Exotic Conifers in Britain. 



Oregon and the glaucous from Colorado — the green appears to 

 be by far the more important for British conditions. It grows 

 much faster, and yet yields better timber than the other, while 

 although a little more delicate, it is sufficiently hardy for all 

 practical purposes : —

In the case of the Douglas fir I am able to give some figures 

 from a wood (Taymount) of eight acres planted with four-year- 

 old plants in the spring of i860 on the estate of the Earl of 

 Mansfield, about seven miles from Perth, in central Scotland. 



Professor Schlich puts the quality of the locality in the first 

 class, but in doing so I think he estimates somewhat too highly. 

 My reasons for thinking so are two-fold : (1) the impression 

 gathered from an inspection of the soil is that there are many 

 more suitable situations, and (2) the height-growth recorded in 

 the table above is in many cases better than that at Taymount. 

 The planting was done in squares, the Douglas firs being 

 placed 12 feet apart, and the interspaces filled with Larch, so 

 that the trees stood 6 feet apart. An acre thus contained, theo- 

 retically, 1,210 plants, of which 908 were Larch and 302 

 Douglas firs. By the year 1880 the Larches had all been 

 removed, and in 1887 the Douglas firs were thinned, so that 

 only 202 remained per acre. The Douglas firs (600-700) 

 removed from the eight acres realised by auction sale £34. 

 There can be no doubt that too many trees were removed at this 

 time. What with too wide planting to begin with, and too 

 much thinning in 1887, the trees remaining in the latter year
