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 there the scenery is enlivened eastwards by the adjacent area 
of cultivation. An old resident informed me that during his life the view 
of the county 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 4 miles south-west of Kirkcowan, and is a somewhat 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 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 with that of a lochan in the midst of a peat moor. Other 
uncommon members of the marginal flora were Cladium Mariscus and 
Hypericum elodes, while the more usual species, such as Carex rostrata, 
Juncus effusus, J. bufonius, Menyanthes trifoliata, Narthecium ossifragum, 
Eriophorum polystachion, Hydrocotyle vulgaris, etc., formed the bulk of 
the phanerogamic vegetation. The following Bryophytes were also 
abundant : — Sphagnum cuspidatum, var. falcatum, S. cymbifolium, S. 
subsecundum, Polytrichum commune, Aulacomnium palustre, Hypnum 
Schreberi, H. cupressiforme, var. ericetorum, Cephalozia Spliagni, etc. On 
the drier parts of the bog Calluna and Myrica have spread from the adjacent 
moor, where Cladonia uncialis occurs in extraordinary abundance. I was 
not able to discover what plants, if any, grew in the water. 
Fell Loch is larger than Wayoch, and \ mile south-east of it. The 
water is peaty, and the bottom is of peat. The chief plants are Lobelia 
Dortmanna, Castalia speciosa, Potamogeton polygonifolius, Juncus fluitans, 
Heleocharis multicaulis, Cladium Mariscus, Carex rostrata, Phragmites 
communis, Equisetum limosum, Menyanthes trifoliata, Hydrocotyle vulgaris, 
etc. 
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, as well as other commoner plants. 
Mochrum Loch is \ mile south of the last mentioned, but is much 
larger, being about 1J miles long by ^ mile broad, and the elevation 
above sea level is 248 feet. This loch is very shallow, the average depth 
* A wet moor, with much Sphagnum, etc., is frequently called a moss.
