 described. Most of these show a general parallelism with the other 

 Appalachian ranges. But the Blue Hill range of Milton and 

 Quincy, trends east and west, and other ranges of low hills, in the 

 vicinity of Boston, are approximately parallel. The general strike 

 of the rocks usually appears to be nearly parallel with the trend of

 elevation produced by a secondary force, which acted in a somewhat 

 different direction from the primary one which determined the pre- 

 vailing course of the Appalachian Mountain System.
