In addition to the stone tools, picks of deer horn were employed for quarrying the chalk when making the foundations of the uprights. Those who are familiar with the antlers of the deer, will recall the sharp pointed tine, known as the "brow tine," which projects forward from the horn above its core or socket. This was the tooth of the pick, all other tines being sawn off; thus transforming the antler into a very rough implement closely resembling a pick, with a single point. Many splinters from these picks were found actually embedded in the chalk of the foundations, and one entire discarded example was discovered showing great signs of use, the brow tine being worn away to a considerable extent. DRESSING THE STONES There can be little doubt that the Sarsens were first of all roughly hewn into shape, before they were conveyed to the site. It stands to reason that a primitive race, when faced with the problem of transporting a vast mass of stone, would first of all reduce its bulk to the approximate proportions which it would have when finished and erected. Moreover, the chippings and mason's waste discovered in the excavations of 1901 reveal comparatively little Sarsen stone, and only a few large fragments, such as must have been broken off in finally reducing the "Grey Wethers" to monolithic pillars and lintels. It must not be forgotten either, that the Sarsens occur naturally in tabular blocks, well adapted to the purpose of the builders. The surface of these blocks is often soft, and sugary, while the body of the stone is dense. The nature of their composition is such that no two stones are quite alike in hardness, some can be disintegrated easily, even with the fingers, while others are dense, and will resist blows with a hammer and chisel. But in any case the natural structure of the stone made it an ideal material for the Trilithons, or, it may be, that the Trilithons were the natural outcome of the physical peculiarities of the rock. The preliminary dressing may very possibly have been effected by lighting small fires along the proposed line of fracture, and heating the stone, and then by pouring cold water upon it, which would originate a cleavage in the grain, which would readily break away under blows from the heavy mauls referred to in Class V. of the Implements. Sides and ends could thus be roughly squared. The next point was the transportation of the rough ashlar to the site. Here the problem is not so formidable as it appears, when it is remembered that time was no object to the builders, that labour was abundant, and that in all probability the work was undertaken under the stimulus of religion.
