(a) The Millom-Park Channels.— On Millom Park there is 

 a series of channels of a somewhat peculiar character, the best 

 examples forming a group of shallow trenches which unite with one 

 another, or bifurcate, in a rather inconsequeutial manner (fig. 14, 

 below). They either cut across the watershed (over 500 feet), or 

 cut obliquely*^ into the hillside, until they meet another channel

which started at a higher leyel. Their average direction is north- 

 north-easterly, and most of them existed for only a short time. 

 Some, however, have the characteristic trough-like aspect of 

 drainage-channels, and their floors descend in steps. Channels 

 also occur, but to a less marked extent, in the volcanic tract 

 north of Knott Hill. Although their directions sometimes corre- 

 spond with rock-structures, this is not usually the case, and they 

 do not occur elsewhere in similar rocks.
