lochs. Carex rostrata, Equisetum liniosum, Phragmites communis, Lobelia 

 Dortmanna, and Littorella lacustris are its most abundant plants. 



Descending- northwards from Loch Brecbowie for about a mile, one 

 comes to Loclis Bradan and Lure, which are connected together by a narrow 

 channel. Loch Bradan is nearly a mile long, with a maximum breadtli of 

 a quarter of a mile. It is very shallow, the greatest depth being 8 feet. 

 Loch Lure is about a third the length of its neighbour, with a maximum 

 depth of 7 feet. The elevati(m of these lochs is nearly 1000 feet above sea 

 level. Except for a plantation of conifers on the south of Loch Lure, about 

 tlie ruins of Craiglure Lodge, these lochs are entirely surrounded by a tree- 

 less, grassy moor. Tlieir shores are rocky or stony, and the water is 

 slightly peaty. On an island in Loch Bradan are the ruins of a small 

 castle, but there is now little more to be seen than what is presented by a 

 stone sheep-enclosure. Both lochs have an area of marsh at the west end, 

 but the vegetation is dwarfed, and, like that in the water, consists of the 

 same species as grow in the lochs previously mentioned. 



Passing over the hill by way of the little pool. Loch Duh, which contains 

 nothing of particular interest, one crosses the Girvan Water and enters the 

 desolate moor in which are situated Derclach Loch and Loch Finlas, which 

 are connected by a short and narrow channel, and together form the source 

 of the water supply for Ayr. Derclach Loch is a very narrow sheet of 

 water about half a mile long and not more than 12 feet deep. Loch Finlas 

 is also very narrow and shallow throughout the greater part of its length, 

 which is 1^ miles. It widens at each end, and is therefore dumb-bell-shaped. 

 Its surface is 830 feet above sea level, being 7 feet less than Derclach Loch. 

 These lochs have a narrow shore, which is either peaty, stony, or rocky. 

 Their water is clear, but slightly peaty. They have a scanty vegetation, 

 and present nothing of botanical interest beyond a number of plants 

 common to the preceding lochs. 



The plants more or less common to all the foregoing lochs, excluding 

 Loch Doon, are as follows : — Lobelia Dortmanna, Isoetes lacustris, Littorella 

 lacustris, Subularia aquatica, Chara fragilis, var. delicatula, Nitella opaca, 

 Sparganium natans, Scirpus fluitans. Ranunculus Flammula, var. natans, 

 Castalia speciosa and its var. minor, Juncus fluitans, Myriophyllum alterni- 

 florum, Potamogeton natans, P. polygonifolius and its var. pseudo-fluitans, 

 Carex Goodenovii, C liliformis, C. rostrata, Menyanthes trifoliata, Hydro- 

 cotyle vulgaris, Ecjuisetum limosum, Scirpus lacustris, Juncus lamprocarpus, 

 J. acutiflorus, J. eflusus, Heleocharis palustris, H. multicaulis, Phragmites 

 connnunis, Caltha palustris and its var. minor, Eriophorum polystachion. 

 Ranunculus Flammula and its var. scoticus, Cardamine pratensis, Batracho-
