EVIDENCES OF GLACIAL ACTION IN CONNECTICUT. 201 



huge mass of granite should have resisted the pressure of a great 

 ice-sheet, and remained so prominently in place as part of a vein, 

 when such pressure and an accompanying movement and grind- 

 ing were sufficient to not only round off and obliterate everything 

 like angularity from the granite surface, but also remove or re- 

 duce down to a much lower level and over a large proximate area 

 the whole vast mass of rock on which the granite protuberance, 

 if it be a portion of a vein, must have been as it were originally 

 imbedded, is, as Prof. Crosby admits, a result not a little singular. 

 There is certainly nothing analogous to such a phenomenon in 

 the vicinity, and it may well be questioned whether there is any- 

 thing similar anywhere. 



Furthermore, as throwing some light on this subject, there are, 

 as before stated, in comparative proximity to the " Sheegan " 

 Rock, a large number of undoubted bowlders of .the same granite, 

 which, though not comparable as regards size, may yet be regarded 

 as extraordinary, and as clearly involving the exercise of an enor- 

 mous disrupting and transporting power within a rather limited 

 area. One of these bowlders in the same township of Montville, 

 which is also an object of public curiosity, and known as the 

 " Goal " Rock, is, according to measurements made for the writer, 

 twenty-one feet high, twenty-five long, and twenty-five thick. 

 Another, in the vicinity of Gardner's Lake, from which nearly 

 one fourth of the original mass has been detached in fragments, 

 is reported as eighteen feet six inches high, thirty-five feet long, 

 and twenty feet thick. A third, on the east side of the Thames 

 River, in the town of Preston, is fourteen feet high, twenty feet 

 long, and seventeen feet thick ; and at least three or four others 

 in the same region, of similar dimensions, might be enumerated. 

 Above a mile east of " Allen's Point," and on one of the highest 

 of the elevations bordering the river, an area of several acres is 

 so covered with huge bowlders that in places it is difficult to find 

 a path through them ; while the -southern slope of the same ele- 

 vation, not far removed, is so strewed with such a multitude of 

 rounded, small bowlders that they have the appearance of having 

 been planted artificially. 



Fig. 5 represents an extremely picturesque though not a very 

 large bowlder, on the road between Norwich and Taftville, on the 

 lands of the Ponemah Manufacturing Company, and almost in the 

 center of the village that has within a comparatively few years 

 grown up about it ; and which, most fortunately, has thus far been 

 carefully protected by the company against the Vandalic spirit 

 which is so often prompted to mutilate or destroy everything in 

 the nature of a public curiosity.
