2008

F act:   A mong teens active in social networking sites (like MySpace,Facebook), 61% post the name of their city or town, 49% post their school's name, 29% post their email address, and 29% post their last name (Lenhart, Amanda and Maddox, Mary. "Teens, Privacy, and Online Social Networks - How Teens Manage their Online Identities and Personal Information in the Age of MySpace." April 18, 2007)

Tip:   M ake sure your screen name doesn't say too much about you.  Don't use your name, your age, or your hometown.  Even if you think your screen name makes you anonymous, it doesn't take a genius to combine clues to figure out who you are and where you can be found.

September 2009
Fact:  Four percent of children received aggressive solicitations from adultswho attempted to meet the children in person, compared to 3 percent in 2000. (Love to Know website:  2007 Internet Safety Statistics for Children)
Tip:  Discuss Internet safety with your children, starting when they are very young so they learn how to identify predators and cyberbullies.

The youngest active system of governance is communism, which was introduced in 1848 by Friedrich Engels and Karl
Marx.
The oldest existing governing body operates in Althing in Iceland. It was established in 930 AD.
David “Screaming Lord Sutch”, as leader of the Monster Raving Loony Party, was Britain’s longest serving party leader until he hung himself in June 1999.
Although the United States of America was established in 1776 the first American president ever to visited Europe while in office was Woodrow Wilson in 1918.

Fast facts on US Presidents and Vice Presidents
In 1975, Emil Matalik put himself forward as US Presidential candidate. He advocated a maximum of one animal and
one tree per family because he believed that there were too many animals and plant life on earth. Louis Abalofia also put himself forward: his campaign poster featured a photo of him in the nude, with the slogan “I have nothing to hide.” In the 1860s, financier George Francis Train ran for office with one item: the introduction of a new calender based
on his birth date.
George Washington was inaugurated for his first term, on 30 April 1789, at Federal Hall in New York City. His second inauguration took place in Philadelphia. Thomas Jefferson was the first to be inaugurated in Washington DC. Jefferson also was the only one to walk to and from his inauguration.
William Henry Harrison had the shortest term of office as president. He served from for 32 days, from 4 March to 4 April 1841.
Franklin D. Roosevelt had the longest term of office: 12 years. Roosevelt had three vice presidents serve during his four terms: John Nance Garner (1933-1941), Henry Wallace (1941-1945), Harry Truman (1945).

    (Lycopersicon esculentum)

    Originally cultivated by the Aztecs and Incas as early as 700 A.D., the tomato is native to the Americas. Europeans were first made aware of the tomato when explorers brought back seed from Mexico and Central America in the 16th century. Tomatoes quickly became popular in the Mediterranean countries but received resistance as they spread north. The British in particular considered the fruit to be beautiful but poisonous. This fear was shared in the American colonies and it was years before the tomato gained widespread acceptance. By the middle of the 19th century, tomatoes were in use across America. Today the tomato is generally considered to be the favorite vegetable of the American public.

OCEAN PLANET" MARINE LIFE FACTS


  • The oceans contain 99 percent of the living space on the planet.
  • The blue whale, Balaenoptera musculus, is the largest known animal ever to have lived on sea or land. Individuals can reach more than 110 feet and weigh nearly 200 tons_more than the weight of 50 adult elephants. The blue whale's blood vessels are so broad that a full-grown trout could swim through them, and the vessels serve a heart the size of a small car.
  • Hydrothermal vents, fractures in the sea floor that spew sulphur compounds, support the only complex ecosystem known to run on chemicals, rather than energy from the sun. Gigantic tubeworms and mussels thrive in densities of up to 65 pounds per square foot around vents.
  • The oarfish, Regalecus glesne, is the longest bony fish in the world. With its snakelike body_sporting a magnificent red fin along its 50-foot length_horselike face and blue gills, it accounts for many sea-serpent sightings.
  • Green turtles can migrate more than 1,400 miles to lay their eggs.
  • A group of herring is called a seige. A group of jelly fish is called a smack.
  • Many fish can change sex during the course of their lives. Others, especially rare deep-sea fish, have both male and female sex organs.
  • Oils from the orange roughy, Hoplostethus atlanticus, a deep-sea fish from New Zealand, are used in making shampoo.

