Xe DESCRIPTION OF THE ISLE OF MAN 
Peel the range is divided by a valley,’ and it is everywhere 
split and pierced by glens, North of the cross valley are 
some twenty summits exceeding a thousand feet. The 
mountains are usually of smooth rounded outline, the 
result of the pressure of the ice-sheet in the glacial age 
and of the deposit of its burdens of earth and clay; but 
their forms are sufficiently distinct, and viewed from the 
sea on approaching Man, they have a fine flowing contour, 
and an appearance of height greater than they really possess. 
They are generally clothed with grass, but there are tracts 
of heather and blaeberry ; at all seasons they are very devoid 
of bird life. In summer, however, Meadow Pipits nest all 
over them, a few Wheatears may be seen, and in various 
parts the Red Grouse has been introduced, or re-introduced. 
The highest point is the well-known Snaefell (2034 feet), 
which may now be ascended by electric tramway, but the 
most imposing mountain is the long and many-spurred 
North Barrule (1842), which shows from north and south a 
ridge with a rounded central summit, and from west and 
east a graceful cone. Other conspicuous eminences are the 
exceptionally peaked Pen-y-pot (1772); Greeba (1382), 
which has a rocky face overlooking the central valley; 
and the rounded Slieu Farrane (1602), over Kirk Michael. 
The glens are generally cultivated in the lower portions, 
and their fields and copses are frequented by the usual low- 
land birds ; but in their higher and upper parts steep slopes 
covered with heather and bracken descend from the open 
moorland above. Here and there along their sides are 
rocky scarps, seldom of much height or extent. The 
streams at the bottom of these glens often flow through 
fern-clad gorges, and form a succession of shaded pools. 
1 Along the bottom of this valley are strips of wet ground, and the damp 
meadows and swampy willow thickets under Greeba repeat on a smaller scale 
the conditions of the northern Curragh,
