but, where water can be had, they should be watered daily. The load of the camel varies from 300 to 450 pounds, depending upon its condition. It is admirably adapted for carrying long articles, as ladders, tent-poles, and even light mountain guns. The marching power of camels depends on a number of conditions. They are good goers in loose sandy soil, and even over stony ground, if the stones are not too large and sharp; in slippery places they are useless, as they have no hold with their feet. They are very enduring, making the longest marches at an average speed of two miles an hour, and can ford deep rivers with ease if the current is not too rapid. When the bottom of the ford is shifting sand, the passage of a number of camels renders it firm. A string of 500 camels covers about one mile of road; 1,250 mules, carrying the same weight of supplies, occupy double the distance. Camels must be unladen at ferries. For military purposes these animals are purchased between the ages of five and nine years, and may be used up to the age of sixteen. They average about one thousand pounds in weight, seven feet in height to the top of the hump, and eight feet in length from nose to tail. In camp and when not at work they are arranged in lines facing each other, or in circles heads inward; the latter plan is the favorite formation at night. The allowance of spare camels on service is ten per cent. [Illustration: An Afghan Post-Chaise; Going to the Front. ] Lieut. Martin, R. E., states that his company, of Sappers and Miners, was able to get an exceptional percentage of labor from the camels under his charge by attention to certain details; and says further, that "camels are very quarrelsome and bite each other badly when grazing. They can ford four feet of moderately running water, easily, if the bed is good; but a yard of greasy mud, a few inches deep, will throw many camels and delay a convoy for hours. Camel-bridges were carried on the leading camels, with a few shovels and picks, in every convoy of the Kandahar Field Force, and all small cuts or obstructions were thus bridged in a few minutes; the camels remaining by their bridges (two gang-boards eight by three feet) until the last baggage camel had passed. In perfectly open country, such as Kandahar to Girishk, it was found possible to march the camels on a broad front, the whole convoy being a rough square; camels starting at 3 A.M. have been known to arrive at camp ten miles off as late as 5 P.M."