Info About Bones


Bones give our wonderful body its structure. Without them, our motion, actions would just cease to exist. Let’s look at some fun facts about bones.
1. The smallest bone in the human body is the stapes or stirrup bone located in the middle ear. It is approximately .11 inches (.28 cm) long. We may owe all our hearing to this little bone shaped like a stirrup, because it transmits sound vibrations through our hearing system!
2. Human thigh bones are stronger than concrete, the Femur bone as it’s called – the biggest and strongest bone in our body. It is easily capable of lifting or supporting 30 times its own volume and weight!
3. There are about 206 bones in a grown-up’s body. But more than half of them are located just in our hands and feet!
4. We have somewhere around 300 to 350 bones that we are born with. As we grow up, the number reduces to 206. Well, they don’t go anywhere, except that sometime around the age between 12 and 14, some of our smaller bones, fuse into larger, big and stronger bones!
5. Apart from having more bones, another interesting baby fact is that they don’t have kneecaps! Well, actually they do but their kneecaps have not yet turned into hard bones, and are still soft cartilage, that gradually hardens into bones. This process is called ossification.
6. By the age of 20, the average young person has acquired roughly 98% of his/her skeletal mass.
7. There are around 14 bones are in the face, 8 bones are in each wrist, 27 bones in each hand, 23 bones are in each foot including the ankle and 30 bones in the skull.
8. Adult human bones account for 14% of the body’s total weight.
9. Bones consist of 50% water and 50% solid matter. They are hard, strong and very much alive like muscle tissue. They also have tons of living cells which help them grow and repair themselves. If bones weren’t made of living cells, things like broken toes or arms would never mend.
10. Bone marrow is found in the hollow bones, that produces new red and white blood cells. Consider it the factory for the blood constituents.
11. Our ribs move about 5 million times a year, every time we breathe!
12. When there’s not enough calcium in the bloodstream, the body attempts to pull calcium from the bones, which thins and weakens them. This causes osteoporosis, which leads to breaks and fractures.
13. Did you know that humans and giraffes have the same number of bones in their necks i.e. 8? Giraffe neck vertebrae are just much, much longer!
14. We have over 230 moveable and semi-moveable joints in our body.

TItanic Information


  1. Canceled Lifeboat Drill
    Originally, a lifeboat drill was scheduled to take place on board the Titanic on April 14, 1912 - the day the Titanic hit the iceberg. However, for an unknown reason, Captain Smith canceled the drill. Many believe that had the drill taken place, more lives could have been saved.
  2. Only Seconds
    From the time the lookouts sounded the alert, the officers on the bridge had only 37 seconds to react before the Titanic hit the iceberg. In that time, First Officer Murdoch ordered "hard a-starboard" (sharp left turn). He also ordered the engine room to put the engines in reverse. The Titanic did bank left, but it wasn't quite enough.
  3. The Titanic's Newspaper
    The Titanic seemed to have everything on board, including its own newspaper. The Atlantic Daily Bulletin was printed every day on board the Titanic. The newspaper included news, advertisements, stock prices, horse-racing results, society gossip, and the day's menu.
  4. Lifeboats Not Full
    Not only were there not enough lifeboats to save everyone on board, most of the lifeboats that were launched off the Titanic were not filled to capacity. For instance, the first lifeboat to launch, Lifeboat 7 from the starboard side) only carried 24 people, despite having a capacity of 65 (two additional people later transferred to Lifeboat 7 from Lifeboat 5). However, it was Lifeboat 1 that carried the fewest people - only seven crew and five passengers (a total of 12 people) despite having a capacity for 40.
  5. Only Two Bathtubs
    Although most passengers had to share bathrooms (only the two promenade suites in first class had private bathrooms), third class had it rough with only two bathtubs for more than 700 passengers.
  6. Another Boat Was Closer for Rescue
    When the Titanic began sending out distress signals, the Californian, rather than theCarpathia, was the closest ship; yet the Californian did not respond until it was much too late to help. At 12:45 a.m. on April 15, 1912, crew members on the Californian saw mysterious lights in the sky (the distress flares sent up from the Titanic) and woke up their captain to tell him about it. Unfortunately, the captain issued no orders. Since the ship's wireless operator had already gone to bed, the Californian was unaware of any distress signals from the Titanic until the morning, but by then the Carpathia had already picked up all the survivors. Many people believe that if the Californian had responded to the Titanic's pleas for help, many more lives could have been saved.
  7. Two Dogs Rescued
    With the order for women and children first into the lifeboats, plus the knowledge that there were not enough lifeboats for everyone on board the Titanicto be saved, it is a bit surprising that two dogs made it into the lifeboats. Of the nine dogs on board theTitanic, the two that were rescued were a Pomeranian and a Pekinese.
  8. The Fourth Funnel
    In what is now an iconic image, the side view of the Titanic clearly shows four cream and black funnels. While three of these released the steam from the boilers, the fourth was just for show. The designers thought the ship would look more impressive with four funnels rather than three.
  9. A Royal Mail Ship
    The R.M.S. Titanic was a Royal Mail Ship, a designation which meant the Titanic was officially responsible for delivering mail for the British postal service. On board the Titanicwas a Sea Post Office with five mail clerks (two British and three American). These mail clerks were responsible for the 3,423 sacks of mail (seven million individual pieces of mail) on board the Titanic. Interestingly, although no mail has yet been recovered from the wreck of the Titanic, if it were, the U.S. Postal Service would still try to deliver it (the USPS because most of the mail was being sent to the U.S.).
  10. Corpses Recovered
    On April 17, 1912, the day before survivors of the Titanic disaster reached New York, theMackay-Bennett was sent off from Halifax, Nova Scotia to search for bodies. On board theMackay-Bennett were embalming supplies, 40 embalmers, tons of ice, and 100 coffins. Although the Mackay-Bennett found 306 bodies, 116 of these were too badly damaged to take all the way back to shore. Attempts were made to identify each body found. Additional ships were also sent out to look for bodies. In all, 328 bodies were found, but 119 of these were badly damaged and thus were buried at sea.

