M. L.-Deslongchamps says that it has a strong resemblance to the 
wood of the pine, and still more to that of the fir; that the section of 
the trunk of a cedar is more like that of a silver fir than any other 
resinous tree. ‘‘ The wood of the cedar,’ says this author, “ burns 
quickly, crackling a great deal, and does not give as much heat as 
the oak, hornbeam, wych elm, or beech; its charcoal is very light, 
and yields very little heat, and is quickly reduced to ashes, like that 
of the poplar and the willow.” Loudon, who was in a position to 
gather a great deal of information on the subject, since the cedar 
was cultivated sooner and in much larger quantities in England 
than in France, says (Arboretum, vol. iv., p. 2417)—“ the wood of 
the cedar is of a reddish-white ; light and spongy, easily worked, 
but very apt to shrink and warp, and by no means durable. A 
plank of cedar compared with planks of Scots fir grown in England, 
was found to be inferior to them in strength.” 
Diseases and Accidents.—In reference to these I cannot do better 
than quote the words of Loudon (Arboretum, vol. iv., p. 2425) :— 
“The strong and spreading branches of the cedar are liable to be 
broken by the weight of the abundant snow which sometimes over- 
whelms them; but this tree is less liable to be blown down by the 
wind than the pine, fir, or larch, which have not, as this has, large 
and strong branches near to the ground. It is not subject to 
disease, and from what we have observed is less liable to be attacked 
by insects than any other species of the pine tribe.” 
Cedrus atlantica.—I believe that only two authors have yet 
written on the Silver, or Mount Atlas Cedar—M. Renou, in his 
‘“‘ Notice sur les foréts de Cédres de l’Algérie,” from which I have 
quoted some passages; and M. Durien de Maison-Neuve, Mem- 
ber of the Scientific Commission of Algiers, The observations of 
M. Durien were transmitted to the Academy of Science by 
M. Bory, of St Vincent, in a memoir entitled “Sur les Cédres 
de l’Atlas et l'emploi de leur bois dans les constructions mauresques 
d’Alger ;” and this memoir has been inserted in the Compte rendu 
des séunces de ?Académie Sciences, vol. xviii., No. 24 (June 10, 
1844). 
Loudon, in the article on ‘ Cedrus Libani” (Arboretum, vol. iv., 
p. 2402), mentions a variety Foliis argenteis, but he says that the 
leaves are of a silvery colour on both sides, while those of the Silver 
Cedar of Algeria have this colour only on the under side. He adds 
that there are some beautiful trees of it at Whitton and at Pains 
Hill, and he is astonished that the nurserymen have never taken
