72 EXCURSIONS TO BUTE AND CUMBRAE. 
The following were also noted, but not in flower :—Avenaria 
trinervia, L., Geranium lucidum, L., Alisma ranunculoides, L., and 
Zostera marina, L. The ivy, Hedera Helix, L., was in fine fruit 
on the cliffs. The following ferns were gathered :—Asplenium 
Ruta-muraria, L., A. Adiantum-nigrum, L., and Scolopendrium 
vulgare, Sm. 
The frequency and beauty of the poet’s lichen, Parmedia 
darietina, P. saxatilis, and Evernia prunastri chiefly attracted 
attention in lichens. Some puff balls were also gathered, 
but in seaweeds, partly owing to the state of the tide, nothing 
was done. 
Some of the party engaged in dredging operations in Millport Bay. 
About thirty species of birds were noted, amongst which were 
the heron, golden plover, and oyster-catcher, and most of our 
commoner local inhabitants, but our spring and summer visitors 
were still conspicuous by their absence. 
Mr. John Stewart took a few photographs, mostly of geological 
interest, including a view of the trap dyke known as the Lion 
Rock. 
Under the most favourable conditions of wind and weather, 
Mount Stuart was visited on 7th April, 1890 (Glasgow Spring 
Holiday). ; 
This excursion had been arranged by the Zoological Society of 
Glasgow, who had kindly invited our Society to participate. The 
rendezvous was Rothesay, and on arrival there the company 
immediately proceeded by the high road to Mount Stuart policies. 
On old walls by the roadside a great profusion of the dimple- 
wort, Cotyledon Umbilicus, was noted. After entering Mount 
Stuart grounds, and on the way to the mansion house, many great 
cherry and Portugal laurels attracted attention. The long avenue 
of lime trees, known as the Lime Walk, with its vista closed by 
the sea, was much admired. 
Proceeding, a heron on the wing was noticed, and inquiries 
being started, it appeared that there was a small heronry in the 
policies, which was then visited. Under the nesting place the 
bones of an adult heron and some fragments of eggs were 
discovered. . 
After passing the house, an example of the oriental plane 
arrested attention.
