of the peat can be seen from near Forteviot, in the Harn Valley, to as far east 
as Stannergate near Dundee. The character of the peat and the plant remains 
contained in it has been described, amongst other observers, by JAMIESON (11) and 
by G&IKIE (12). 
I was enabled to examine the peat at several places between Forteviot and Forgan- 
denny through the assistance of Prof. Grrkin, who kindly supplied me with maps showing 
the position of some of the best exposures. The peat in these places is about 3 feet 
in thickness and forms a brown, dry, hard layer resting upon the valley gravels, silts, 
and clays, and overlaid by the Carse clays. The peaty material is crowded with wood 
of all sizes, flattened and very brittle, and overlaid by a seam of sand and silt 
crowded with leaves often in the most perfect state of preservation. In the peat 
which | examined, remains of the following plants occurred: Quercus; Corylus 
Avellana, L.—wood and numerous nuts; Betula alba, L.; Alnus glutinosa, 
Gaertn.; Salix, sp.; Menyanthes trifoliata, L.—several seeds; Carex, sp.; 
Phragmites communis, Trin. ;—a list which adds only one fresh plant to those 
already described by the authors mentioned. The overlying sandy clay contains 
numerous leaves of Salix, sp., and fragments of oak, birch, and hazel 
leaves. 
The plants contained in the peat evidently grew where they are now found, as 
numerous rootlets penetrate the underlying deposits. The upper leaf-bed, on the other 
hand, is clearly drifted material, as the individual leaves are separated by thin layers 
of fine sand or silt. The peat, occurring as it does immediately below the Carse clays, 
should be contemporaneous with the oldest peat in the Galloway and Tweedsmuir 
districts. 
THE 25-FEET RAISED Bracu Mosses oF WIGTONSHIRE AND DUMFRIESSHIRE. 
(One inch Ordnance Survey—sheets 4 and 6.) 
Moss of Cree.—This extensive moss lies on the west side of the River Cree, between 
Newton Stewart and Wigtown. Less than a mile to the southward the smaller mosses 
of Barrow and Carsegowan are met with, both being similar in character and situation 
to the Moss of Cree. On the westward and landward side the moss is bounded by a 
series of low hills about 100 feet in elevation, from the bases of which the beach slopes 
to the 8.E., the height of the beach at the eastern boundary being about 12-15 feet 
above Ordnance datum. Viewed from the margin, the moss presents a fairly smooth 
surface with a gradual rise to the centre, which lies about 15 feet higher than the 
margins. 
The present vegetation over most of the moss consists of Hrica Tetralix, L. ; Calluna 
vulgaris, L.—not abundant; Myrica Gale, L.—abundant near the eastward margin; 
Salix, sp.; Carex, sp.; Narthecium ossifragrum, Huds. ; Vaceiniwm oxycoccos, L.. ; 
Sphagnum ; Drosera rotundifolia, L.; D. intermedia, Hayne. The ground on each
