HIGHLANDS OF PERTHSHIRE. 29 



zigzag, like that at Clifton, magna componereparvis. 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 Shroineach 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 Caernarvonshire. 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 Ribes rubrum 

 was also noticed. During the whole course of our walks through 

 the parts of Perthshire already visited, or which we subsequently 

 visited, no Ribes 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. Ribes rubrum and its varieties are occasionally met in 

 upland woods ; but R. Grossularia was nearly, but not quite, so 

 common as Rubus idaus, the common Raspberry, and in 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 growing, a new 

 acquisition, which gave us much pleasure.