Discovery of Gold


Photograph of John Sutter
It was in the first part of January, 1848, when the gold was discovered at Coloma, where I was then building a saw-mill. The contractor and builder of this mill was James W. Marshall, from New Jersey. In the fall of 1847, after the mill seat had been located, I sent up to this place Mr. P. L. Wimmer with his family, and a number of laborers, from the disbanded Mormon Battalion; and a little later I engaged Mr. Bennet from Oregon to assist Mr. Marshall in the mechanical labors of the mill. Mr. Wimmer had the team in charge, assisted by his young sons, to do the necessary teaming, and Mrs. Wimmer did the cooking for all hands.
I was very much in need of a new saw-mill, to get lumber to finish my large flouring mill, of four run of stones, at Brighton, which was commenced at the same time, and was rapidly progressing; likewise for other buildings, fences, etc., for the small village of Yerba Buena, (now San Francisco.) In the City Hotel, (the only one) at the dinner table this enterprise was unkindly called “another folly of Sutter’s,” as my first settlement at the old fort near Sacramento City was called by a good many, “a folly of his,” and they were about right in that, because I had the best chances to get some of the finest locations near the settlements; and even well stocked rancho’s had been offered to me on the most reasonable conditions; but I refused all these good offers, and preferred to explore the wilderness, and select a territory on the banks of the Sacramento. It was a rainy afternoon when Mr. Marshall arrived at my office in the Fort, very wet. I was somewhat surprised to see him, as he was down a few days previous; and then, I sent up to Coloma a number of teams with provisions, mill irons, etc., etc. He told me then that he had some important and interesting news which he wished to communicate secretly to me, and wished me to go with him to a place where we should not be disturbed, and where no listeners could come and hear what we had to say. I went with him to my private rooms; he requested me to lock the door; I complied, but I told him at the same time that nobody was in the house except the clerk, who was in his office in a different part of the house; after requesting of me something which he wanted, which my servants brought and then left the room, Photograph of John Marshall, who discovered goldI forgot to lock the doors, and it happened that the door was opened by the clerk just at the moment when Marshall took a rag from his pocket, showing me the yellow metal: he had about two ounces of it; but how quick Mr. M. put the yellow metal in his pocket again can hardly be described. The clerk came to see me on business, and excused himself for interrupting me, and as soon as he had left I was told, “now lock the doors; didn’t I tell you that we might have listeners?” I told him that he need fear nothing about that, as it was not the habit of this gentleman; but I could hardly convince him that he need not to be suspicious. Then Mr. M. began to show me this metal, which consisted of small pieces and specimens, some of them worth a few dollars; he told me that he had expressed his opinion to the laborers at the mill, that this might be gold; but some of them were laughing at him and called him a crazy man, and could not believe such a thing.
After having proved the metal with aqua fortis, which I found in my apothecary shop, likewise with other experiments, and read the long article “gold” in the Encyclopedia Americana, I declared this to be gold of the finest quality, of at least 23 carats. After this Mr. M. had no more rest nor patience, and wanted me to start with him immediately for Coloma; but I told him I could not leave as it was late in the evening and nearly supper time, and that it would be better for him to remain with me till the next morning, and I would travel with him, but this would not do: he asked me only “will you come to-morrow morning?” I told him yes, and off he started for Coloma in the heaviest rain, although already very wet, taking nothing to eat. I took this news very easy, like all other occurrences good or bad, but thought a great deal during the night about the consequences which might follow such a discovery. I gave all my necessary orders to my numerous laborers, and left the next morning at 7 o’clock, accompanied by an Indian soldier, and vaquero, in a heavy rain, for Coloma. About half way on the road I saw at a distance a human being crawling out from the brushwood. I asked the Indian who it was: he told me “the same man who was with you last evening.” When I came nearer I found it was Marshall, very wet; I told him that he would have done better to remain with me at the fort than to pass such an ugly night here but he told me that he went up to Coloma, (54 miles) took his other horse and came half way to meet me; then we rode up to the new Eldorado. In the afternoon the weather was clearing up, and we made a prospecting promenade. The next morning we went to the tail-race of the mill, through which the water was running during the night, to clean out the gravel which had been made loose, for the purpose of widening the race; and after the water was out of the race we went in to search for gold. This was done every morning: small pieces of gold could be seen remaining on the bottom of the clean washed bed rock. I went in the race and picked up several pieces of this gold, several of the laborers gave me some which they had picked up, and from Marshall I received a part. I told them that I would get a ring made of this gold as soon as it could be done in California; and I have had a heavy ring made, with my family’s cost of arms engraved on the outside, and on the inside of the ring is engraved, “The first gold, discovered in January, 1848.” Now if Mrs. Wimmer possesses a piece which has been found earlier than mine Mr. Marshall can tell, as it was probably received from him. I think Mr. Marshall could have hardly known himself which was exactly the first little piece, among the whole.
The next day I went with Mr. M. on a prospecting tour in the vicinity of Coloma, and the following morning I left for Sacramento. Before my departure I had a conversation with all hands: I told them that I would consider it as a great favor if they would keep this discovery secret only for six weeks, so that I could finish my large flour will at Brighton, (with four run of stones,) which had cost me already about from 24 to 25,000 dollars – the people up there promised to keep it secret so long. On my way home, instead of feeling happy and contented, I was very unhappy, and could not see that it would benefit me much, and I was perfectly right in thinking so; as it came just precisely as I expected. I thought at the same time that it could hardly be kept secret for six weeks, and in this I was not mistaken, for about two weeks later, after my return, I sent up several teams in charge of a white man, as the teamsters were Indian boys. This man was acquainted with all hands up there, and Mrs. Wimmer told him the whole secret; likewise the young sons of Mr. Wimmer told him that they had gold, and that they would let him have some too; and so he obtained a few dollars’ worth of it as a present. As soon as this man arrived at the fort he went to a small store in one of my outside buildings, kept by Mr. Smith, a partner of Samuel Brannan, and asked for a bottle of brandy, for which he would pay the cash; after having the bottle he paid with these small pieces of gold. Smith was astonished and asked him if he intended to insult him; the teamster told him to go and ask me about it; Smith came in, in great haste, to see me, and I told him at once the truth – what could I do? I had to tell him all about it. He reported it to Mr. S. Brannan, who came up immediately to get all possible information, when he returned and sent up large supplies of goods, leased a larger house from me, and commenced a very large and profitable business; soon he opened a branch house of business at Mormon Island.
