Now I must tell you how camels are used. First, they carry goods for trade. In those countries there are hardly any railroads, so the merchants carry their packages on camels. Of course they could not put a package right on a camel's hump, as it would fall off; so they always join two packages together with a band or belt, and sling the band across the camel's back, so that there is a package on each side of the camel.

When a One-Hump camel is used, the band or belt has two parts, like a loop; and the loop rests over the hump, so that the band cannot slip backward or forward. When a Two-Humps camel is used, the band of course rests in the gap between the two humps, so that it cannot slip at all; and then the two packages can be made very big. That is why people like the Two-Humps camel better for carrying goods, and like the One-Hump camel better for riding. But in some places the One-Hump camel is used both for riding and for carrying goods.

In this way merchants carry their goods for many hundred miles across desert and country. Then sometimes they come to the sea and send the goods in ships to different countries. That is how you get many of the figs, dates, and grapes you eat; so the next time you eat them, think of the patient camel that brought them for you across the desert. That is why the camel is called the Ship of the Desert.

The beautiful carpets and rugs and shawls which you see in rich homes have also been brought by the patient camels; and some of the lovely vases and ornaments that rich people have were also carried by camels. And not only across the desert, but even over ordinary land camels carry these goods. The camel is such a large animal that he can carry packages as heavy as four men.

Of course when he carries such a heavy load, he cannot go any faster than a man's walk; but the camel can keep on walking all day, with just a short rest once in a while. Those used for riding cannot run as fast as a horse, but they can keep on running at a steady trot much longer than a horse, and then after a short rest can start running again. So by the end of the day a camel can run twice as far as a horse, and sometimes still farther.

The Camel's Wonderful Gifts

Now I am going to tell you of the most wonderful things a camel can do.

First, I must tell you that no other animal could cross a desert at all. To begin with, if such an animal as a horse tried to walk on the sand, his hoofs would sink into the sand up to the ankles, and it would be hard work for him to go even a mile. But a camel's foot is different. It has a soft pad of muscles under it, just like a cushion; and when the camel walks or runs on the sand, the pad spreads out under his foot, and that gives him a firm hold on the sand in walking or running. So remember that the camel has padded feet.

I must tell you here that the feet of all animals are formed in the way they can best use, in the country in which they live. Those animals that have to walk on hard ground have hoofs, and those that have to walk on soft ground have padded feet. The elephant is the only animal that has to walk on hard ground, at least very often, and yet has padded feet. Can you tell why? Because of his huge weight! He is so heavy that if the bones under his feet were not covered with a thick pad, he would jar the bones every time he put his foot down, even if the ground were not very hard.
