veiled the landscape, through which objects at no great distance 
loomed indistinctly, whilst those afar off were quite blotted out from 
sight. Not a glimpse could be caught of the Grampians, and even 
the course of the ample Tay could be but faintly traced. After a 
brief rest the party made the descent of the hill and regained the 
road at the point where it is crossed by the railway. Here they were 
joined by the President and Dr. Buchanan White, who had driven 
from Perth. The latter pointed out at this place a clump of Sambucus 
Ebulus , the dwarf elder or D anew ort, and gave an interesting account 
of the plant and of its distribution in Perthshire. 
Proceeding next to the lower end of Glenfarg, the road up the 
glen was followed. It was a great relief to escape from the broiling 
sun into the cool shade of the glen. 
“A halt was made at Glenfarg Quarry, which is situated midway 
between Aberargie and the Bein Inn, to examine the structure of the 
rocks. In this quarry a fine section is exposed of the beds of volcanic 
rock (Porphyrite, &c.) which were laid down during Old Red Sand¬ 
stone times, and which were subsequently arched up in the line of 
the Sidlaw and Ochil Hills. In this particular district they had 
evidently undergone a large amount of local disturbance in addition 
to the general upheaval. This was shown by the deep synclinal 
trough, extending half-way across the quarry, into which the beds 
had been bent; by the numerous joints and small faults which have 
been developed; and by the highly ‘slickensided’ structure of the 
joint-faces. The porphyrite in this quarry is fairly compact and 
close-grained, but a little further up the glen it becomes more open, 
or ‘amygdaloidal,’ with distinct steam cavities, indicating the upper 
portion of a lava flow which had cooled at the surface. In these 
steam cavities numerous minerals have subsequently been deposited, 
such as agate, calcite, zeolites, etc. Some good specimens of these 
were secured by the party, including some crystals of quartz in which 
had been developed black needle-like spicules of apatite.” 
Before leaving this interesting spot the party were formed into 
a group and photographed by Mr. S. T. Ellison, and then the road 
was followed to the Bein Inn. It could not be expected that at 
such an early period of the year, and in a locality so often and so 
thoroughly searched as Glenfarg, any great find would reward the 
toil of the botanists. A few plants were got in flower of Geranium 
lucidum and Lychnis viscaria. The only other plant which need be 
mentioned was Geum intermedium , of which fine specimens were 
plentiful. After a welcome tea at the Bein Inn the journey back to 
Glenfarg Station was proceeded with. 
“A few yards above the Bein Inn, in a cliff by the side of the road, 
a section of tuffaceous conglomerate was examined. This represents 
the loose material, consisting of angular fragments and fine dust, 
which had been blown out from the neck of the volcano, from which 
also the streams of lava forming the cliff had flowed out.” 
The entomologists reported that during the day insects were 
scarce. Three specimens of a fine elaterid beetle, Corymbites 
cupreus , distinctly Scottish, were secured on the wing. This beetle, 
though generally distributed, is not common in our district.
