240 THE FRESH-WATER LOCHS OF SCOTLAND 
engaged ; but a close examination of the barren shore, for the 
remains of submersed plants, suggested a scarcity of vegetation in 
the water. Although these three lochs possess a fair number of 
plants between them, yet they are not of much interest botanically, 
so far as I could find. 
Clugston Loch is a small sheet of water three miles south of 
Kirkcowan, with slightly peaty water, and surrounded by moor. The 
shores are rocky or peaty, and, beyond colonies of Carex rostrata, 
C. Goodenovii, and Equisetum limosum, there are no large associa- 
tions of semi-aquatic plants. A number of other common species 
flourish on the shores and in the water. 
Loch Wayoch is the most northerly of a group of lochs situated 
on a dreary, boggy moor, many miles in extent. The last-mentioned 
loch is indeed upon the same moor, but at its outskirts, where the 
ground is less boggy, whilst the scenery is enlivened eastwards by the 
adjacent area of cultivation. An old resident informed me that 
during his life the view of the country beyond the moor (i.e. looking 
from Anabaglish southwards) had been considerably curtailed owing 
to the gradual elevation of the intervening moss.^ Exact measurements 
of such development over a long period would not be without interest. 
This loch is four miles south-west of Kirkcowan, and is a some- 
what circular pool 200 yards across. There is no shore, the water 
being surrounded by deep bog differing only from the moor in being 
more ready to engulf the unwary. I succeeded in getting within a 
few feet of the water, and was surprised to find that it was beautifully 
clear and apparently not peaty. Another interesting fact was the 
presence of an association of Typha latifolia, a plant usually associated 
with the evil-smelling mud of lowland lakes rather than a lochan in 
the midst of a peat moor. Other uncommon members of the marginal 
flora were Cladium Mariscus and Hypericum elodes, while the bulk of 
the encircling vegetation was composed of a variety of the usual 
species. Amongst a number of Bryophytes that flourished in the 
surrounding bog, the interesting Cephalozia Sphagni was abundant. 
On the drier parts of the bog Calluna and Myrica have spread from 
the adjacent moor, where Cladonia uncialis occurs in extraordinary 
abundance. 
Fell Loch is larger than Loch Wayoch and half a mile south-east 
of it. The water is peaty and the bottom is of peat. A number of 
plants common to the district occur in it. 
Black Loch is close to the last-mentioned and similar to it, but 
the water is not so peaty, and there is less vegetation. Cladium 
Mariscus and Carex filiformis are abundant here, amongst other 
commoner plants. 
1 A wet moor with mucli Sphagnum, etc. , is frequently called a moss.
