A trench of about 200 feet in length, 15 feet wide, and in some places 20 feet deep, having been duly made through which the bull might proceed on the rollers to the edge of the mound—this course was necessary owing to the impossibility of lifting such a massive weight—the giant animal was slowly pulled by a large number of Arabs to the end of the trench and down the slope of the mound, where it was lowered on to a specially-constructed cart, which had been a nine days’ wonder to the natives ever since its appearance. The cart itself was fitted with two strong axles which had been used by Botta in the removal of sculptures from Khorsabad. “Each wheel was formed of three solid pieces, nearly a foot thick, from the trunk of a mulberry tree, bound together by iron hoops. Across the axles were laid three beams, and above them several cross-beams, all of the same wood. A pole was fixed to one axle to which were also attached iron rings for ropes to enable men as well as buffaloes to draw the cart. The wheels were provided with movable hooks for the same purpose.” The mulberry wood used had of course to be procured in the mountains, there being no wood of the required substance or size in the Mesopotamian valley. Buffaloes were first harnessed to the pole, while a number of men tugged at the ropes attached to the wheels and the movable hooks, but the buffaloes appear to have soon struck, and they were consequently taken out, the whole of the work now being done by three hundred Arabs. At length, after multitudinous efforts, the bull arrived at the river where it was landed on a specially-prepared platform from which it might slide on to a raft. Thus much for the obstacles to be surmounted in the mere removal of these enormous blocks of stone by an excavator of the nineteenth century, from which we may form a small and very inadequate estimate of the indomitable zeal and invincible energy of the Assyrians some twenty-six or twenty-seven centuries ago in quarrying, carving, transporting and fixing the guardian genii. _PLATE III_ [Illustration: _From Layard_ EXCAVATIONS AT NIMRÛD (CALAH) IN ASHUR-NAṢIR-PAL’S PALACE]
