avis, and a specimen of the small Magpie Moth 
Lomaspilis marginata. We came now to a part of the 
wood where the low copse was interspersed with 
large trees and open glades, just on the verge of a 
steep descending bank of the Almond, and which 
the President chacterised as “superb sugaring 
ground.” The river ran fully 100 feet below. A 
gentle ascending and winding path led along the 
southern bank;, and gav-e occasionally fine glimpses 
of the stream. A specimen of the beautiful moth, 
Halias prasinana (the Green Silverlines), of a light 
green, crossed with silvery lines, was picked up, 
as well as the boat-shaped cocoon, from which it had 
just emerged. Ascending a steep bank, we came to 
a rowan tree fPyrus aucupariaj in full blossom, and 
on which at least five species of bees were found 
feeding—namely, Halictus tumulorum, Andrena Trim- 
merana, Andrena nigro-cenea, Bomhus senilis (having 
the bright colouring peculiar to Perthshire specimens), 
and another not yet determined. We were fortunate 
enough also to find a speciman of the rare “Lady 
Bird,” Coocinella 16-pienctata, The Prunus Padus — 
the “ Bird cherry ”—was everywhere in full bloom, 
and its tasseled blossoms, and the white down 
bursting from the ripe catkins of the numerous 
willow trees, contrasted well with the bright green 
of the oaks and elms. From the top of a high and 
steep bank we observed an extensive bed of the Lily 
of the Yalley, Convallaria majalis, from which, after 
some trouble in descending, a few plants were got in 
flower. A large bed of Herb Paris fParis guadri- 
folia) was found growing close to the river as we 
descended to the level, and feeling the intense heat of 
the first really summer day of the season, we gladly 
sought the water-edge for rest and refreshment. The 
pool beside which we sat was immediately below the 
dam-dyke which gathers the water for one of the 
manufactories on the north side of the river. At this 
same spot another “ dyke,” of trap, intersecting the 
red sandstone, rises high on each side of the river. 
This dyke shows a columnar or basaltic structure, 
the basaltic beds lying nearly horizontal. The Bed- 
sandstone through which the dyke rises is of a soft
