Kippen j the red sandstone stretches along the north front of 
the Campsie Hillsj commonly called Gargunnock Hills. 
At Boquhan, it is traversed by a torrent of that name, at a 
natural ravine, cutting it obliquely to a considerable depth. 
(Similar sections at Leckie and Gargunnock.) This red 
sandstone, like that on the north side of the valley, is cc- 
vered by red till or tiily earth, with dip and direction also 
conformable. It presents a precipitous front to N, and the 
rivulet exhibits the succession of strata betwixt it and the 
perpendicular front of the Campsie Hills, over which it 
is precipitated at Balloch Leam. The rocks of the inter- 
vening hollow are conformable to the sandstone, of varied 
characters, and alternating until they reach the foot of the 
mural precipice of greenstone, which is rudely columnar. 
They are traversed by veins of greenstone connected with 
this stratum of greenstone. 
Sp. is from these strata. I was therefore led to the 
conclusion, that this red sandstone is a continuation of that 
on the north side of the valley, — that it passes under the 
Campsie range, at a small dip, — that the superincumbent 
strata accompany it_, — and that, in place of the Campsie 
Hills reposing on coal (as supposed by Colonel Imeie), 
that substance will only be found recumbent on their south- 
ern and eastern extremities. The diagram, Fig. 7. will 
assist the description.

* The view from the north side of these hills is singularly beautiful. 
Rising perpendicularly, the valley appears as beneath the feet; beyond 
which its wide margin (braes) appear expanded and converging-, studded 
with the seats of landholders, and strewn with farm-steads, as far as the eye 
can distinguish ; the cultivated uplands extending northwards till they meet
