more ancient weapons were found on the hill-sides, 
in places where the river cuts into the plateau. 
The site where I picked up the largest number 
had been buried to a depth of seven or eight feet ; 
only where the water after heavy rains had washed 
great masses of sand and gravel away, the arrow- 
heads, with other weapons and implements, had 
been exposed. These deeply-buried settlements
