ticity. On the adjoining hillside, however, were a number of mounds 
of a different character, regarding the origin of which there could 
not be much doubt. These were moraines, deposited towards the 
close of the great ice age, as the glacier which once filled up the Sma’ 
Glen gradually receded before the advance of a warmer climate. 
The final excursion took place on 2nd September, one of the 
hottest days of a hot summer. Going to Comrie by train, the day 
was devoted to an exploration of part of Glenartney, which we 
entered by the road which runs on the south side of the Ruchill. 
On the left side of the road, about a mile from Comrie, and close 
beside a “standing stone” (not mentioned in the map), a slab with 
a number of those “ cups,” whose origin and meaning is shrouded in 
mystery, was observed and examined. Passing on we were glad to 
see that the patch of Sambncus Ebulus near Cultibregan, which v T as 
first noticed during an excursion to Glenartney some years ago, was 
still in existence. At Milntuim we left the road and descended 
through a wood to the bed of the Water of Ruchill, which we 
ascended for some distance. It is possible that earlier in the season 
a greater variety of plants might be found than w r e met with. 
Amongst the species seen were Carex remota (in great abundance in 
some spots), C. sylvatica , Circcea alpina , and Vida sylvatica. The 
Ruchill does not seem to be prolific in alpine plants, the only 
species seen being Saxifraga aizoides and Alchemilla alpina. At a 
picturesque waterfall—Sput a Chleibh—the absence of the photo¬ 
graphic members was much regretted. A good photo of this spot 
would form a nice addition to our collection of pictures illustrating 
the geology of Perthshire. At this point the stream has cut a 
passage through (1) the conglomerate, (2) a basalt dyke, (3) the 
conglomerate again, and (4) apparently Old Red Sandstone, and, 
since the rocks are massive, it is possible that the details would come 
out well.* 
Some way above the Spout we crossed to the north side of the 
Ruchill, and presently found ourselves on the Silurian formation. 
We now took our w r ay down the glen, and, after a short stroll on the 
moor near Blairmore, descended to the road near Dalrannoch (where 
we gathered Potentilla procumbent and Circcea lutetiana), and so on 
to Comrie. 
This concludes the account of the official excursions, but, as in 
former years, it seems desirable to put on record the results of some 
other explorations made during the past summer. 
The earliest record of Carex limosa as a Perthshire plant is in 
Lightfoot’s Flora Scolica (1778), where it is stated that it was found 
by Stuart “at Tullybanchar, half-a-mile west of Comrie.” With the 
object, therefore, of trying to ascertain if the Carex still grew there, 
Mr. Barclay and I took advantage, on June 3rd, of the new railway 
to pay a visit to Comrie. From information kindly furnished by 
Major Dundas we were able to find without difficulty a marsh which
