and Brough. Mr. Goodchild* gives the following sequence 
at Ash Fell : — 
a. Main mass of the carboniferous limestone. (1,000 ft.) 
h. Soft red sandstones, often conglomeratic, with traces of 
coal plants, alternating with thin shales and lime- 
stones. (500 feet.) 
c. Limestone, rather impure, but not split up by sand- 
stones and shales. (500 or 600 feet.) 
d. Shales and thin impure limestones passing down- 
wards, through calcareous beds of a more decidedly 
conglomeratic character, into a series of apple-green 
conglomerates and chocolate and grey shales. 
e. Drift-like series of red conglomerates, sandstones, and 
shales of variable thickness. These are the beds 
which in various localities are seen resting uncon- 
formably upon the silurian rocks. They pass up- 
wards into d without any clear line of demarcation. 
A series, similar to a, h, c of the above, but less calcareous, 
is found near Brough, in the escarpment. 
Thus we see that there is in several locaKties a mass of 
coarse conglomerate which passes upwards through a series 
of fine conglomerates, red sandstones, shales, and limestones, 
more or less pure, into the main mass of the carboniferous 
limestone. 
7. Ide of Man. — In the Isle of Man there are two 
districts in which we find red beds resting on an irregular 
and denuded surface of silurian schists. The carboniferous 
limestone occurs in the S.E. of the island, and in various 
points showing from under it we have a thick-bedded red 
conglomerate, very similar to that in Cumberland. It is best 
seen in the small peninsula of Langness, opposite Castleto"\vn,
