may be named after their most conspicuous summits the Cior-Mhor, 

 Goatfell, and Ben-Varen groups. Of these by far the most con- 

 siderable is the first, which forms a long irregular, narrow, and 

 jagged ridge, extending from Ben-Ghnuis on the south to Suithi- 

 Fergus on the north-east. Cior-Mhor stands near its centre at a 

 point where 'a salient angle in the ridge closely approaches to the 

 Goatfell group on the east. Its connection to this group by a 

 cross ridge or col about 1,000 feet in height, which separates the 

 heads of Glen Rosa and Glen Sannox, and its position near the middle 

 of the range, constitute the prominent peak of Cior-Mhor, the geo- 

 graphical centre of the whole north-eastern mass of mountains. Its 

 height is about 2,500 feet ; but it is exceeded by Caistael-Abhael, 

 and perhaps another summit. The whole ridge has great persistent 

 altitude, no point descending below 1,600 feet, and there being at 

 least six summits not less than 2,000 feet. Fronting the concavity 

 of this arch-like ridge on the east, is an assemblage of closely con- 

 nected mountains dependent upon Goatfell. The most northerly 

 summit is the lofty conical peak of Ciod-na-Oich, or the Maiden's 

 Breast, guarding the south-east angle of Glen Sannox ; on the south 

 the group terminates in the bold precipice called Glen Shant rock at 

 the entrance of Glen Rosa. Both groups front the interior glens in 

 tremendous precipices, while they descend with less abruptness to 

 Glen lorsa on one side, and the sea on the other. To the west of 

 the geographical axis of the island lies the Ben-Varen range, with 

 some connected and lower heights east of it, the entire group being 

 separated from the other mountains by Glen lorsa and Glen Eais- 

 na-Vearraid, running respectively S.S.W. and N.N.W. through the 

 length of this half of the island. These glens have a common 

 watershed in Loch -an-Dea vie, a small mountain lake or tarn, which 

 when it stands at a high level, as in winter and in wet summers, 

 discharges its waters at both ends. Another small lake adjoining, 

 at a higher level, likewise discharges, when full of water, north-west 

 into the head of Glen Catacol and south-east into Glen lorsa ; but 

 it is a mistake to suppose that Loch Tanna, the largest lake in the 

 island, has this singular position ; the ground rises suddenly north of 

 it, and all the water passes off into the lorsa. These Arran lakes 

 illustrate an arrangement which occurs on a large scale in Canada and 

 Norway, where lakes extend across the entire watershed between two 

 seas. 



The bleak uplands between Ben-Ghnuis and Ben-Varen are finely 

 varied by several heights, of which the most remarkable is the 

 prominent ridge of Sal-Halmidel, an outlier of the latter range. It
