Finding enough meat was a problem for primitive man Keeping it when it was scarce was just as hard, Three ways were found to keep meat from spoiling: salting, drying, and freezing.
People near salty waters salted their meat. At first, they probably rubbed dry salt on it. but this preserved only the outside. Later they may have pickled their meat by soaking it in salt water.
In hot, dry lands, men found that they could eat meat that had dried while it was still on the bones. They later learned to cat meat into thin stops and hang it up to dry in the hot air
Men in cold climates found that frozen meat did not spoil. They could leave their meat outside and eat it when they pleased.

Jack London was a famous American writer. He was born on January 12, 1876, in San Francisco, California. His family was very poor, and Jack had to leave school to make money. He worked hard in many different jobs.
Later, Jack returned to school, but he didn’t stay. He wrote, "Life and pocketbook were both too short."
In 1897, he went to Alaska to find gold. Instead, he found ideas there for his books and stories. He returned home and started to write. His writings were successful, and he became rich and famous in his twenties.
Jack London was not a happy man, however. In poor health, he took his own life in 1916. He was only 40 years old.
