characteristic, or at least as sure to attract attention. First the 

 Eing Ouzel, then the Twite, Curlew, Eedshank, Sandpiper, Common 

 Gull, Dunlin (rare). Hooded and Carrion Crow (in the scaurs), and 

 of late years a few pairs of Stock Doves at 1600 feet elevation. 

 To these we may add Blackgame, Grouse and Ptarmigan, Merlin 

 and Kestrel Hawk, and the Dipper on the streams. As plantations 

 increase, however, such birds as Whitethroats, Spotted Flycatchers, 

 and other woodland species may be expected to populate and 

 increase their 'distribution.' Formerly, before gamekeepers had 

 full sway. Hen Harriers were not unknown, but now they are 

 extinct, and even the Peregrine is getting scarcer. 



For the following notes upon the Geology and Trout of the 

 Carn District, we are indebted to our friend, Mr. Lionel Hinxman 

 of the Scottish Geological Survey. 



Notes on the Geology of the 'Ladder' Hills, j 



THE CORRYHABBIE EANGE, ETC. \ 



The continuous range of hills that runs north-east from the eastern ■ 



end of Ben Avon at Inchrory to the Cabrach, and whose water- : 



shed forms the march between the counties of Banff and Aberdeen, j 



is mainly composed of alternating belts of hard yellowish quartzite i 



and dark grey or black ferruginous slates and slaty schists. Bands : 



of limestone also occur, one in particular running up Glen Suie \ 



and down Glen Fiddich to Dufftown, and there is also a considerable \ 



development of this rock in the deep glens cut by the head-waters | 



of the Nochty on the eastern side of the range. Granite is found I 



along the lower part of the Kymah Burn extending for some dis- | 



tance up the slopes of Cairn-na-Bruar; and, associated with Diorite, j 



also forms a great part of the hills at the head of the Deveron. ! 



Serpentine occurs on Crespet Hill, at the Scores of the Blackwater, | 



and at various other points along the course of that stream. The j 



smooth rounded appearance of most of these hills is due, partly to I 



the uniform nature and weathering of the rocks of which they are i
