In the large illustration are represented four of the ordinary Camels of burden, as they appear when laden with boughs for the Feast of Tabernacles. The branches are those of the Hebrew pine, and, as may be seen, the animals are so heavily laden with them that their forms are quite hidden under their leafy burdens. The weight which a Camel will carry varies much, according to the strength of the individual, which has given rise to the Oriental proverb, "As the camel, so the load." But an animal of ordinary strength is supposed to be able to carry from five to six hundred pounds for a short journey, and half as much for a long one,--a quantity which, as the reader will see, is not so very great when the bulk of the animal is taken into consideration. It is remarkable that the Camel knows its own powers, and instinctively refuses to move if its correct load be exceeded. But, when it is properly loaded, it will carry its burden for hours together at exactly the same pace, and without seeming more fatigued than it was when it started. [Illustration: CAMELS LADEN WITH BOUGHS.] [Illustration: MORNING IN THE DESERT: STARTING OF THE CARAVAN.] The riding Camels are always of a better breed than those which are used for burden, and maybe divided into two classes; namely, those which are meant for ordinary purposes, and those which are specially bred for speed and endurance. There is as much difference between the ordinary riding Camel and the swift Camel as there is between the road hack and the race-horse. We will first begin with the description of the common riding Camel and its accoutrements. The saddle which is intended for a rider is very different from the pack-saddle on which burdens are carried, and has a long upright projection in front, to which the rider can hold if he wishes it. The art of riding the Camel is far more difficult of accomplishment than that of riding the horse, and the preliminary operation of mounting is not the least difficult portion of it. Of course, to mount a Camel while the animal is standing is impossible, and accordingly it is taught to kneel until the rider is seated. Kneeling is a natural position with the Camel, which is furnished with large callosities or warts on the legs and breast, which act as cushions on which it may rest its great weight without abrading the skin. These callosities are not formed, as some have imagined, by the constant kneeling to which the Camel is subjected, but are born with it, though of course less developed than they are after they have been hardened by frequent pressure against the hot sand.
