24 BULLETIN OF THE 



a GLACIAL MARKINGS UPON THE BED-ROCKS. 



The greater part of the exposures of bed-rock on the upper parts of 

 the three ranges exhibits the smooth surfaces with parallel gi'ooves 

 upon them, and the dome-shaped areas similarly marked, which are so 

 characteristic of glacial action. The Canaan and Lebanon Range is 

 thickly wooded, and has but few of these exposures, namely, — at 

 Douglas Knob, Fry's Hill, and notably upon a summit situated half 

 a mile S. S. W. from Fry's Hill. Upon Perry's Peak and along the 

 crests of the two southerly branches of the Richmond Range, are many 

 considerable areas showing the markings in question. The Lenox 

 Range, for a distance of five and a half miles along its crest, has a con- 

 tinuous succession of dome-shaped areas, many of them worn so smooth 

 as to be slippery, and generally distinctly furrowed. 



The following table gives the direction of the strise in various local- 

 ities, the same facts being indicated on the map by short, parallel 

 dotted lines.

The localities numbered (1), (11) arc worthy of special notice, as 

 showing that such markings arc not confined to the upper parts of the 

 ranges. 



An examination of the map will show that no localities of strirc are 

 given upon cither the chluritic schist and sandstone, or u])on the lime- 

 stone areas. Though the exposures of chloritic schist and sandstone
