by this time have been added to these reservations; and with any- 

 thing like an appreciative response, there would before this have 

 been annexed to the State Museum the remarkable Aboriginal 

 Flint Quarries which have been described elsewhere in this report 

 by the archeologist. 



A special examination by W. Goldring, of the Pleistocene or 

 Postglacial fossils in the Lake Champlain and St Lawrence valley 

 clays, has led to the noteworthy conclusion that the changes in 

 these faunas southward from the St Lawrence area through the 

 Lake Champlain area indicate a gradual freshening of the sea in 

 that direction. The discussion of this interesting evidence is set 

 forth in a paper appended to this report.
