From time to time fresh disclosures prove the extent to which such systematic industry was carried on. The various collections thus brought to light were unquestionably the result of prolonged labour, and were, for the most part, undoubtedly stored for purposes of trade. In some cases they may have been accumulated in the arsenal of the tribe in readiness for war. But whether we recognise in such discoveries the store of the trader, or the military arsenal, they indicate ideas of provident foresight altogether distinct from the desultory labours of the Indian savage in the preparation of his own indispensable supply of implements for the chase or for war.
But there were also, no doubt, home-made weapons and implements, fashioned with patient industry out of the large rolled serpentine, chalcedony, jasper, and agate pebbles, gathered from the sea coast and river beds, or picked up wherever they chanced to occur. When camping out on the Neepigon river, with Indian guides from the Saskatchewan, I observed them carefully collecting pieces of a metamorphic rock, underlying the syenite cliffs, which, I learned from one of them, was specially adapted for pipes. This they would carry a distance of fully 800 miles before reaching their lodges on the prairie. Dr. Robert Bell described to me a pipe made of fine green serpentine, of a favourite Chipewyan pattern, which he saw in the possession of an Indian on Nelson river. Its owner resisted all attempts to induce him to part with it, assigning as a reason of its special value that it had been brought from Reindeer Lake distant several hundred miles north of Frog Portage, on Churchill river. The diverse forms in which various tribes shape the tobacco pipe are highly characteristic. In some cases this is partly due to the texture and degrees of hardness of the material employed; but the recovery of pipes of nearly all the very diverse tribal patterns, made from the beautiful catlinite, or red pipestone of the Couteau des Prairies, leaves little room for doubt that the stone was transported in rough blocks and bartered by its quarriers to distant tribes. This flesh-coloured rock has suggested the Sioux legend of its origin in the flesh of the antediluvian red men, who perished there in the great deluge. It is soft, of fine texture, and easily wrought into minutely varied forms of Indian art, and so was coveted by the pipe-makers of widely severed tribes. Hence red pipestone pipes of many ingenious forms of sculpture have been recovered from grave mounds down the Mississippi, eastward to the Atlantic seaboard, and westward beyond the Rocky Mountains. This prized material appears to have circulated among all the Plain tribes. Pipes made of it were to be found in recent years preserved as cherished possessions among both the Sioux and the Blackfoot tribes. Dr. George M. Dawson found in 1874 part of an ancient catlinite pipe on Pyramid Creek, about lat. 49°, long. 105°.
