a Tulip-tree, girthing 6 ft. 6 in. at 4 ft.; and another, a Beech, 
measuring 14 ft. 10 in. at 5 ft. Petasites albus, Gertn., Ranun- 
culus bulbosus, L., Cardamine amara, L., were observed as the 
party proceeded up the approach. In the shrubbery near the 
Castle was a large Arbutus Unedo, L., which, as stated by the 
gardener, bears its crop of scarlet fruit year after year. 
Some of the party desired to see the famous Heronry on the 
estate, and, under the guidance of Mr. Gillespie, a hurried visit 
was paid to it, the rest of the party returning in the direction of 
the pier, in order to see the remarkable avenue of Yews near the 
Clachan of Roseneath. 
The Heronry is in the “Green-Isle” wood, and it was estimated 
by the keeper that there were over seventy nests this season. 
The trees selected by the birds were, in every case, Scotch Firs. 
Many herons were seen, and Mr. Gillespie remarked that it was 
no uncommon thing for a hundred or more to be observed feeding 
on the beach at low tide in the evening. The young birds—few 
only of which were fledged—kept up a loud chattering as the 
parents flew backwards and forwards. 
Dovucatston Locu, 5th June, 1894.—This was an evening 
excursion, and there was little to call for notice excepting that 
the fresh-water Alga, Aphanothece stagnina (Spr.), was met with. 
TULLICHEWAN CasTLE, 16th June, 1894.—Permission to visit 
Tullichewan was courteously granted by Mr. James Campbell, who 
sent his gardener and forester to Balloch Station to meet the 
party, which numbered twenty. 
A visit was first made to Woodbank, where, in the park in front 
of the house, there are three handsome Elms—one particularly 
fine, of which a photograph was taken. A double Scarlet Thorn 
also attracted attention by its brilliant blossom. Proceeding 
towards Tullichewan, interest was taken in the fine Conifers and 
shrubs, arranged here with taste. Among the trees Picea Punsapo, 
Loudon (the Pinsapo Fir), and Abies Mertensiana, Lindley (the 
Californian Hemlock Spruce), were worthy of note, while the 
Rhododendrons and Guelder-roses, in abundant bloom, were
