[L. camelus."] A most useful ruminating animal, which for centuries has been used as a beast of burden or ship of the desert on the sandy plains of Africa and Arabia. It is well adapted by nature for life on the desert. It can go for many days without water, being provided with a remarkable arrangement of cells in its stomach or paunch which it fills with water, and keeps as a store for future use. Its two long toes rest on a broad, horny cushion, which enables it to walk without sinking in the sand, and its nostrils can be closed at will to shut out the fine dust of the sand-storms. The African or Arabian camel has one hump, and is called the dromedary. The Bactrian camel of Central Asia has two humps. The hump is not a part of the skeleton, but is a mass of fat which slowly lessens when the animal is on long journeys and food is scarce, it being consumed as nutriment. The camel is about six feet in height, and not very rapid in speed. It is very useful to the Arab, conveying himself and his belongings on a journey, and yielding him flesh and milk for food, hair for weaving into a covering, and hides for sandals and saddles. Camel hair is used for painters' brushes.