Photograph of Sam BrannanMr. Brannan made a kind of claim on Mormon Island, and put a tolerably heavy tax on “The Latter Day Saints.” I believe it was 30 per cent, which they paid for some time, until they got tired of it, (some of them told me that it was for the purpose of building a temple for the honor and glory of the Lord.)
So soon as the secret was out my laborers began to leave me, in small parties first, but then all left, from the clerk to the cook, and I was in great distress; only a few mechanics remained to finish some very necessary work which they had commenced, and about eight invalids, who continued slowly to work a few teams, to scrape out the mill race at Brighton. The Mormons did not like to leave my mill unfinished, but they got the gold fever like everybody else. After they had made their piles they left for the Great Salt Lake. So long as these people have been employed by me they hav behaved very well, and were industrious and faithful laborers, and when settling their accounts there was not one of them who was not contented and satisfied.
Then the people commenced rushing up from San Francisco and other parts of California, in May, 1848: in the former village only five men were left to take care of the women and children. The single men locked their doors and left for “Sutter’s Fort,” and from there to the Eldorado. For some time the people in Monterey and farther south would not believe the news of the gold discovery, and said that it was only a ‘Ruse de Guerre’ of Sutter’s, because he wanted to have neighbors in his wilderness. From this time on I got only too many neighbors, and some very bad ones among them.
What a great misfortune was this sudden gold discovery for me! It has just broken up and ruined my hard, restless, and industrious labors, connected with many dangers of life, as I had many narrow escapes before I became properly established.
From my mill buildings I reaped no benefit whatever, the mill stones even have been stolen and sold.
My tannery, which was then in a flourishing condition, and was carried on very profitably, was deserted, a large quantity of leather was left unfinished in the vats; and a great quantity of raw hides became valueless as they could not be sold; nobody wanted to be bothered with such trash, as it was called. So it was in all the other mechanical trades which I had carried on; all was abandoned, and work commenced or nearly finished was all left, to an immense loss for me. Even the Indians had no more patience to work alone, in harvesting and threshing my large wheat crop out; as the whites had all left, and other Indians had been engaged by some white men to work for them, and they commenced to have some gold for which they were buying all kinds of articles at enormous prices in the stores; which, when my Indians saw this, they wished very much to go to the mountains and dig gold. At last I consented, got a number of wagons ready, loaded them with provisions and goods of all kinds, employed a clerk, and left with about one hundred Indians, and about fifty Sandwich Islanders (Kanakas) which had joined those which I brought with me from the Islands. The first camp was about ten miles above Mormon Island, on the south fork of the American river.
In a few weeks we became crowded ,and it would no more pay, as my people made too many acquaintances. I broke up the camp and started on the march further south, and located my next camp on Sutter creek (now in Amador county), and thought that I should there be alone. The work was going on well for a while, until three or four traveling grog-shops surrounded me, at from one and 8, half to two miles distance from the camp; then, of course, the gold was taken to these places, for drinking, gambling, etc., and then the following day they were sick and unable to work, and became deeper and more indebted to me, and particularly the Kanakas. I found that it was high time to quit this kind of business, and lose no more time and money. I therefore broke up the camp and returned to the Fort, where I disbanded nearly all the people who had worked for me in the mountains digging gold. This whole expedition proved to be a heavy loss to me.
At the same time I was engaged in a mercantile firm in Coloma, which I left in January, 1849 – likewise with many sacrifices. After this I would have nothing more to do with the gold affairs. At this time, the Fort was the great trading place where nearly all the business was transacted. I had no pleasure to remain there, and moved up to Hock Farm, with all my Indians, and who had been with me from the time they were children. The place was then in charge of a Major Domo.
It is very singular that the Indians never found a piece of gold and brought it to me, as they very often did other specimens found in the ravines. I requested them continually to bring me some curiosities from the mountains, for which I always recompensed them. I have received animals, birds, plants, young trees, wild fruits, pipe clay, stones, red ochre, etc., etc., but never a piece of gold. Mr. Dana of the scientific corps of the expedition under Com. Wilkes’ Exploring Squadron, told me that he had the strongest proof and signs of gold in the vicinity of Shasta Mountain, and furthers south. A short time afterwards, Doctor Sandels, a very scientific traveler, visited me, and explored a part of the country in a great hurry, as time would not permit him to make a longer stay.
He told me likewise that he found sure signs of gold, and was very sorry that be could not explore the Sierra Nevada. He did not encourage me to attempt to work and open mines, as it was uncertain how it would pay and would probably be only for a government. So I thought it more prudent to stick to the plow, not withstanding I did know that the country was rich in gold, and other minerals. An old attached Mexican servant who followed me here from the United States, as soon as he knew that I was here, and who understood a great deal about working in placers, told me he found sure signs of gold in the mountains on Bear Creek, and that we would go right to work after returning from our campaign in 1845, but he became a victim to his patriotism and fell into the hands of the enemy near my encampment, with dispatches for me from Gen. Micheltorena, and he was hung as a spy, for which I was very sorry.
By this sudden discovery of the gold, all my great plans were destroyed. Had I succeeded for a few years before the gold was discovered, I would have been the richest citizen on the Pacific shore; but it had to be different. Instead of being rich, I am ruined, and the cause of it is the long delay of the United States Land Commission of the United States Courts, through the great influence of the squatter lawyers. Before my case will be decided in Washington, another year may elapse, but I hope that justice will be done me by the last tribunal — the Supreme Court of the United States. By the Land Commission and the District Court it has been decided in my favor. The Common Council of the city of Sacramento, composed partly of squatters, paid Adelpheus Felch, (one of the late Land Commissioners, who was engaged by the squatters during his office), $5,000, from the fund of the city, against the will of the tax-payers, for which amount he has to try to defeat my just and old claim from the Mexican government, before the Supreme Court of the United States in Washington.

