264 BOARD OF AGRICULTURE. 



The general dip is north-westerly, and the curve is crowded be- 

 tween the highly inclined strata, and is rendered a sharp curve in 

 consequence of the great pressure to which it was formerly sub- 

 jected. We mention it particularly as it is exposed in a favorable 

 locality for inspection by those who are interested in viewing how 

 .the forces of Nature have operated. We intended to have meas- 

 ured very carefully the dip, thickness and precise mineral character 

 of every layer that is exposed along the shore in Belfast, but time 

 prevented. It is the most favorable place for such measurements 

 we have seen among any of the Taconic schists. The careful 

 measurements should extend to the older gneiss in Waldo. 



7. Alluvium. 



Quite a number of observations were made among the alluvial 

 rocks and markings in this region ; but as we have thought it best 

 to group together under Surface Geology, our descriptions of allu- 

 vial phenomena from every portion of the State, we will therefore 

 refer to that heading for the description of the alluvium of the 

 country about Penobscot bay. 



Mr. George L. Goodalc spent a few days, at our request, in 

 Vinalhaven, and we now present his description of the rocks there 

 seen. We suppose these rocks, with those of North Haven and 

 Islesborough, to be entirely Taconic, and to belong to the schists, 

 or the upper portion of the series. 



To C. n. Hitchcock, A. M. : 



Dear Sir : — In accordance with your wishes, I visited the Fox 

 islands in Penobscot bay during the early days of July. Owing 

 to limited time I was unable to make the examination as thorough 

 as I could have desired. But through my friend Dr. Delaski, who 

 has studied carefully the geology of this neighborhood during his 

 residence of several years at Carver's Harbor, I was enabled to pur- 

 sue my investigations to better advantage than would have been 

 possible in the case of a perfect stranger. Dr. Delaski has paid 

 particular attention to the records of the drift phenomena at Vinal- 

 haven, and ho has kindly promised to furnish a detailed account of 

 his views upon this highly interesting, and, ^s yet, obscure subject. 



Although his opinions may differ materially from those entertained 

 by the Geologist of the Survey, I am sure they will be received 

 with pleasure as coming from one whose observations are acute 

 and accurate.
