Gowrie, and the transverse barriers forming a succession of small 
lakes in the valley of the Lunanburn, to the west of that town, he 
considers to be moraines; likewise the lofty mounds comprising 
the ornamental grounds adjacent to Dunkeld Castle; the detritus 
covering the left flank of the valley of the Tay, along a great part 
of the road from Dunkeld to Logierait; that on the left flank of the 
Tumel valley from Logierait to Killicrankie; and on the left flank 
of the Garrie, from Killicrankie to Blair Athol. 
The vast congeries of gravel and boulders on the shoulder of the 
mountain, exactly opposite the gorge of the Tumel, Dr. Buckland 
is of opinion was lodged there by glaciers which descended the late- 
ral valley of the Tumel from the north side of Schiehallion and the 
adjacent mountains, and were forced across the valley of the Garry, 
in the same manner as modern glaciers of the Alps (that of the Val 
de Bagne, for example,) descend from the transverse, and extend 
across the longitudinal valleys. Dr. Buckland mentions the mam- 
millated, polished and striated slate rocks, about one mile above the 
falls of the Tumel, on the left portal of the gorge of the valley, as 
the effects of a glacier which descended the gorge: he notices also 
the rounded outline and polish on veins of quartz, which project 
eight or ten inches above the weathered surfaces of masses of mica 
slate near the same locality. Similar mammillated masses of mica 
slate retaining strie and flutings are visible at Bohaly, one anda 
half miles east of Tumel Bridge. : 
Evidences of Glaciers on Schiehallion.—The north and north-east 
shoulders of the mountain present rounded, polished, and striated 
surfaces, many of which have been recently exposed by the construc- 
tion of new roads. On the left flank of the valley called the Braes 
of Foss, and near the thirteenth milestone, a newly-exposed porphy- 
ry dyke, forty feet wide, exhibited a polished surface and striated, 
parallel to the line of descent which.a glacier from Schiehallion would 
take ; and on the right flank, one hundred yards north of the eleventh 
milestone, another and smaller dyke of porphyry presented similar 
phenomena. In the intermediate space the recently uncovered slate 
rocks and quartzite are rounded, polished, grooved, and striated, 
parallel to the direction which a glacier would assume where each 
surface is situated. 
Moraines at Taymouth.—Two lofty ridges of gravel, which cross 
the park at right angles to the sides of the valley between the vil- 
lage of Kenmore and Taymouth Castle, the hill, on which stands an 
ornamental dairy-house, and the gravel, on which are situated the 
woods overhanging the left bank of the lower end of Loch Tay, 
Dr. Buckland considers to be moraines, or the detritus of moraines ; 
also the deeply-scored and fluted boulders of hornblende rock, with 
other debris near Fortingal, at the junction of Glen Moulin with 
Glen Lyon. 
Moraines in Glen Cofield.—A remarkable group of moraines occurs 
on the high lands which divide the valleys of the Tay and the Bran; 
and between the sixteenth and fourteenth milestones thirty or forty 
round-topped moraines, from thirty to sixty feet high, are crowded
