sandstone, and picturesquely shaped. At the head of Little Loch 

 Eroom rises the magnificent Teallach (3483 feet), occupying nearly 

 the whole space between Little Loch Broom and Strath na Sheallag. 

 It is mainly composed of Torridon sandstone, but its east buttresses 

 are capped with quartzite. It is formed by a number of peaks 

 closely congregated together, connected by narrow ridges, its 

 principal summits rising to a considerable height above the cols. 

 Its eastern face is carved into two enormous corries, divided by a 

 sharp ridge, and encircled by precipices with jagged peaks. The 

 south corrie contains a dark green tarn — Toll an Lochain — which 

 for savage grandeur is only surpassed by Coruisk. The cliffs at the 

 head of the tarn are about 1800 feet above the water, and in one 

 place descend sheer into it. They are broken into buttresses and 

 spires of the wildest imaginable forms. The principal peaks, com- 

 mencing in the north, are — Glas-Mheall-Mor (3176 feet); Bidein 

 a' Ghlas Thuill (3483 feet); Sgurr Fiona, at the head of Toll an 

 Lochain (3474 feet); Sgurr Creag an Eich (3350 feet), above Loch 

 na Sheallag, connected by a long ridge with Sgurr Ruadh (2492 

 feet). A very remarkable stream, noticed by Dr. M'Culloch in his 

 book on The Hebrides aiid Western Isles, descends from the 

 Teallach into Little Loch Broom, about two miles from its head, 

 and displays along the last mile of its course almost every variety 

 of waterfall scenery. West of Teallach is the curious dome of 

 Sal Mhor (2508 feet). 



South of Strath na Sheallag there is a large group of rugged 

 summits all of marked individuality. Beinn Dhearg Bheag (2650 

 feet), Beinn Dhearg Mhor (2974 feet), have jagged summits like 

 parts of Teallach; Beinn a' Chlaidheimh (2960 feet), Sgurr Bkn 

 (3194 feet), and Mullach Coire Mhic Fhearchair (3320 feet), are 

 capped with quartzite, and are consequently extremely rough and 

 stony. On the east slope of Sgurr Ban is a very peculiar slab of 

 quartzite rock. The whole surface of the mountain is quite bare 

 and set at a very low angle ; the rock is so exceedingly slippery as 

 not to be easily walked upon with nailed boots. Out of the centre 

 of this desolation rises a curious little green cone, called Meallau 

 nan Laoigh. To the west of these summits rises Euadh Stac Mhor 

 (2940 feet), which, from some points of view, resembles a cap of
