 to his rude stone tomahawk, many years before the coming of the 

 pale-faces. 



At these places the beach is thickly strewn with flint chippings 

 and, frequently, the sand or gravel contains large quantities of 

 them to a considerable depth. This flint, which is very dark, is 

 identical both in colour and character with that contained in the 

 Trenton formation at Hull, from whence it was doubtless procured, 

 as it is there found in large quantities and may be removed from 

 the limestone beds with little difficulty. The fact that flint is not 

 found in the Chazy or Calciferous rocks, outcropping on the lake 

 front, would seem to justify the presumption that the Algonkin 

 warriors of Lake Deschenes procured their supply of raw material 

 from the nearest and most convenient source, which would be the 

 place already indicated. 



While these work places contain such traces of palceolithic 

 art in great abundance, they also reveal evidences of later contact 

 with the white man in the shape of light colored gun and musket 

 flints which are said to be characteristic of the Cretaceous flint of 

 western Europe. 



At Bell's Bay, just below Aylmer, I removed several fragments 

 of worked flint from beneath a large oak stump and about one foot 

 below its base. These were taken from a bed of river gravel that 

 was being washed away, at high water, by successive spring 

 floods. Similar fragments were also obtained from the surface of 

 the same gravel bed, having been laid bare by the washing away 

 of the overlying deposit of vegetable mould. As, in the former 

 instance, the flints must have become embedded in the gravel long 

 before the time required for the oak to grow from a seedling to a 

 large forest tree, it is not difficult to form an approximate estimate 

 of the long period of time which must have intervened between 

 the days in which the first and the last of these fragments were 

 cast aside by the lithal artificer. 



At Raymond's Point, on the side next the big bay, some 

 recent quarrying operations have exposed a fine section of strati- 

 fied rock, with an overlying bed of coarse gravel about i8 inches 

 in thickness. I secured a piece of flint from the bottom of this 

 gravel, where it came in contact with the bed of rock beneath. It
