polystachion occur about the shores, but mostly of dwarfed growth. 
Fig. 94 affords a general view of the loch with three of its 
wooded islands. 
There are several small lochs situated in the neighbourhood of 
the larger ones recently mentioned ; the flora of these is all of the 
common type usual to the lochs of the district, and as they possess 
no features of special interest they need not be enumerated. 
Loch Killin is situated at an elevation of about 1000 feet in a 
narrow and deep glen overshadowed by mountains. Its shores 
are rocky, excepting at the south end, and the water is peaty. 
The aquatic flora is quite ordinary to such lochs. Mention must, 
however, be made of the large quantities of Glyceria fluitans 
(fig. 95) and Sparganium natans, chiefly at the south end. The 
most interesting feature about this loch is the remarkable amount 
of detrital matter brought into it by the river Killin (fig. 96). 
The bottom of the glen south of the loch forms a flat strath, 
consisting of the alluvial sand and gravel of the river Killin, and 
extending a length of about 2 miles. Kear the loch many 
acres of this strath are covered with Juncus effusus. The south 
shore of the loch consists of this alluvium, and forms a beach of 
considerable extent. Fig. 96 illustrates this beach, and the 
manner in which it becomes overgrown with plants. From the 
main body of the vegetation of the strath we see extending over 
the gravel ; patches and isolated plants of Kardus stricta, 
Deschampsia flexuosa, Festuca ovina, Molinia cserulea, Scirpus 
csespitosus, etc. ; in the rear of these ; isolated tussocks of Juncus 
effusus occur as the vanguard from the large colony farther up the 
strath (fig. 97). Such sward as exists between these tussocks is 
mostly composed of dwarf and densely matted Equisetum arvense. 
A view of the loch from the north-west, and the steep wooded 
escarpment entering it on the western shore, is shown in fig. 98. 
About six miles to the south-east of Fort- Augustus, between 
the mountains of Carn a Chuilinn and Cairn Yangie, is an 
extensive plateau some 2200 feet above sea level ; wild and 
desolate in the extreme, it is know T n locally under the sobriquet of 
“ Siberia.” Upon this plateau are a series of lochs numbering 
about twenty. As this is probably the highest series of lochs in 
the British Islands, they merit special mention. The shores of
