palustre, Hypnum falcatum, H. scorpioides, H. fluitans, H. cuspidatum, H. 
cupressiforme, Rhacomitrium aciculare, Scapania sub-alpina, various species

Lochinvar is 3 miles N.E. of Dairy. It is about J mile long by J mile 
wide, and is situated at an elevation of 736 feet above sea level, in a 
depression of a hilly, grass and heather moor. The scenery around is bare, 
desolate, and, with the exception of a few conifers about the gamekeeper’s 
house, treeless. The water, which is the source of the public supply for 
Dairy, is slightly peaty but very clear, and its maximum depth is 10 feet. 
Nearly everywhere the moorland vegetation approaches to the water’s 
edge, so that there is practically no shore, unless it be a narrow zone of 
stones or rocks (fig. 41). The bottom is rocky, save some patches of sand, 
and, with the exception of a few species which are abundant in isolated 
places, the flora is extremely poor. There are no associations of marsh 
plants about the shores ; such of these plants as do occur are either as 
scattered specimens, or in a few very small groups, — Carex rostrata, Juncus 
lamprocarpus, J. effusus, Heleocharis palustris, and Ranunculus Flammula 
being the chief species. On an island, there is a quantity of Phalaris 
arundinacea overgrowing the fallen remains of a small castle. The 
submersed plants are more interesting. Here and there Lobelia Dortmanna 
or Littorella lacustris scantily carpets the bottom, particularly at the east 
end, where there is a little sand. Utricularia vulgaris, Myriophyllum alterni- 
florum, and Fontinalis antipyretica are abundant, whilst Juncus fluitans is 
not abundant. Strange to say the following Potamogetons were all 
plentiful : — P. pusillus, P. perfoliatus, P. Zizii, and a very long-leaved form 
of P. lucens. No other plants worth noting were found here. 
Loch Dungeon is 7 miles N.W. of Dairy, at an elevation of over 
1000 feet above sea level, and near the cliff at the west side it attains a 
depth of 94 feet. Beautifully situated at the base of rocky and precipitous 
mountains, it forms a magnificent, although treeless, piece of highland 
scenery, wild in the extreme, particularly on the south and west, where the 
mountains rise almost perpendicularly from the water’s edge (figs. 42 and 
44). This loch is irregularly shaped, being almost cut in twain at one part 
by a rocky promontory from the south shore, and by gravel from a 
moraine, washed into the loch by the Hawse Burn, forming a peninsula or 
alluvial cone from the north-west shore (fig. 43). The loch is about 
f mile long by \ mile broad. Its water is extremely brilliant and 
clear, although of a steely-gray colour, and its shores are mostly rocky or 
stony. Excepting associations of Equisetum limosum and Phragmites
