MODIFIED DRIFT ALONG CONNECTICUT RIVER. 5 
In Putney, Dummerston, and Brattleborough, opposite the foregoing, 
we find nearly the same normal limit of the modified drift, and increased 
height of that brought in by tributaries. A bend of the river at the 
north-east corner of Putney gives to that town a notable expanse of 
low terrace, covering three fourths of a square mile. Many of the ter- 
races in Dummerston, especially for two miles north from the depot, 
slope more than is common towards the river, and are less distinctly 
separated by the usual steep escarpment. An interesting remnant of the 
kame occurs a third of a mile south-west from the depot (p. 48). At the 
west side of this ridge is a hollow of 100 feet, beyond which is an exten- 
sive deposit of kame-like gravel, which has been protected from erosion 
by a border of ledges on its south-east side. This has about the same 
height with the top of the kame, and appears to be of similar origin. 
Two large streams—West river and Whetstone brook—join the Con- 
necticut in Brattleborough. The latter flows through the centre of the 
village, supplying valuable water-power. A large part of its delta remains 
in the high plain at the south and south-west. The height of this a mile 
west of the river is 425 feet above the sea; at the Catholic cemetery, 
409; at the fair-ground, about 400. Above the west part of this plain, 
however, a still higher delta, at 490 feet, has been formed by a small trib- 
utary of this brook. This is the highest deposit of modified drift found 
in this valley south of Bellows Falls. The height of Connecticut river 
here is 200 feet above the sea. In the north-west part of Brattleborough 
village there rises a ledgy hill, about 525 feet above the sea, below which 
on the west is a belt of alluvium, extending north from the delta of Whet- 
stone brook to the valley of West river. Its northward slope shows it to 
be a part of the delta deposit of this brook. In the village erosion has 
removed the delta, giving on the north three principal terraces, 290, 308, 
and 341, and on the south two, 300 and 369, feet above the sea. 
West river is situated one mile farther north, and is larger than Whet- 
stone brook ; but it is of less interest, because it forms an exception to 
a general rule, having apparently brought no delta into the Connecticut 
valley. It has, however, labored so abundantly in hollowing out its chan- 
nel, that its course is through a beautiful basin, somewhat like that on 
Saxton’s river, mainly overflowed at high water and bordered by terraces, 
On the north side of its mouth are the most southern remnants of the
