The rate of two young trees girthing 10 ^-o inches 

 and llt*o inches at 5 feet, at Dalswinton, Dumfries, 

 grown under the same conditions as the larches and Scots 

 tir (which see), for eight years, was 1"27 and 1*43, some- 

 what under that of the Scots fir, and greatly below that of 

 the larches (D. Christison, Ap. 1893). 



Yi, The Larch {Larix europcva). 



This species was introduced in Scotland by the Duke of 

 Athole in 1727, although it was known in England prior 

 to 1629. Perhaps "the period is not yet long enough to 

 establish the size which the species may attain, but one of 

 the original trees at Dunkeld is now (April 189 3) 15 feet 

 1 inch in girth at 5 feet up, although it has probably been 

 growing very slowly for some years back ; and another, at 

 Monzie Castle, Perth, is no less than 16 feet 1 inch at the 

 same height. The larch apparently attains, in Scotland, a 

 greater height than the Scots fir, as a rule.
