plants, composed chiefly of Carex rostrata, Heleocharis palustris, Lythrum 
Salicaria (fig. 74), Spiraea Ulmaria, and the recently mentioned species as 
well. At the south-east end of the loch there is a marsh, with the usual 
common plants (fig. 72). The most important plants about the shores of 
this loch are as follows : — Scirpus lacustris, Equisetum limosum, Glyceria 
fluitans, Heleocharis palustris, Phragmites communis, Typha latifolia (figs. 
73, 74), Carex rostrata, Lythrum Salicaria, Juncus acutiflorus, J. eflusus, 
Phalaris arundinacea, Spiraea Ulmaria, (Enanthe crocata, Deschampsia 
caespitosa, Mentha aquatica, etc. 
In the canal between the two lochs, Littorella lacustris, Alisma ranuncu- 
loides, Potamogeton Zizii, Myriophyllum alterniflorum, Callitriche 
autumnalis, and C. vernalis are the dominant species. Bryophytes are 
everywhere scarce. 
Cults Loch is £ mile east of the last mentioned. It is a small, some- 
what circular loch, with non-peaty water, surrounded by meadow-land. 
This loch has no visible effluent, and near its centre the remains of a lake 
dwelling or crannog are to be seen. At the north-west and south-east 
sides there are small bogs; at other places a narrow zone of marsh, chiefly 
occupied by Juncus eflusus, intervenes between the water and the pasture 
(fig. 75). No other features of interest were noticed here beyond a number 
of plants which need not be especially enumerated. 
Loch Magillie is about a mile south-west of White Loch. It is a small 
oval lake 43 feet above sea level, having clear, non-peaty water, and no 
visible affluent or effluent. This loch is situated in a hollow, and the 
meadow-land, which surrounds it on three sides, runs down almost to the 
water’s edge, a narrow strip of stony shore intervening. The shore is 
chiefly occupied by Juncus eflusus, with which a few other plants are 
mingled, hut there is no marsh. At the south-west side there is a planta- 
tion between the water and the adjacent road. The average depth is from 
6 to 8 feet, and the floor of the loch is almost entirely covered with vegeta- 
tion. Littorella lacustris carpets the bottom to a depth of 3 feet, and, 
creeping up the shore, mingles with the grass of the meadow. Lobelia 
Dortmanna is abundant to a depth of 5 feet, whence long peduncles elevate 
the flowers above the surface. Isoetes lacustris is abundant from 4 to 
8 feet deep. Elatine hexandra occurs in patches very plentifully from 
the margin to 6 or 7 feet deep, and also on the shore (p. 74). Nitella 
opaca is very abundant from 4 to 9 feet deep. Fontinalis antipyretica 
and Potamogeton obtusifolius are scarce. Besides the above there are a 
few of the usual plants. 
Soulseat Loch, which has a very irregular outline, is close to the above,
