484: BOTANICAL TOUR IN THE 
the parts of Perthshire already visited, or which we subsequently 
visited, no Rides occurred so frequently and in so considerable 
quantities as R. Grossularia. This species, as a British plant, is 
ignored by most botanists. Judging however from what we saw, 
it is very much more common than any British species of the 
genus. Kibes rubrum and its varieties are occasionally met in 
upland woods; but R. Grossularia was nearly, but not quite, so 
common as Rubus ideus, the common Raspberry, and m Scot- 
land this plant is as plentiful as blackberries are in England. 
After visiting the Falls and emerging from the plantation in 
which they are, we rejoined the road, and walked along it as far 
as the open pastures, a mile or so beyond the Falls. Here we di- 
verged to the right, up the sloping side of Craig Chaillach, which 
bounds one side of Glen Lochay, as Shroineach Lochan bounds 
the other; and we kept ascending till we were probably about a 
thousand feet above the bed of the river. In marshy places at 
this altitude plenty of Tofieldia palustris was growimg,—a new 
acquisition, which gave us much pleasure. 
Our nearest way home led us through a very dense and steep 
pine-wood, in which we indulged ourselves with the vain hope of 
collecting Linnea borealis, which does grow in fir-woods, or 
rather in a fir wood, at Finlarig. A soaking rain however soon 
compelled us to abandon all our expectations, and we reached 
home in a non-enviable plight. Woe betide the imprudent 
wight who ventures into the Highlands without a good supply of 
warm clothing, considerably more than he can comfortably wear 
at one time! The trouble, and eke the expense, of conveying an 
important part of the contents of an ordinary wardrobe, are no 
slight impediments to travelling. Anciently, in military phrase, 
these and other necessaries were called, and properly called, im- 
pediments (impedimenta), because they hindered or impeded the 
movements of the army. But the comfort of dry and warm 
clothing, a change of raiment from the feet up to the head, from 
the subecula, the innermost tegument, to the tunica, the outer- 
most, is cheaply purchased at the cost of a few shillings. Some 
pedestrians are seen ¢here with their well-assorted packs, which 
are conveniently and comfortably disposed between their shoul- 
ders ; and these trudge along as independently as if their baggage 
was no impediment to them, but a part of themselves. Pedes- 
trians however who have seen sixty summers can rarely spare so
