'Grampians we realised that the Fair City is within more accessible 
distance from the Highlands than we are sometimes apt to suppose. 
Halting at Buchanty, both banks of the river Almond were 
examined, both below and above the bridge. Striking downwards 
first, a point was reached where the conglomerate was exchanged 
for a coarse sandstone, or grit, showing that the fault had been 
passed which divides the one from the other. The exact line of the 
fault could not be seen owing to the vegetation and debris, but its 
position could be localised within narrow limits from the configu¬ 
ration of the glen. Further down, the stratification of the sandstone 
was well seen in the bed of the stream, with a dip towards the south¬ 
east. Amongst the moss in this part of the glen a beautiful yellow 
Clavaria, or club fungus, was seen. A considerable part of the 
shady bank was covered with trailing periwinkle, which the botanists 
declared to be an escape from cultivation, but which for all practical 
purposes is now a wild plant. While we rested in the wood for 
luncheon a specimen of the beautifully-marked stag’s-horn moth 
alighted on the very sleeve of the entomologist of the party, and was 
spared the collecting box for its confiding temerity. 
Retracing our steps up stream we now made for a point a few 
yards above the bridge, where a remarkable series of “ pot holes ” 
has been worn out in the hard conglomerate rocks. These vary 
from two or three inches to as many feet in diameter, their depth 
being as great, and in some cases greater. They offered a most 
tempting field of usefulness to the photographic members, and soon 
two or three of the finest were immortalised on the gelatine film. 
At the bottoms of most of the holes could be seen the rounded 
pebbles and boulders which told of the origin of these curious 
hollows. Thus, to the seeing eye, they were stones which contained 
veritable sermons, telling of the power of the river to carve its way 
through the hardest rock. While one of the largest holes was being 
photographed the Secretary of the Photographic Section magna¬ 
nimously stepped into the breach—or rather into the hole—to act 
as an index to its depth. A little further up is a small waterfall, 
which, in addition to its picturesque aspect, is of interest as illus¬ 
trating the way in which falls cut their way backwards through hard 
rocks. It was also curious to note the way in which many old pot 
holes had in this way been cut through, leaving semi-circular cavities 
in the edges of the rocks overlooking the stream. 
Leaving the Almond the party now went along the Crieff Road 
to the Roman Camp, opposite the entrance to the Sma’ Glen. On 
the way, a small loch, or rather marsh, was passed, which seemed to 
promise a good reward to the botanist if there had been time to 
examine it thoroughly. Within a small space it presented a wonder¬ 
ful variety of plant life, both flowering and cryptogamic, and might 
be worth examining earlier in the season. Amongst the plants 
observed were Utricularia minor and Spargcinium minimum. 
The last point visited was the Roman Camp, where some of the 
members were foolhardy enough to throw doubt on the Roman 
origin of the mound, though certainly its situation—guarding the 
mouth of one of the Highland passes—seemed to favour its authen-
