DUMBARTONSHIRE EXCURSIONS. 29 
finely developed, the beautiful candelabra-like form of the 
branching, characteristic of the species, being well shewn. The 
woods of Rosneath are a favourite observation ground with 
ornithologists, the chiff-chaff being one of the special birds making 
an early appearance here in spring. 
Garelochhead was visited by the Society on 1st June, 1895, 
when the party travelled by the line of the West Highland 
Railway. Beyond Helensburgh the railway crosses the line of 
the great Highland fault, and the change from the sandstone to 
the schistose rocks of the Highlands is well seen in the cuttings. 
Nothing of special note is recorded as having been observed on 
this excursion, but, as the weather was fine, a visit to the hills 
above Whistlefield rewarded the members of the party with a 
magnificent view of the Argyllshire mountains and the entrance to 
Loch Goil. 
On toth August, 1901, a small party of members again visited 
Garelochhead, but on this occasion the objective point was the 
“hut-circles” on the Auchengaich Burn, at the head of Glen 
Fruin. The evidences of glacial action are very well seen through- 
out this district, and many stones shewing glacial markings were 
observed on the way. The hut-circles, which formed the turning 
point in the afternoon’s ramble, are about a thousand feet above 
sea-level, and are chiefly situated on the left bank of the 
Auchengaich Burn. There are more than fifty mounds altogether, 
but only a few have been opened, for it must be borne in mind 
that, when discovered, every roof had fallen in, and every mound 
was covered with turf and heather. These ruins evidently mark 
the site of an old village, but it is a very debatable question as to 
whether they are to be regarded as dating back to prehistoric 
times, or are of comparatively recent origin. 
VII.—LUSS DISTRICT. 
Excursions to Lochlomondside have always been popular with 
members of the Society, and during the frequent visits to this 
charming lake, the first objective has in most cases been the 
picturesque village of Luss. In Volume I. an account was given 
of the Society’s excursions to Loch Lomond, bringing the records 
up to the date of publication (1893). In the present account the 
subsequent visits to the south-western side of the lake, and to the
