316 Rogers's Account of two Remarkable 
a length of three quarters of a mile, more than fifty boulders 
of the capacity of from one to two thousand cubic feet, the 
belt in this part being only two hundred and fifty feet wide. 
Entering the Richmond valley, it presently deflects as much 
as 20° to the south, altering its course from S. 50° E. to 8. 
30° E. The belt is now hardly two hundred feet in breadth. 
From this last elbow, which is near the Richmond meeting- 
house, the train, having a breadth of from two hundred and 
fifty to three hundred feet, extends, in a line approximately 
straight, across the Richmond valley, a distance of about four 
miles. It then ascends the mountain west of Lenox, which it 
passes at an elevation about as great as where it traverses the 
knob of the Richmond ridge. On the eastern declivity of the 
Lenox mountain, the larger boulders measure from eight hun- 
dred to one thousand cubic feet. Gaining the Lenox and Stock- 
bridge valley, which is about one hundred feet lower than the 
Richmond valley to the west, the blocks become less nu- 
merous, and there are portions of the belt where they are 
almost absent, while, in intermediate sections, they occur 
thickly crowded. The train ranges on, crossing the southern 
corner of Lenox, and the whole of Lee, in which it passes the 
Housatonic river. It afterwards enters Tyringham, where it 
climbs the broad and rather lofty belt of hills called the Bear- 
town Mountains. Beyond the Lenox ridge, its average direc- 
tion is S. 35° E. Dr. Reid, from whom these measurements 
are principally derived, has followed it a distance of more than 
twenty miles, and thinks that he did not reach its termination. 
The other parallel train he has traced, from its adjacent 
source in the Canaan mountain, through a length of about ten 
miles, but is not sure that he reached the end. The blocks 
in this train are rather more sparsely and less uniformly scat- 
tered. Between these two trains, very few detached blocks 
are found. [See Plate XXV.] 
The two conspicuous trains, here described, are not the 
only ones in the district, though the rest have not as yet bee? 
traced in detail. Dr. Reid, in his communication to the Asse
