Parallel to each other, but at a distance respectively different, and nearly vertical to the main direction of the chain, there are three transverse 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 precipice of 609 feet to the top of the North Slieau-Aalyn above the hamlet of Mullin-y-Chlea, which stands 93 feet only above the sea.
The second transverse valley is about ten miles in a direct line to the south of the first, between Purl-Keill-Moirrey and Port Erin. Its watershed is 81 feet above the level of the sea, and is a low
