A fourth excavation, known as Excavation Q, yielded at a depth of three feet six inches to four feet six inches, ten flint axes, one sandstone axe, nine edged flint hammer-stones, four rounded flint hammer-stones, ten Sarsen hammers, and seven mauls, weighing from thirty-six to fifty-eight and a half pounds. Large numbers of deer's horn splinters were discovered in this excavation. _Excavation V._ (Eight feet deep.)--Four axes of flint, one of Sarsen, three edged hammer-stones of flint, one Sarsen and one Diabase hammer-stone, were found at depths varying between two feet and four feet. One Sarsen hammer-stone was found under the base of the foreign upright, which stands in front of the upright monolith of the Great Trilithon, at a depth of six feet below datum. In this last excavation, at a depth of about seven feet, the slab of tooled Sarsen already referred to was discovered, and on it a very small stain of copper carbonate. The depth at which this stone was discovered precludes the possibility of metal being thus sunk by moles or rabbits. This list, like the details of the foreign stones, may not be of general interest, but it affords a very powerful argument for the date of the structure. To summarise the "finds." The metal objects found consist of various coins ranging from Roman to recent times, about half a dozen in number, all coming from the surface, and none at a greater depth than ten inches. In other words, they may be classed as "superficial" finds, of very little value; the more so, as some of the more recent coins were found at a greater depth than those of earlier date. The only other trace of metal is the small green stain upon the slab of Sarsen already alluded to. This stain can only have been caused by the contact with the stone of a small fragment of copper, which appears to have been entirely decomposed, as no traces of it could be found. It must have been very minute, since had it exceeded one-eighth of an inch, it could not have escaped the mesh of the sieve employed in searching for it. Clearly, therefore, it could not have been an implement; perhaps it was an ornament. On the other hand, the Stone Implements discovered number one hundred and fifteen, and were found scattered through the excavations at all depths, and even under the foundations of one of the foreign stones. Probably the entire area of Stonehenge, if opened up, would yield over seven thousand examples.
