2/0 IN AUTUMN. 



ing that the relics of two peoples had been left 

 upon a tract of some two hundred acres ? First, 

 the tract was deforested, which would lead to 

 much disturbance of the surface soil ; secondly, 

 the stumps of the trees were uprooted, which 

 would lead to a greater disturbance ; and, lastly, 

 constant plowing, exposure of a raw surface to 

 winds and rain, and the erosion due to the flood- 

 ing of the stream that drained the tract, would 

 result inevitably in the moving of objects, as 

 small as arrow-points, to considerable distances 

 from where they were left in Indian or pre-Indian 

 times. It would be strange, indeed, if any evidence 

 of earlier and later occupancy had withstood such 

 vicissitudes ; and yet such was the case. The 

 highest ground afforded ninety per cent of the 

 specimens I was able to find, of argillite ; while 

 in the low-lying area of the one-time stream's 

 tortuous bed the argillite and jasper implements 

 were commingled, with a preponderance of jas- 

 per and quartz in the ratio of seven to two. It 

 was evident that the washing down of the high- 

 er ground and partial obliteration of the valley 

 had transported the argillite and mingled it with 

 the jasper, and not generally commingled and 

 brought to certain points the equally scattered 

 objects made of these minerals. During the 

 summer of 1887 a very careful and intelligent ob- 

 server reported to me that, in a field not far from
