At an epoch which, though still prehistoric, is modern when compared with the latest traces of post-glacial or cave periods, the worked flints and implements of bone, found in many European primitive deposits, in caverns, chambered cairns, barrows, and among the chance disclosures of the agriculturist, continue to exhibit the most infantile stage of rudimentary art. Fragments of sun-baked urns, and rounded slabs of slate of a plate-like form, are associated with indications of rude culinary practices, illustrative of the habits and tastes of savage man. Broken pottery, calcined bones, charcoal ashes, and other traces of cooking operations, have been noted under similar circumstances, alike in England and on the continent of Europe; showing where the hearth of the Allophylian had stood. Along with those, in Kent’s cavern especially, the flints lay dispersed in all conditions, from the rounded mass as it came out of the chalk, through various stages of progress, on to finished arrow-heads and hatchets; while small flint-chips, and partially used flint-blocks, thickly scattered through the soil, served to indicate that the British troglodyte had there his workshop, as well as his kitchen, and wrought the raw material of that primitive stone-period into the requisite tools and weapons of the chase. Nor were indications wanting of the specific food of man in the remote era thus recalled for us. Besides accumulated bones, shells of the mussel, limpet, and oyster, lay heaped together near the mouth of the cave, along with a palate of the scarus: indicating that the aborigines found their precarious subsistence from the products of the chase and the spoils of the neighbouring sea. The same fact is further illustrated by similar relics of a subterranean stone dwelling at Saverock, near Kirkwall, in Orkney, situated, like the natural caverns of Torbay, close to the sea-shore. Accumulated remains of charcoal and peat ashes lay intermingled with bones of the small northern sheep, the horse, ox, deer, and whale, and also with some rude implements illustrative of primitive Orcadian arts; while a layer of shells of the oyster, escallop, and periwinkle, the common whelk, the purpura, and the limpet, covered the floor and the adjacent ground, in some places half a foot deep.
