more rapid than that of A. alba under similar circumstances.

Engyravings. Lamb. Pin., ed. 2., 1. t. 38.; Wang. Beyt., t. 16. f. 54.; and our fig. 1930. 
Spec. Char, §c. Leaves solitary, awl-shaped, acuminate. Cones oblong, 
blunt; scales round, somewhat 2-lobed, entire. (Lamb. Pin.) Leaves little 
more than 2 in. long ; slightly tetragonal. Cones about 1 in. long, and 2 in. 
broad; scales notched. Seeds very smail. A large tree. Nova Scotia, 
and about Hudson’s Bay. Height 70 ft. to 80 ft. Cultivated in England 
before 1755. Flowering in May, and ripening its cones the following spring. 
Variety. A. (n.) 7.2 
cerilea, A. ceertilea 
Booth.— Has glau- 
cous leaves, and 
appears to us to 
differ from A. (n.) 
rubra only in the 
colour of the cones. 
The cones are ra- 
ther longer and red- 
der than those of A. 
nigra, and covered 
with resin. Michaux 
says that the red 
spruce is in no way 1930. A. (n.) rubra, 
inferior to the black 
spruce in the quality of its timber, which “unites in the highest degree all 
the good qualities that characterise the species.” He also states that, instead 
of being a low tree, it is superior in size to 
the black spruce, as it generally grows in 
richer soil; and that the wood is reddish, 
instead of being white. In Lawson’s Manual, 
it is stated that A. ribra differs essentially 
both from A. nigra and A, Alba in all its 
parts; and particularly in its leaves, which 
are more slender and sharper-pointed than 
in either of these species.
