To Dr. S. Reid, formerly of Richmond, seems to belong the credit of 
first discovering, and bringing to the notice of geologists, the existence 
of trains of boulders in that region. One very distinct train, passing 
half a mile to the north of the Congregational meeting-house in Rich- 
mond, and composed of entirely different material from that of the bed- 
rock beneath, he traced to its source, three miles to the northwest, upon 
the crest of a ridge in Canaan, N. Y. He also traced it in the opposite 
direction eight or nine miles, across the Richmond Valley, the Lenox 
Range, and the Lenox Valley into the town of Lee, and he believed that 
its entire length was not less thon twenty miles. Dr. Reid also de- 
half a mile south 
scribed another train as starting from the same ridg 
of the first, and running parallel to it for a distance of eight miles. He 
seems, however, to have attempted no explanation of the phenomena 
which he described. 
Dr. Edward Hitchcock, in the American Journal of Science and Art, 
gave a restatement of Dr. Reid's observations, with some considerable 
additions thereto, and a sketch map exhibiting an outline of the topog-
