DISTRIBUTION OF SCOTCH GRANITE. 



Granite in Scotland. 



The granite masses of Scotland are chiefly developed along the 

 course of the Grampian chain, about Peterhead, west of Aberdeen, 

 on both sides of the Dee extending almost to Braemar; one large 

 mass includes Ben Mac Dhui and Cairngorm, another includes Loch- 

 nagar. A smaller mass occurs in Glen Tilt, another mass around 

 Loch Luydan, east of Glencoe, and about Loch Etive, a considerable 

 mass includes Ben Cruachan. The base of Ben Nevis is of granite, 

 and there is a remarkable mass of granite at Strontian around the 

 head of Loch Sunart. Granite occurs in the Ross of Mull, and in 

 the central part of that island. Many smaller masses are found in 

 the north of Scotland, as at Strathie Point, and between Strath 

 Ullie and Strath Halladale ; and in the south of Scotland in Arran, 

 south of Loch Doon, in the upper course of the Dee, and in the well- 

 known mass of Criffel in Kirkcudbrightshire. 



Granite of Banff. The granite of Banff came into existence after 

 the formation of the old metamorphic rocks. It sends veins into 

 them in the lower Craigellachie district. Mr. Jamieson, 7 however,

 argillaceous and arenaceous beds, and the greenstone of the Portsoy
