32 DUMBARTONSHIRE EXCURSIONS. 
is already recorded as a result of the first excursion to the island 
in 1888 (see report in Vol. I.). 
Inchmurrin, the largest and most southerly of the Loch 
Lomond islands, was visited on 19th June, 1897. A number of 
fallow deer (Cervus dama, Z) occur on the island, but are not in 
a feral state, being provided with artificial shelters in several places, 
and also partially hand-fed. A number of well grown oak 
trees are found in various places, two of which were measured : 
one about the centre of the island was found to be 15 ft. 4 ins. in 
girth at 3 ft. north-west, and another at the north end was 18 ft. 
at 2 ft. east. Two or three families of redstarts were observed, 
and a nest of the lesser black-backed gull was seen, the latter 
species having been reported as breeding here for two or three 
years previously, apparently driven from Inchmoan. 
VIIL.—ARROCHAR DISTRICT. 
The earlier visits of the Society to the mountains which surround 
the head of Loch Long, with the village of Arrochar as a centre 
and starting point, have already been fully described in the 
article upon excursions to Lochlomondside in Vol. I. The 
subsequent visits to points in the Arrochar districts lying within 
the boundary of Dumbartonshire, have been three in number, 
namely, 18th July, 1896, 5th August, 1899, and 8th April, rgor. 
The first of these occasions was during the Glasgow Fair 
holidays, when a small party of members visited Arrochar and 
remained over the week-end, the principal objective being, however, 
in the neighbouring county of Argyll. The weather prevailing 
being very unsettled, little work was done within the boundaries 
of the county now being considered, and nothing of interest falls 
to be recorded. The magnificent ash-tree in front of the 
Temperance Hotel again commanded the admiration of the party. 
Particulars regarding the dimensions of this fine tree are given in 
the former account already referred to. 
On the second occasion mentioned the party ascended the hill 
of Cruach-Tairbeirt, behind Arrochar village. This low eminence, 
1364 ft. in altitude, although surrounded by high mountains, 
nevertheless commands one of the finest views in the district, 
owing to its peculiarly advantageous position, the summit being in 
line with the opening of the Loch Sloy valley (the lake itself