The African elephant and the Asian elephant are the only two surviving species of what was in prehistoric times a diverse and populous group of large mammals. Fossil records suggest that the elephant has some unlikely distant relatives, namely the small, rodentlike hyrax and the ungainly aquatic dugong. They all are thought to have evolved from a common stock related to ungulates. In East Africa many well-preserved fossil remains of earlier elephants have aided scientists in dating the archaeological sites of prehistoric man.

Physical Characteristics
The African elephant is the largest living land mammal, one of the most impressive animals on earth.
Of all its specialized features, the muscular trunk is the most remarkable it serves as a nose, a hand, an extra foot, a signaling device and a tool for gathering food, siphoning water, dusting, digging and a variety of other functions. Not only does the long trunk permit the elephant to reach as high as 23 feet, but it can also perform movements as delicate as picking berries or caressing a companion. It is capable, too, of powerful twisting and coiling movements used for tearing down trees or fighting. The trunk of the African elephant has two finger-like structures at its tip, as opposed to just one on the Asian elephant (Elephas maximus).

The tusks, another remarkable feature, are greatly elongated incisors (elephants have no canine teeth); about one-third of their total length lies hidden inside the skull. The largest tusk ever recorded weighed 214 pounds and was 138 inches long. Tusks of this size are not found on elephants in Africa today, as over the years hunters and poachers have taken animals with the largest tusks. Because tusk size is an inherited characteristic, it is rare to find one now that would weigh more than 100 pounds.

