HIGHLANDS OF PERTHSHIRE. 483 
river Dochart for a mile or two; and here we thought we detected 
Alisma natans, neither in flower nor in fruit: hence this point 
must be regarded as uncertain. If it was this plant, it was the 
only interesting alpine aquatic observed in our Highland tour. 
From the bank of the river we ascended the very steep hill of 
Shroineach Lochan, but noticed scarcely anything which we had 
_ not previously observed. On the high rocks grew in luxuriant 
patches Epilobium angustifolium, which had not yet (the 11th of 
July) expanded its bright purple blossoms. A fine object it is, 
on these alpine craigs, when it is in full flower, which is about a 
month later than the period when we observed it here. 
The views from the summit of this mountaim were very exten- 
sive, embracing the greater portion of Loch Tay, its bounding 
mountain-chains, Glens Dochart and Lochay, Ben More, and 
the far more distant hills of Athol and of the West Highlands. 
The descent from the summit was not easily accomplished, nor 
without some slight injury to our muscles. The road—for there 
is a cart-road leading over the mountain to the peat-moss—is a 
zigzag, like that at Clifton, magna componere parvis. The English 
zigzag has the advantage in breadth and smoothness, but its 
Scottish rival excels in extent. The distance from the table-land 
to the summit of Clifton high rocks may be about 300 feet: to 
the summit of Shromeach Lochan the altitude is probably nearly 
ten times as much. 
The distance from the summit of this hill to the village of 
Killin is probably a mile, but as steep as the ascent to Twll-du 
in Carnarvonshire. The zigzag road is at least three times as 
long, and not remarkable for the equality of its surface. The 
zigzag road from the summit of Clifton Downs is wide and level; 
a coach-and-six may be driven on it with safety. The zigzag 
road near Killin is narrow, rutty, and rough. The hill is worth 
ascending, for the sake of the ample view obtained from its top. 
The botanist need not trouble himself with a vasculum, for it is 
not a rich botanical locality. 
On the 13th, Boreland Falls, on the Lochay, about two miles 
from Killin, were visited. Along the roadside which leads up 
the Glen several examples of Geranium pratense were observed, and 
G. sylvaticum did not occur so frequently nor so abundantly as 
it had heretofore. A very large and old stock of Rides rubrum 
was also noticed. During the whole course of our walks through
