If you were stranded on a desert island and you wanted to get something from one place to another, what would you do? You would carry it! In primitive times human muscles were the only means of transporting anything. Man was his own “beast of burden.”

In time man tamed certain animals and taught them to carry riders or other loads. The ox, the donkey, the water buffalo, the horse, and the camel were used by early man in various parts of the world for transportation.
