CHAPTER VI. 



INCREASE AND EXTENSION OF KANGE. 



In the following sketch of the increase and extension of range 

 of the Capercaillie in Scotland nnder each county, I have given 

 the distances in direct lines from Taymouth of each locality 

 or group of localities mentioned. The actual lines of advance, 

 however, must not always be understood to have followed 

 these direct radii, because, as shall be further explamed, the 

 natural courses of the luaves of distribution — if I may so term 

 their acts of progress — follow, for the most part, the trend of 

 the valleys up or down stream, or the wooded slopes of the 

 hills, seldom reaching across hare hills of any altitude. The 

 accompanying Map will, it is believed, greatly assist in indi- 

 cating the lines of advance, and should be consulted whilst 

 reading the text. Owing to the small scale of the map the 

 names of many localities are necessarily omitted, but most of 

 these places will be found upon Black's maps of Scotland, 

 and, I believe, almost all upon the Ordnance Survey sheets, 

 so far as published. 



Explanation of the Map. — The map is on the scale of 

 one inch to ten miles. 



The map shows that portion of Scotland which may be 

 said to contain the area at present occupied by the Caper- 

 caillie, excepting the Island of Arran — which may be con- 

 sidered as the seat of a separate introduction — and certain
