frequent resort of the Micmacs and other tribes of the Canadian Maritime Provinces. I have already referred to information derived from Dr. G. M. Dawson and Dr. Robert Bell, to both of whom I have been indebted for interesting results of their own personal observations as members of the Canadian Geological Survey. Collectors are familiar with the elongated flat stones, with two or more holes bored through them, variously styled gorgets, implements for fashioning sinew into cord, etc. They are made of a grayish-green clay slate, with dark streaks; and the same material is used in the manufacture of personal ornaments, ceremonial objects, and occasionally for smooth spear heads and knives. Relics fashioned of this peculiar clay slate are found throughout Ontario, from Lakes Huron and Erie to the Ottawa valley. A somewhat similar stone occurs in situ at various points, but Dr. Bell believes he has satisfactorily identified the ancient quarry at the outlet of Lake Temagamic, nearly 100 miles north of Lake Nipissing. No clay slate procured from any other locality corresponds so exactly to the favourite material. The site is accessible by more than one canoe route; and quantities of the rock from different beds lie broken up in blocks of a size ready for transportation. Dr. Bell found on the shore of Lake Temissaming a large unfinished spear head, chipped out of this clay slate, and ready for grinding. When the region is settled and the land cleared, sites will probably be discovered where the aboriginal exporters reduced the rough blocks to forms convenient for transport. Dr. Bell has described to me specimens of narrow and somewhat long spear points, of local manufacture, made from smoky chert found on or near the Athabaska, in Mackenzie river basin; and an arrow head of brown flint from the mouth of Churchill river, Hudson Bay. The flint implements of Rainy river and Lake of the Woods are of brownish flint and chert, such as are found in the drift all over the region to the south-westward of Hudson Bay; and are mostly derived from the Devonian rocks. Worn pebbles of this kind occur in the drift as far south as Lake Superior. A branch of Kinogami river is called by the Indians Flint river (_Pewona sipi_) from the abundance of the favourite material they find in the river gravel and shingle. The finest flint implements of Canada are those of the north shore of Lake Huron, made from material corresponding to a very fine-grained quartzite, approximating to chalcedony, found among the Huronian rocks of that region.
