The whole tract of country, on either side of our line of march, was one continued jungle, and as level as a bowling-green. The force under the personal command of Colonel Campbell, exclusive of officers, amounted at this time to 2,833 men, with twelve iron twelve-pounders, each drawn by an elephant. Brass guns of this description are usually drawn by ten, or even twelve, bullocks; brass eighteen-pounders by fourteen bullocks; and brass twenty-four-pounders by eighteen bullocks. An iron twenty-four-pounder is drawn by twenty-six bullocks; an iron eighteen-pounder by twenty-two bullocks; and an iron twelve-pounder by eighteen bullocks. Singly, therefore, that noble animal, the elephant, will draw a gun for which ten or even more bullocks are allowed. These and the following remarks regarding cattle, are given for the purpose of showing the number used in dragging guns and carrying loads. By the regulations of the service in Bengal, it is directed that no elephant shall be taken into the service under twelve years of age, nor under seven feet in height. A committee is appointed to examine and report whether the animals are fit for service; but it not unfrequently happens that infantry or cavalry officers, or both, are put upon these committees, who know nothing at all of the matter. Sometimes, however, the animals are so palpably inefficient and diseased, that, as one of the committee-officers exclaimed, "This camel speaks for itself." No elephant is employed unless the committee can report that he is capable of carrying at least 20 maunds of 80 sicca weight, or 1,600 pounds = 14 cwt. 32 lbs. Camels admitted into the service by a committee, must never be under five, nor more than nine, years old; and capable of carrying a load of at least 6 maunds, or 480 lbs. Bullocks are admitted into the service not under five, nor above eight, years of age. Draught-bullocks must be fifty inches in height; those for carriage, not under forty-eight inches. The former must be capable of carrying 210 lbs. avoirdupoise weight, besides the gear. The comparative value of these animals will be seen by the following scale:-- An elephant carries 1,600 lbs. A camel " 480 " A bullock " 210 " In wet weather a camel, which, in dry weather, carries six maunds of tents, etc., will carry only four maunds, one-third being allowed for the difficulty which the camel finds of keeping on his legs in wet ground.
