The Rev. G. S. Robinson, of Scottsville, exhibited several 

 curious tablets and other relics stated to have been found in ancient 

 mounds in Michigan. The specimens gave rise to considerable dis- 

 cussion as to their genuineness and antiquity. 



Mr. E. P. Clapp, of North Rush, exhibited a pipe found in 

 excavation at Scottsville. The front of the bowl was ornamented 

 with a human head, not of Indian type, and above the back oi the 

 bowl was the head of an animal, suggesting a wildcat.
