USEFULLY CLEVER ELEPHANTS. 99 ellers tell us that some of them are as careful about the neatness of their work as men could be! An elephant was once seen to step back a few yards, as if to see whether it had laid a block of stone straight, and then, apparently not satisfied, it returned and pushed it into its right place ! Some years ago, an engineer in Ceylon had to lay pipes to convey water nearly two miles, over hills and through woods where there were no roads. To help him in his work, he had to employ several elephants; and nothing could be more interesting than to watch the way in which the ele- phant engineers did their work. Lifting up one of the heavy pieces of pipe, and balancing it with his trunk, each animal would march off with its load, and carry it safely over every obstacle, to the place where it was to be laid.
