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 

 together like sepulchral tumuli. These mounds, composed of un- 

 stratified gravel and boulders. Dr. Buckland says cannot be referred 

 to the action of water, as they are placed precisely where a current 

 descending from the adjacent high lands would have acted with the 

 greatest velocity ; and they exactly resemble some of the moraines 

 in the valley of the Rhone, between Martigny and Lock. The vil- 

 lage of Amulrie is considered by the author to stand on a group of 

 low moraines ; and the road for two or three miles from it, towards 

 Glen Almond, to traverse small moraines or surfaces of mica slate, 

 rounded by glaciers. A few conical moraines appear also on the 

 high lands between Glen Almond and Crieff. 



Proofs of Glaciers in and near Strath Earn. — This part of the val- 

 ley of the Earn is flanked irregularly with ridges and terraces of 

 gravel, the detritus of moraines ; and on its north side, in the woods 

 adjacent to Lawers House, near Comrie, hard slaty rocks of the Devo- 

 nian or old red sandstone system have been rounded and striated. At 

 the west end of Comrie, near the bridge, blue slate rocks have been 

 also rounded and guttured. 



Evidence of Glaciers near Comrie. — In this district Dr. Buckland 

 tested the value of the glacial theory by marking in anticipation on 

 a map the localities where there ought to be evidences of glaciers 

 having existed, if the theory were founded on correct principles. 

 The results coincided with the anticipations. On a hill above the 

 gorge, called the Devil's Caldron, near Fentallich, are rounded 

 surfaces of greenstone, partially covered by moraines ; and at Kena- 

 gart, also immediately above the Devil's Caldron, is a small cluster 

 of moraines, easily separable into lateral and terminal. Two miles 

 up the valley a medial moraine forms a ridge on the level ground, in 

 front of the confluence of Glen Lednoch and Glen Garron. The farm- 

 house of Invergeldy is stated to stand on the detritus of a moraine, 

 and the glen descending to it from Ben-na-cho-ny to be partially 

 obstructed with moraines. The surface of the granite at Invergeldy, 

 which supplied the stone for Lord Melville's monument at CriefF, is 

 rounded and mammillated, but too much weathered to present a 

 polish or striae. On a hill of trap, however, half a mile south of the 

 farm of Lurg, there is a distinct polish, striated in the direction 

 which a glacier descending the subjacent valley would assume. In
