DESCRIPTION OF THE ISLE OF MAN xxi 
These beautiful scenes are ornithologically disappointing. 
The Dipper, for which they seem to supply ideal haunts, 
is absent or rare, Sandpipers do not appear to nest, Grey 
Wagtails are few. The longest of the Manx ravines is 
Sulby Glen, penetrating into the inmost recesses of the isle, 
where wet heaths slope from the highest mountains, and 
are drained by the branches of its river, wild upland 
streams rich in ferns, and abounding like the parent water 
in rushing falls and clear deep pools. 
The finest of these branch glens is the Cluggid (throat), 
a precipitous opening which joins the main glen about a 
mile from its mouth in the plain. The swampy heads of 
the brooks afford breeding ground to a few Curlews: Jack- 
daws and Kestrels nest in some of the craggy brows, and 
Grey Crows in the scanty trees. The head of the Rhenass 
Glen is not far from that of Sulby, but its stream, joining at 
St. John’s that from Foxdale, flows west through the central 
valley into the sea at Peel. There is a long belt of planta- 
tion (‘Glen Helen’ pleasure grounds) along the course of 
Rhenass river ; after the junction, the Foxdale water, polluted 
by mine refuse, imparts its character to the joint stream, 
which between St. John’s and Peel passes through waste 
and swampy ground, where the nest of the Water-rail has 
been found. 
The two glens of Baldwin, whose streams form the Glass 
river, are of a more open and cultivated character; at the 
top of West Baldwin, now much altered by the new water 
works for Douglas, is one of the oldest and finest fir woods 
in Mau; at Injebreck, a lovely mountain nook. 
Groudle, a glen with several branches and pastoral sur- 
roundings,is now in its lower part occupied by pleasure 
grounds. 
Laxey Glen, which runs from Snaefell to the eastern sea, 
is in its upper part a wild treeless valley, its stream much
