HARDY CONIFEROUS TREES 19 



nearly 6 inches long. The timber produced in 

 this country is, judging from many specimens 

 that I have had the opportunity of examining, 

 of excellent quality, being hard, close-grained, 

 and lasting. The tree succeeds well in every part 

 of the country, and has an advantage over the 

 common Silver Fir that, owing to starting into 

 growth later in spring, it is less apt to be injured 

 by unseasonable frosts. Few trees, too, are less 

 particular as to soil, it succeeding well in reclaimed 

 peat-bog, stiff loam, decomposed vegetable matter, 

 and that of a chalky or limestone formation. In 

 warm, sandy, or gravelly soils, it is apt to suffer 

 from the attacks of a species of aphis. As a forest 

 tree, it is certainly well worthy of attention. A 

 monograph on Nordmann's Silver Fir, by the 

 present writer, will be found in the Transactions 

 of the Royal Scottish Arboricultural Society, vol. ix., 

 1879.

 1861. — As yet, this species is by no means common 

 in the British Isles, but from its undoubted hardi- 

 hood and pleasing green foliage is sure to receive 

 attention. It is of neat, rather pyramidal habit, 

 with sub-erect branches, short, crowded leaves, 

 each about i inch long, and rich deep green 

 above, often with a silvery patch near the apex 

 and two faintly marked silvery lines beneath. 

 Being of free and bold growth, succeeding well 

 even in poor gravelly soils, where many of its 

 fellows refuse to grow, and perfectly hardy, this 

 tree is to be recommended for general use through-
