EVIDENCES OF GLACIAL ACTION IN CONNECTICUT. 199 



measurements by Prof. Crosby, of the Boston Society of Natural 

 History, are as follows : northwest side, forty-six feet ; northeast, 

 fifty-eight ; southeast, forty-five ; southwest, seventy. Maximum 

 height, reckoning from the lower or down-hill side, to the highest 

 point on the upper side, approximately, sixty feet ; approximate 

 cubic contents, seventy thousand cubic feet ; approximate weight, 

 about six thousand tons. Other and former reported measure- 

 ments of this rock indicate much larger dimensions than those 

 reported by Prof. Crosby ; and, although the determinations of 

 an expert observer like the latter are entitled to the greatest 

 confidence, it is nevertheless true that the form of the rock is so 

 irregular as to render an exact estimate of its size, cubical con- 

 tents, and weight a matter of no little difficulty. Figs. 3 and 4 

 give an idea of the position, size, and appearance of the " Sheegan " 

 Eock, as seen from the valley beneath it, looking west. The intro- 

 duction into the picture of the horse and wagon beneath the rock 

 affords in some degree a standard for estimating its height. The 

 cavity or recess beneath the rock, which is said to have been 

 occupied, at the time of the first settlement of the country, by a

Mohegan Indian (from whom the rock undoubtedly derived its 

 name) as a dwelling-place, is sufficiently capacious to admit of 

 being used as a place of shelter for the sleds and other farm 

 implements of the farmer proprietor. A rude ladder on the 

 southern side of the rock affords facilities for reaching its top 

 and obtaining a somewhat extensive view of the surrounding 

 country.
