SCIENTIFIC SURVEY. 359 



that of western Cauquomgomoc. We discovered no schists in 

 connection with these rocks. At Chesuncook lake we entered 

 upon a field already explored by yourself, hence the necessity of 

 my reporting further had ceased. 



Allow me, sir, in conclusion to say, that these observations were 

 conducted under a degree of personal discomfort which prevented 

 such an accurate and detailed examination of some of the more 

 interesting and obscure points as I could have wished, yet what 

 has been done is herewith submitted. 



With the greatest respect, 



Yours, &c.,

To Pbof. C. H. Hitchcock, Geologist 



of the Scientific Survey of Maine : 



Sir: — In accordance with an agreement that during an explora- 

 tion of a portion of Aroostook county in pursuit of such of the 

 vertebrated animals as I might find, any incidental observations I 

 might make in geology should be communicated to you, I here- 

 with submit the following for your consideration. 



I left Bangor in company with S. D. Besse of Winthrop, on the 

 evening of 29th of May. 



My route from Bangor was by railroad and steamboat to Matta- 

 wamkeag, thence up the Aroostook road to Patten, which was 

 made a station or central point of action. 



Quartz Boulders. 

 While passing along the northern part of No. 2 (Benedicta) and 

 southern part of No. 3, my attention was drawn to the abundance 

 of quartz boulders of a larger size than that rock generally exhib- 

 its, or, at least, much larger than any I have met with in Maine. 

 These boulders have evidently been swept from some localities fur- 

 ther north, (perhaps Chase's mountain,) where they were associated 

 with schist of a talcose type, patches of which still adhere to them. 

 From what exact locality they did start, or whether, like the quartz 

 and talcose schists in other parts of the Union, they indicate the 

 presence of gold, I am not able to say, as I made no examination 

 of them in reference to that or any other specific character.
