species it will be one of the most valuable timbers (Trans. Roy. Scot. 

 Arb. Soc. xii. pt. 2), 



The timber of A. Nordmanniana and A. Pinsa^^o I consider the 

 best of the Silver Firs, not excepting even the prototype A. pectinata 

 (Nelson, Pinac). 



A. Nordmanniana has at an age of about thirty years measured 

 40 feet in height and 3 feet in girth. It is often planted in Danish 

 gardens and forests, and is quite hardy. 



It is said to thrive well at Drontheim (Trondhjem) in Norway, and 

 trees of from 1 to 2 feet in height have even done well at Hernsand 

 (62° 380 (" Tidning for Tradgardsodlare," Stockholm, 1878 and 1880).

Habitat. — North Africa. Kabylia in Algiers ; near the summit 

 and on the northern aspect of Mounts Tababor and Babor, at an 

 elevation of from 4,000 to 6,000 feet, sparingly interspersed with 

 the Mount Atlas Cedar. 



Introduced into Franco in 1862 by Davont, and in 1864 by 

 De Lannoy, superintendent of roads and bridges in the province of 

 Constantia ; and subsequently received in England. It was discovered 

 in 1861 by Captain de Guibert. 



Several young plants have done well in Denmark, and do not seem 

 to have suffered in any way from the severe winter of 1890-91.

Habitat. — In the mountain districts of Central and Southern 

 Europe (sparsely in the Apennines), as far westward as the Pyrenees, 

 and extending eastward to the Transylvanian Alps, the Carpathians, 

 and the Caucasus. Its northern limit is about lat. 50°, beyond which 

 it is found only in cultivation.