Both male and female African elephants have tusks, although only males in the Asiatic species have them. Tusks grow for most of an elephant's lifetime and are an indicator of age. Elephants are "right- or left-tusked," using the favored tusk more often as a tool, thus, shortening it from constant wear. Tusks will differ in size, shape and direction; researchers use them (and the elephant's ears) to identify individuals.

Although the elephant's remaining teeth do not attract the ivory poacher, they are nonetheless interesting and ultimately determine the natural life span of the elephant. The cheek teeth erupt in sequence from front to rear (12 on each side, six upper and six lower), but with only a single tooth or one and a part of another, being functional in each half of each jaw at one time. As a tooth becomes badly worn, it is pushed out and replaced by the next tooth growing behind. These large, oblong teeth have a series of cross ridges across the surface. The last molar, which erupts at about 25 years, has the greatest number of ridges but must also serve the elephant for the rest of its life. When it has worn down, the elephant can no longer chew food properly; malnutrition sets in, hastening the elephant's death, usually between 60 and 70 years of age.

The African elephant's ears are over twice as large as the Asian elephant's and have a different shape, often described as similar to a map of Africa. The nicks, tears and scars as well as different vein patterns on the ears help distinguish between individuals. Elephants use their ears to display, signal or warn when alarmed or angry, they spread the ears, bringing them forward and fully extending them. The ears also control body temperature. By flapping the ears on hot days, the blood circulates in the ear's numerous veins; the blood returns to the head and body about 9 F cooler.

The sole of the elephant's foot is covered with a thick, cushionlike padding that helps sustain weight, prevents slipping and deadens sound. When they need to, elephants can walk almost silently. An elephant usually has five hoofed toes on each forefoot and four on each hind foot. When it walks, the legs on one side of the body move forward in unison.

Sometimes it is difficult for the layman to distinguish between male and female elephants as the male has no scrotum (the testes are internal), and both the male and the female have loose folds of skin between the hind legs. Unlike other herbivores, the female has her two teats on her chest between her front legs. As a rule, males are larger than females and have larger tusks, but females can usually be identified by their pronounced foreheads.

Habitat
Elephants can live in nearly any habitat that has adequate quantities of food and water. Their ideal habitat consists of plentiful grass and browse.

Behavior
Elephants are generally gregarious and form small family groups consisting of an older matriarch and three or four offspring, along with their young. It was once thought that family groups were led by old bull elephants, but these males are most often solitary. The female family groups are often visited by mature males checking for females in estrus. Several interrelated family groups may inhabit an area and know each other well. When they meet at watering holes and feeding places, they greet each other affectionately.

Females mature at about 11 years and stay in the group, while the males, which mature between 12 and 15, are usually expelled from the maternal herd. Even though these young males are sexually mature, they do not breed until they are in their mid- or late 20s (or even older) and have moved up in the social hierarchy. Mature male elephants in peak condition experience an annual period of heightened sexual and aggressive activity called musth. During this period, which may last a week or even up to three to four months, the male produces secretions from swollen temporal glands, continuously dribbles a trail of strong-smelling urine and makes frequent mating calls. Females are attracted to these males and prefer to mate with them rather than with males not in musth.

Smell is the most highly developed sense, but sound deep growling or rumbling noises is the principle means of communication. Some researchers think that each individual has its signature growl by which it can be distinguished. Sometimes elephants communicate with an ear-splitting blast when in danger or alarmed, causing others to form a protective circle around the younger members of the family group. Elephants make low-frequency calls, many of which, though loud, are too low for humans to hear. These sounds allow elephants to communicate with one another at distances of five or six miles.

Diet
An elephant's day is spent eating (about 16 hours), drinking, bathing, dusting, wallowing, playing and resting (about three to five hours). As an elephant only digests some 40 percent of what it eats, it needs tremendous amounts of vegetation (approximately 5 percent of its body weight per day) and about 30 to 50 gallons of water. A young elephant must learn how to draw water up into its trunk and then pour it into its mouth. Elephants eat an extremely varied vegetarian diet, including grass, leaves, twigs, bark, fruit and seed pods. The fibrous content of their food and the great quantities consumed makes for large volumes of dung.

Caring for the Young
Usually only one calf is born to a pregnant female. An orphaned calf will usually be adopted by one of the family's lactating females or suckled by various females. Elephants are very attentive mothers, and because most elephant behavior has to be learned, they keep their offspring with them for many years. Tusks erupt at 16 months but do not show externally until 30 months. The calf suckles with its mouth (the trunk is held over its head); when its tusks are 5 or 6 inches long, they begin to disturb the mother and she weans it. Once weaned usually at age 4 or 5, the calf still remains in the maternal group.

