14/47 We left our horses at the entrance, and spent an hour or two in hunting the place over. The ground was covered with pieces of obsidian knives and arrow-heads, and fragments of what seemed to have been larger tools or weapons; and we found numbers of hammer-heads, large and small, mostly made of greenstone, some whole, but most broken. Solid hammers belong to the earliest period. They are made of longish rolled pebbles; some are shaped a little artificially, and are grooved round to hold the handle, which was a flexible twig bent double and with the two ends tied together, so as to keep the stone head in its place. The hammers of a later period of the "stone age" are shaped more like the iron ones our smiths use at the present day, and they have a hole bored in the middle for the handle. |
