MORAINES AND BOWLDER TRAINS. 549 



of di-umlins carried down the western border of the valley mark the line 

 along which the ice was deflected southwardly into its new direction. 

 South of the Holyoke range and east of the Mount Tom range the drum- 

 lins are broader, flatter, and fewer in number than farther north. 



On the hills east and west of the valley drunilins are rare of wantnig. 

 I have noted only one train — this of hills of the largest size — which enters 

 the northwest corner of Blaudford from Becket, with direction S. 35^ E. 

 A very fine one is situated a little southwest of the center of Granville. 



MORAINES AND BOWLDER TRAINS. 



The great ridge of bowlders of tonalite which passes the Catholic church 

 in Thorndike and extends southwardly, going to the west of the group of 

 high hills southwest of this village and appearing in exceptional force near 

 E. Brown's house, just west of Pahner village, and crossing the river to mount 

 the high hill just south (Bald Peak, in Monson), is a portion of a true ter- 

 minal moraine of a lobe of the ice which shut up the gorge through which 

 the Quabaug River passes northwestward from Palmer village, and fur- 

 nished the barrier for the Pahner Lake (see PI. XXXV and Chapter XVII). 

 In the latter part of its course its bowlders are exclusively of Monson gneiss 

 and of very large size, one 26 by 16 by 7 feet. 



From the large dike of granite in the center of Middlefield a well- 

 marked bowlder train is carried across Chester, passing through the center 

 of the town and traceable for a distance of 5 miles. 



Just west of the road running north from the ^dllage of Leverett a 

 prominent hill of granite is continued for a long distance southward b}' 

 a mass of bowlders so densely packed that it seems like the continuation 

 of the hill itself, and in the northern part of Worthington is a similar 

 crag-and-tail arrangement of colossal bowlders of mica-schist earned 

 southeast from a prominent hill, so closely packed that one can junij) 

 from one to another for a long distance. 



Stretching southeast from the great band i>f tine-grained granite west 

 of Burnell's pond in Chestei*field is an immense accumulation of large, 

 often immense, bowlders. It continues to the southeast corner of Chester- 

 field and on into Westhampton. 



A marked bowlder train starts from the dike of peculiar porphyritic 

 granite northwest of Leydeu and extends past the center of the town and 

 on a little east of south into Greenfield.
