Parallel to each other, but at a distance respectively different, and 

 nearly vertical to the main direction of the chain ^ there are three trans- 

 verse vallies, the bottom of which, if not on a dead level with the 

 sea, comes at least very near to it. The first of these is situated in 

 the middle part of the chain, and the road leading from Douglass to 

 Peel town passes through it. Its watershed is one hundred and 

 twenty-six feet above the level of the sea, from which on the 

 northern side rises a steep slope of 1352 feet to the top of the 

 North-Greebah, and on the southern side a nearly vertical preci-
