Excerpt: ...TENONS AND MORTICES The trilithons of the outer circle were each provided with "two tenons worked on its apex, to bear the two lintels or horizontal stones which rested upon it." Figure 83 shows the construction of these trilithons, with their tenons and mortices. Those of the Horseshoe were provided with but one tenon each, as is shown in figure 84.

The tall single upright pillar in figure 79, shows one of these tenons very plainly and vestiges of them are plainly visible in figure 80. Corresponding mortices were sunk into the lintels to admit the tenons. Fig. 85.--Flint axes used in dressing the stones used in the building of Stonchcnge. Drawing by the author.

These black flint axes are chipped to an edge on one side and are flat on the other. This class of tool, shown in figure 85, was used in dressing the stones at Stonehenge. A small copper stain found, seven feet below the surface of tht ground, on one of the stones, is the only evidence that bronze may have been known to its builders. Of course, the use of bronze...
