house, and some fine, but almost birdless, cliffs between, con- 

 siderably higher than Cape Wrath. 



Drove back to Cearvig, after which, accompanied by John 

 M'Callum, I ascended to the top of Clo-More — a very fine 

 nursery of sea birds. The height of Clo-More, according to 

 survey, is 600 feet. From this point, we looked down upon 

 the comparatively diminutive stacks, which, however, are 

 singularly picturesque ones, and are crowded with sea birds. 

 On one fine broad ledge I counted 100 guillemots, and on 

 another upwards of 60. The pufBn, however, keeps up its pro- 

 ductive powers here on a vast scale, and sustains, as a gregari- 

 ous species, the character of being the most numerous of all our 

 sea-fowl. The colony extends nearly 3 miles, the area being 

 more or less densely populated in its rubble slopes and cairns, 

 crevices of the rocks and turf summits, throughout its whole 

 height, which averages 450 feet. Eazorbills and guillemots 

 are both plentiful on the stacks. I could not make out any 

 bridled guillemots, the distance being too great. Kitti wakes 

 abound at several detached and suitable places towards the 

 east. A pair of peregrines were seen in Clo-Bheag, which is 

 between Clo-More and Cearvig at the entrance to the bay, 

 and soon a single young bird in down was seen in the 

 nest. It appeared through the glasses to be about the size 

 of a puffin, which was sitting not far from it. The nest or 

 eyrie was situated in an apparently inaccessible place, viz., 

 the top of a mound of d^hris, or grass-covered rubble, which 

 rested on a sheer precipice of 150 feet. Above it the rock 

 overhangs, but there is a rent in the cliff', down which it 

 might just be possible for a man to descend with a 

 rope. It will be thus seen that peregrines are fairly 

 numerous on this coast. I have myself seen or heard of four 

 pairs between Cape Wrath and Whiten Head. 



The white-tailed eagles bred for many years on the high cliffs 

 east of Clo-More, and between Clo-More and Garbh Island, 

 but in 1879 Mr Colquhoun (author of the " Moor and the 

 Loch ") shot one of the old birds. Since then the other bird 

 has been solitary, and has frequently been seen, but has never 

 taken to itself another mate. No doubt these are very old 

 birds. M'Callum once took the eggs at this eyrie, and they
