the neighboring shore, and occupying a space of several acres, were 
seen in promiscuous assemblage, a multitude of boulders both large and 
small, composed chiefly of granite, syenite, greenstone, conglomerate, 
and red sandstone, apparently the companions of this extraordinary 
specimen. ‘There is no stream of any magnitude or importance nearer 
than Elm river (three miles), which although called a river, is not more 
of two or three degrees. out eight or ten miles southward is a 
ridge of stratified greenstone, generally called trap by explorers in this 
region. This ridge rans northeast and southwest nearly, and attains 
a height of five or six hundred feet. In this greenstone are numerous 
veins containing native copper with occasional spots of silver. ‘These 
veins or lodes of copper, cut the above ridge at right angles and extend 
into a formation of conglomerate which reclines immediately upon the 
stone.—T wo fossil trees have recently been discovered by the quarry: 
men who were excavating building stones in a sandstone quarry on t 
banks of the Pequabuck river in the town of Bristol, Connecticut. This 
town is on the western border of the greater secondary basin of Con- 
necticut, and the locality where these fossil trees were found is not far 
from the junction of this deposit with the western primary ranges. 
The sandstone beds which crop out upon the banks of the Pequabuck, 
are fine grained, argillaceous and well adapted for many architectural 
purposes. No organic remains have before been observed in them, 
with the exception of a few ill characterized and obscure impressions of 
reed-like vegetation, upon the surface of a fissile stratum of argillaceous 
sandstone which is met with at a point about four feet above the 
ee 
taining the trees.
