In the summer of 1854, when civilisation had made very slight inroads on the western wilderness, I visited a group of Chippewa lodges on the south-west shore of Lake Superior, where they still maintained many of their genuine habits. Their aged chief, Buffalo, was a fine specimen of the uncorrupted savage, dressed in native attire, and wearing the collar of grizzly bear’s claws as proof of his triumph over the fiercest object of the chase. Their weapons were partly of iron, derived from the traders. But they had also their stone-tipped arrows; and one Indian was an object of interest to a group of Indian boys as he busied himself in fashioning a water-worn pebble into an edged tool. He held an oval pebble between the finger and thumb, and used it with quick strokes as a hammer. But he was only engaged on the first rough process, and I did not see the completion of his work. No doubt, the leisure of all was turned more or less to account in supplying themselves with their ordinary weapons and missiles. But Catlin’s free intercourse with the wild western tribes familiarised him with the regular sources of general supply. “The best flakes,” he said, “outside of the homemade, were a subject of commerce, and came from certain localities where the chert of the best quality was quarried in sheets or blocks, as it occurs in almost continuous seams in the intercalated limestones of the coal measures. These seams are mostly cracked or broken into blocks that show the nature of the cross fracture, which is taken advantage of by the operators, who seemed to have reduced the art of flaking to almost an absolute science, with division of labour; one set of men being expert in quarrying and selecting the stone, others in preparing the blocks for the flakers.”[38] But suitable and specially prized material were sometimes sought on different sites, and disseminated from them by the primitive trader. Along eastern Labrador and in Newfoundland arrow heads are mostly fashioned out of a peculiar light-gray translucent quartzite. Dr. Bell informs me that near Chimo, south of Ungava Bay, is a spot resorted to by the Indians from time immemorial for this favourite material; and arrows made of it are not uncommon even in Nova Scotia. Among the tribes remote from the sea coast, where no exposed rock furnished available material for the manufacture of their stone implements, the chief source of supply was the larger pebbles of the river beds. From these the most suitable stones were carefully selected, and often carried great distances. Those most easily worked into flakes for small arrow heads are chalcedony, jasper, agate, and quartz; and the finer specimens of such weapons are now greatly prized by collectors. The coast tribes both of the Atlantic and the Pacific found similar sources of supply of the stones best suited for their implements in the rolled gravel of the beach, and this appears to have been the most