Predators
Elephants once were common throughout Africa, even in northern Africa as late as Roman times. They have since disappeared from that area due to overhunting and the spread of the desert. Even though they are remarkably adaptable creatures, living in habitats ranging from lush rain forest to semidesert, there has been much speculation about their future. Surviving populations are pressured by poachers who slaughter elephants for their tusks and by rapidly increasing human settlements, which restrict elephants' movements and reduce the size of their habitat. Today it would be difficult for elephants to survive for long periods of time outside protected parks and reserves. But confining them also causes problems without access any longer to other areas, they may harm their own habitat by overfeeding and overuse. Sometimes they go out of protected areas and raid nearby farms.

Info About Dolphin


1. Dolphins are mammals.
As all mammals, dolphins nurse their young from mammary glands.
2. Dolphins can swim up to 260 m. below the surface of the ocean.
However they are mainly shallow divers as they need to reach the surface to breathe.


3. Dolphins can stay up to 15 minutes under water.

They only do this some times as they usually stay only a few minutes diving before reaching the surface for air.

4. Dolphins use a technique called echolocation.

This technique uses the same principles of a radar, and it is used to find food and navigate.

5. Dolphins are social beings.

Dolphins live in groups and cooperate among each other for activities like getting food and calf rising.


6. Dolphins are Cetacenas.


There are 32 species of ocean dolphins and 5 species of river dolphins.

7. The largest dolphin is the Orca, also known as “killer whale”.

Orcas grow up to 6.1 meters long and they are named as whales because their size, but they really belong to the toothed cetacean family just like dolphins do.

8. The most popular dolphin is the “bottlenose dolphin".

Bottlenose dolphins are the ones we have seen in tv series, movies and aquatic shows. Bottlenose dolphins can grow up to 2.5-2.8 meters.

9. Dolphins are warm-blooded.

As mammals, dolphins are warm blooded and their internal temperature is around 36 degrees. To conserve this temperature they are surrounded by a thick layer of fat called “blubber” just below the skin.

10. The botllenose dolphin brain weighs 1500-1600 grams.

While average human brain weighs 1200-1300 grs. This is not a conclusive evidence of dolphin intelligence as many other factors might be the cause of intelligence according to scientists.
11. Dolphins communicate efficiently.

Dolphins can make a unique signature whistle that may help individual dolphins recognize
each other, collaborate and perform several other kinds of communication.

12. D olphins can swim 5 to 12 kilometers per hour.
This will depend on the species and situation, although fastest dolphins can reach up to 32 km/h.

Info About China


The history of China reaches back over 5,000 years. In that time, China has created a culture rich in philosophy and the arts. China has seen the invention of amazing products and technologies such as silk, paper, gunpowder, and movable-type printing.
Over the millennia, China has fought hundreds of wars. It has conquered its neighbors, and been conquered by them in turn. Early Chinese explorers sailed all the way to Africa; today, China's space program continues this tradition of exploration.
This snapshot of the People's Republic of China today includes a necessarily brief scan of China's ancient heritage.

Capital and Major Cities:

Capital:
Beijing, population 11 million.

Major Cities:
Shanghai, population 15 million.
Shenzhen, population 12 million.
Guangzhou, population 7 million.
Hong Kong, population 7 million.
Dongguan, population 6.5 million.
Tianjin, population 5 million.

Government:

The People's Republic of China is a socialist republic ruled by a single party, the Communist Party of China.
Power in the People's Republic is divided between the National People's Congress (NPC), the President, and the State Council. The NPC is the single legislative body, whose members are selected by the Communist Party. The State Council, headed by the Premier, is the administrative branch. The People's Liberation Army also wields considerable political power.
The current President of China and General Secretary of the Communist Party is Hu Jintao. The Premier is Wen Jiabao.

Official Language:

The official language of the PRC is Mandarin, a tonal language in the Sino-tibetan family. Within China, however, only about 53 per cent of the population can communicate in Standard Mandarin.
Other important languages in China include Wu, with 77 million speakers; Min, with 60 million; Cantonese, 56 million speakers; Jin, 45 million speakers; Xiang, 36 million; Hakka, 34 million; Gan, 29 million; Uyghur, 7.4 million; Tibetan, 5.3 million; Hui, 3.2 million; and Ping, with 2 million speakers.
Dozens of minority languages also exist in the PRC, including Kazakh, Miao, Sui, Korean, Lisu, Mongolian, Qiang, and Yi.

Population:

China has the largest population of any country on Earth, with more than 1.3 billion people.
The government has long been concerned about population growth, and introduced the "One-Child Policy" in 1979. Under this policy, families are limited to just one child. Couples who get pregnant for a second time may face forced abortions or sterilization.
There are exceptions to the policy for ethnic minorities. Rural families also may have a second child if the first is a girl, or has disabilities. In practice, many urban families also "buy" permission to have a second baby, particularly if they have a daughter.

