30 BULLETIN OF THE 



well-defined limits which mark the principal train, hence its width can- 

 not be so accurately given, though it may be stated approximately us 

 800 feet. The boulders of this gi-oup are only about half as numerous 

 as are those upon an equal area of the corresponding part of the princi- 

 pal train. 



Upon the eastern slope of the West Branch of the Richmond 

 Range, in the Haskell Valley, is another group of chloritic schist boul- 

 ders having a linear extension, but in a north and south direction, and 

 again, upon the eastern slope of the East Branch, a similar distribu- 

 tion may be noted. 



Passing southeasterly to the Congregational Church on the main road 

 in Richmond, another group may be seen extending southeasterly from 

 the church to a point half a mile distant, in the bottom of the Richmond 

 Valley ; here the detrital accumulations of the meadow cause a gap of 

 an eighth of a mile, beyond which the train continues in a nearly south- 

 easterly direction to a point about half a mile south of Mr. Slosson's 

 house in the southeastern part of Richmond, beyond which it has not 

 been traced. 



In width and in abimdance of boulders that portion of this train 

 which extends from the Congregational Church to the point just men- 

 tioned resembles the corresponding portion of the principal train. 



Between the different groups which make up this train are spaces 

 destitute of chloritic schist boulders, and, unlike the principal train, this 

 one does not extend to the crest of the Canaan and Lebanon Range. 



The boulders of this train are, in general, smaller than those of the 

 principal train. They, however, resemble those of the principal train in 

 shape, in freedom from the effects of abrasion, and in exhibiting a 

 diminution in size and numbers from the northwest towards the south- 

 east. 



c. Third Train. 



Southwest of the second train lies a third parallel, but still more 

 fragmentary, train. The most westerly of the detached groups of which 

 it is niade up lies upon the eastern slope of the si)ur next south of 

 Dupey's Mount, and has nearly a circular form, with a diameter of 

 about one third of a mile. Half a mile west of Mr. Haskell's in Rich- 

 mond, E. S. E. from the first group, lies another small group on the 

 south side of the road leading to Canaan, and half a mile north of Mr. 

 Rossitcr's, on the east side of the road, lies another in the same line 

 witli the first two. Again, half a mile to the southeast, near the Meth- 

 odist Church in Richmond, another begins, and, passing just a few rods
