Xo other local material is suitable for flaking into im-plements, for Chalk-flints are rare here and seldom occur in bigpieces, while the granite, elvan, and slates are unworkable. Thegreenstone found in the neighbourhood is an extremely-tough rock,difficult to trim : but, though it is so suitable for hammer-stones,we found only one or two small pieces of it in the black , like the slate, were much decayed, and apparently had notbeen used.

[Photographed natural size.] The quantity of charcoal observed, and the number of hearthsfound (six or seven) were surprising ; but this bay must have beena particularly-favourable locality for occupation.