Religion:

Under the communist system, religion has been officially discouraged in China. Actual suppression has varied from one religion to another, and from year to year.
Many Chinese are nominally Buddhist and/or Taoist, but don't practice regularly. People who self-identify as Buddhist total about 50 per cent, overlapping with the 30 per cent who are Taoist. Fourteen percent are atheists, four percent Christians, 1.5 per cent Moslems, and tiny percentages are Hindu, Bon, or Falun Gong adherents.
Most Chinese Buddhists follow Mahayana or Pure Land Buddhism, with smaller populations of Theravada and Tibetan Buddhists.

Geography:

China's area is 9.5 to 9.8 million square kilometers; the discrepancy is due to border disputes with India. In either case, its size is second only to Russia in Asia, and is either third or fourth in the world.
China borders 14 countries: AfghanistanBhutanBurma, India, KazakhstanNorth Korea,Kyrgyzstan, Laos, MongoliaNepalPakistan, Russia, Tajikistan, and Vietnam.
From the world's tallest mountain to the coast, and the Taklamakan desert to the jungles of Guilin, China includes diverse landforms.
The highest point is Mt. Everest (Chomolungma) at 8,850 meters. The lowest is Turpan Pendi, at -154 meters.

Climate:

As a result of its large area and various landforms, China includes climate zones from subarctic to tropical.
China's northern province of Heilongjiang has average winter temperatures below freezing, with record lows of -30 degrees Celsius. Xinjiang, in the west, can reach nearly 50 degrees. Southern Hainan Island has a tropical monsoon climate. Average temperatures there range only from about 16 degrees Celsius in January to 29 in August.
Hainan receives about 200 centimeters (79 inches) of rain annually. The western Taklamakan Desert receives only about 10 centimeters (4 inches) of rain and snow per year.

Economy:

Over the past 25 years, China has had the fastest-growing major economy in the world, with annual growth of more than 10 per cent.
Nominally a socialist republic, since the 1970s the PRC has remade its economy into a capitalist powerhouse.
Industry and agriculture are the largest sectors, producing more than 60 per cent of China's GDP, and employing over 70 per cent of the work force. China exports $1.2 billion U.S. in consumer electronics, office machinery, and apparel, as well as some agricultural produce each year.
Per capita GDP is $2,000. The official poverty rate is 10 per cent.
China's currency is the yuan.

History of China:

Chinese historical records reach back into the realm of legend, 5,000 years ago. It is impossible to cover even the major events of this ancient culture in a short space, but here are some highlights.
The first non-mythical dynasty to rule China was the Xia (2200- 1700 B.C.), founded by Emperor Yu. It was succeeded by the Shang Dynasty (1600-1046 B.C.), and then the Zhou Dynasty (1122-256 B.C.). Historical records are scanty for these ancient dynastic times.
In 221 B.C., Qin Shi Huang assumed the throne, conquered neighboring city-states, and unified China. He founded the Qin Dynasty, which lasted only until 206 B.C. Today, he is best-known for his tomb complex in Xian, which houses the incredible Army of Terracotta Warriors.
Qin Shi Huang's inept heir was overthrown by the army of commoner Liu Bang in 207 B.C. Liu then founded the Han Dynasty, which lasted until 220 A.D. In the Han era, China expanded west as far as India, opening trade along what would later become the Silk Road.
When the Han Empire collapsed in 220 A.D., China was thrown into a period of anarchy and turmoil. For the next four centuries, dozens of kingdoms and fiefdoms competed for power. This era is called the "Three Kingdoms," after the three most powerful of the rival realms (Wei, Shu, and Wu), but that is a gross simplification.
By 589 A.D., the Western branch of the Wei kings had accumulated enough wealth and power to defeat their rivals, and unite China once more. The Sui Dynasty was founded by Wei general Yang Jian, and ruled until 618 A.D. It built the legal, governmental, and societal framework for the powerful Tang Empire to follow.
The Tang Dynasty was founded by a general called Li Yuan, who had the Sui emperor assassinated. The Tang ruled from 618 to 907 A.D., and Chinese art and culture flourished. At the end of the Tang, China decended into chaos again in the "5 Dynasties and 10 Kingdoms" period.
In 959, a palace guard named Zhao Kuangyin took power and defeated the other small kingdoms. He established the Song Dynasty (960-1279), known for its intricate bureaucracy and Confucian learning.
In 1271, the Mongolian Kublai Khan (grandson of Genghis) established the Yuan Dynasty(1271-1368). The Mongols subjugated other ethnic groups including Han Chinese, and were overthrown by the Han Ming.
China flowered again under the Ming (1368-1644), creating great art and exploring as far as Africa.
The last Chinese dynasty, the Qing, ruled from 1644 to 1911, when it was overthrown by Sun Yat-Sen, touching off the Chinese Civil War. Although the war was interrupted for a decade by the Japanese invasion and World War II, it picked up again once Japan was defeated. Mao Zedong and the Communist Peoples Liberation Army won the Chinese Civil War, and China became the Peoples' Republic of China in 1949. Chiang Kai Shek, leader of the losing Nationalist forces, fled to Taiwan.
