several of the lochs. Most probably it has made its way by some 
one of the usual modes of dispersal from that quarter to Limehaugh. 
Somewhat further down the river, in a spot where casuals frequently 
occur, a single plant of Silene armeria was picked up. On Darry 
Island, Astragalus glycyphyllos was found to be spreading, as there 
are now several patches of it along the bank, instead of only one, as 
was the case half-a-dozen years ago. On a subsequent visit to the 
marsh where the Lysimachia grows, Mr. Meldrum called my attention 
to the presence of the bog-bean, Menyanthes trifoliata. This, I find, 
is not in the 1 List of Plants of the Left Bank of the Tay between 
Perth and Glencarse,’ published in our Transadio?is in 1892,* but I 
think that the plant was there at the time, and that it was seen by 
Dr. Buchanan White and myself, but that through inadvertence I 
had omitted to take note of it.” 
No. 5, 24th July,—to Craiglea Quarry. A melancholy interest 
attaches to this excursion, as it had to be postponed on account of 
the terrible blasting accident which occurred shortly before the date 
originally fixed. Although the quarries have been in operation for 
more than a hundred years, no accident attended with such disastrous 
results had occurred before. Owing to the change of date, Mr. 
White, the manager of the quarries, who had originally suggested the 
excursion, was unfortunately unable to be present, but his foreman, 
Mr. Duncan, kindly explained the workings in his absence. The 
leader was Mr. A. S. Reid, Glenalmond. As the day was one of 
the finest of the summer, the drive from Perth was greatly enjoyed, 
particularly in the latter part, when approaching the Grampians. A 
halt was made at Harrietfield, in order to enable the photographers 
to secure mementoes of some of the reputed “ Drumtochty ” sites. 
It is to be feared, however, that the camera is only too familiar an 
object in this now famous village. Most of the time was devoted to 
the quarries themselves, which present features of very considerable 
geological interest, and here both specimens and photographs were 
secured for the benefit of the Museum. The rock is part of the 
band of clay slate which runs across Scotland from a few miles above 
Stonehaven to Port Bannatyne in Bute, and which is worked at 
several points for roofing purposes. The lines of cleavage and of 
stratification are remarkably distinct in Craiglea, the latter, which are 
emphasized in places by bands of a yellow sulphurous deposit, form¬ 
ing magnificent synclinal and anticlinal curves. Through these 
curves the cleavage is seen to cut with unvarying constancy. At the 
top of the quarry, where part of the surface was freshly exposed, some 
very well preserved ice grooves and scratches were seen. Altogether, 
the quarry afforded the student of geology a storehouse of fact and 
illustration that would have served for many days’ study. Regarding 
the botany of the district, Mr. Barclay reports as follows: —“There 
were no plants at the quarry worthy of notice, and the immediate 
neighbourhood was not much more productive. A few of the 
commoner moorland plants grew on the hillside, and by the little 
stream which rises at no great distance. Saxifraga azoides and
