484 Koons—Kettle-Holes of the Wood’s Holl Region. 
that flowing water made them, for often if they were made in 
this way the water must have found its way directly back into 
the face of the glacier if the lowest point is any indication as 
to the direction of the flow. 
We find kettle-holes also below sea-level. There is one in 
Great Harbor, at Wood’s Holl, nineteen fathoms deep with shal- 
low water all around; and it is said that it has been gradually 
filling within the memory of men. One in Vineyard Sound is 
forty fathoms deep with the water only ten on its borders. 
Professor Verrill also informs me of another off Cape Ann ninety 
fathoms deep while the water about is from thirty to forty. 
Upon conversing with the various naturalists of our United 
States Fish Commission corps who are familiar with the geo- 
logical features about Vineyard Sound, and more especially 
Professors Baird and Verrill, they express themselves very 
decidedly of the opinion that flowing water could not be the 
agency that made them. ‘The structure, arrangement, an 
all their features utterly preclude the idea.” Also Professor 
Linton, who has accompanied me each year in a part ol my 
studies, is of the same opinion. 
ere is one place between Wood’s Holl and Falmouth, 
however, where it is very evident that a stream did flow to the 
south from-among the hills, and the bed and sides of this are 
very different from the ordinary slopes and bottom of the 
kettle-holes. The former are almost paved with bowlders just as 
we should expect to find them in the bed of a stream flowing 
through such material as the glacial drift, while, as stated 
above, the kettle-holes are quite free from them. 2 
ere are also evidences two miles west of T'arpaulin Cove, 
on the south side of Naushon, that a glacial stream, of no mean 
proportion, swept from among the hills in the center of the 
island into Vineyard Sound. The exact windings of the 
stream are easily traced, and just to the west of its mouth strat- 
ified deposits are found cropping out in the bluff seventy-five 
_ feet above mean tide; but this river channel, unlike the one 
found on the mainland east of Wood’s Holl, has few bowlders 
in it because of the fineness of the material composing the 
west end of the island, and the notable absence usually. of 
large rock fragments especially at this point. 
Stratified deposits composed of clay and sand more or less 
fine are found in various other localities. Beyond Quisset 
Harbor nearly to the extreme northeast point visited, 4 finely 
laminated clay bed several feet in thickness and covering con- 
siderable area is found with no coarse material over it but 
large bowlders near by. At several points on the road 
between Wood’s Holl and Falmouth thin beds of stratified 
material are found, one of which dips at an angle of about
