EEMAKKS BY PUTNAM, ABBOTT AND MORSE. 37 



of the eggs of the canker worm and other insects in win- 

 ter ; and then taking the snow and ice as his special sub- 

 ject, he gave an account of the formation of glaciers, the 

 moraines and glacial currents, and the great results of the 

 glacial action on the surface of New England. The 

 movements of the glaciers were accurately described, 

 trending from north to south, as showing the immense 

 distances over which bodies taken up in the glacial drift 

 are carried. 



In closing, Prof. Morse alluded to the existence of 

 man during the glacial period, and the important dis- 

 covery made by Dr. C. C. Abbott of Trenton, N. J., of 

 stone implements in the gravel at Trenton. 



In response to the call of the chairman, Dr. C. C. 

 Abbott, who was present by invitation, gave a brief 

 notice of the discovery of the chipped-stone implements 

 in the gravel, and the condition under which they were 

 found. 



He said this was his first field meeting, and it was 

 evident that a winter field meeting could be carried on as 

 successfully as a summer one, and he was very glad to be 

 present. 



The chairman alluded to the very recent discovery at 

 AYakefield, Mass., of chipped-stone implements of the 

 same character as those found in the Trenton gravel, and 

 of the great probability of their discovery, in place in 

 the gravel, and called upon the members of the Institute 

 to look with care at every cut through a gravel hill, with 

 the anticipation of making the important discovery of a 

 palaeolithic implement. 



He then called upon Mr. John Robinson of Salem, the 

 botanist of the Institute.
