Wolfshollow near Salisbury, Connecticut. (C. A. Lee, American Journal of Science and Arts, 1824, vol.

It is in mica-slate, and is sheltered by large trees.

Natural Ice House, near Meriden, Connecticut. (Benjamin Silliman, American Journal of Science and Arts, 1822, vol. IV., page 174.)—It lies between New Haven and Hartford, about 32 kilometers from the sea, at an altitude of about 60 meters. The ice is found in a narrow defile of perpendicular trap rock, at the bottom filled with broken stones. The defile is so placed that in summer the sun only shines into it for about an hour each day; it is also well protected by surrounding trees, the leaves from which form beds at the bottom among the rocks and help to protect the ice.
