Art. XXX.—Upon the Kettle-Holes near Wood's Holl, Mass. ; 
by Professor B. F. Koons. 
In the study of the glacial phenomena about Wood’s Holl, 
Mass., I have gathered many facts concerning the Kettle-Holes 
of the region as to depth, size, direction of the longer axis, 
their groupings, and other points, which may throw light upon 
their origin. No special study of them as regards some of 
these points had been made, and, therefore, without previous 
convictions as to what conclusion the facts would lead, 1 deter- 
mined during the last summer to give them a careful examina- 
tion as far as my work in connection with the United States 
Fish Commission at Wood’s Holl would allow. Professor War- 
ren Upham, who has made many observations on the terminal 
moraine along southern New England and the adjoining islands, 
regards the deposits as a part of that terminal moraine, and 
others hold the same opinion. There is perhaps no more re 
-markable region on the whole line than the vicinity of Wood's 
Holl, both over the point of the main-land, and on the adjoining 
eastern islands, Uncatina, Nonamesset, and Naushon, of the 
Elizabeth group, which extend southwestward between Buz- 
zard’s Bay on the north and Vineyard Sound and the ocean on 
the south. The trend of this group of islands is north 60° east. 
The hills are masses of earth, sand, gravel and bowlders tum- 
bled together in the greatest confusion. In places the surface 
is well covered with granite and gneiss bowlders, some 0 
gigantic size, as will be seen by reference to table No. 2. 
The theory that this isa part of the terminal moraine, seems 
- i when the country is viewed from some of the high 
ills a mile or two to the east of Wood's Holl. To the south 
west stretches away the long line of islands; and to the north- 
zard’s Bay and Vineyard Sound, where the land is not mor 
than three-fourths of a mile wide. One of these localities of
