Nook’s Hill, frequently named in this connection and of Revo- 
lutionary War fame, has been levelled. It formerly covered the 
ground included between Dorchester Avenue, First, D, and Fourth 
Streets, and was made up of lower till, like the other lenticular 
hills of this vicinity. 
The outcrop of slate south-east of F, along and in an empty 
lot south of West Third Street, mentioned by a member of the 
Society, Feb. 3, 1875, at the discussion which followed the reading 
of a paper on local geology, gives the data needed to determine 
the relations of the rocks at the various localities named, to wit, 
strike N. 93° E.-S. 93° W. ; dip, North 42° to 52°. This outcrop 
is above the 30-foot contour line. 
For three-eighths of a mile northward from the slates which 
Professor Shaler has described from their exposure in the bed of 
and near Chestnut Hill reservoir, in Brighton, is puddingstone, 
everywhere showing at the surface, from the Newton line to Co- 
rey’s Hill. The hills of this rftck rise to the heighth of some 200 
feet. The rock is quarried on Chestnut Hill Avenue and on How- 
ard Place, south of Union Street. It is largely jointed. The 
noticeable ridges east of Chestnut Hill Avenue seem to be formed 
by wide separation of the rock masses along the joints, and modi- 
fication of shape upon the westerly sides by glacial action. 
At the north-western end of a long ridge of puddingstone along 
the south-west side of Washington Street, the rock must pass to 
slate, although no passage is at present exposed. The slate forms 
a small elevation crossing Breck Street between Washington 
Street and Summit Avenue, and is exposed for 100 feet along the 
west side of Breck Street. Dip is 30° to 40° N. ; strike N. 80° E.- 
S. 80° W. Going northward there comes next a little puddingstone 
and then irregular bedded sandstone, the latter showing itself at 
the surface on Breck, Allston and Warren Streets. Along Breck 
Street, south of Warren, puddingstone and sandstone alternate. 
Westward these rocks pass under the gravel hill, 180 feet high,
