440 Forty-second Report on the State Museum. 



collection. I am not able to give any conjecture as to the source 

 whence this chert was procured. 



The accompanying* sketch of Silver Lake and its surroundings shows 

 the localities to which reference has been made in the foregoing 

 pages. The flints which form the subject of this article were found 

 at A; B marks the spot on Mr. Chamberlain's farm where the other 

 deposit was found. All* the fields between A and B and for a con- 

 siderable distance down the outlet are plentifully strewn with flint 

 arrow-heads and the debris of arrow-head making. The land here is 

 dry and its proximity to the lake afforded excellent facilities for 

 hunting and fishing. Here too, was the most natural point for cross- 

 ing the outlet, the banks being hard and dry upon both sides. 



On the west side of the lake, near the spot marked C, there is evi- 

 dence of Indian residence. Arrow-heads are unusually plentiful; and 

 stone pestles with at least one stone mortar have also been found in 

 that field and in the one adjacent. Flint chips, the refuse of arrow-head 

 manufacture occur here in little piles, the relative position of which 

 is indicated by the dots near C. From the regularity of these chip- 

 heaps I conjecture that they mark the sites of wigwams where arrow- 

 heads were made. This settlement must have been several acres in 

 extent. 



Very respectfully, 



IRVING P. BISHOP. 



State Nobmal and Training School, Buffalo, N. Y., Nov. 6, 1888. 



* The diagram illustrating the position of these flints, in relation to Silver Lake, and 

 to the other points noticed in this paper, was not engraved in time for this report, but 

 will be given in the Report of the State Geologist for 1889.
