Acer campestre, Linné.
The British Maple. Extends from Middle Europe to North
Asia. Height forty feet, in shelter and deep soil ; the yellow
and purple tints of its foliage in autumn render the tree then
particularly beautiful. The wood is compact and fine-grained,
and sought for choice furniture. The tree can be trimmed
for bedge-growtli. Comparatively quick of growth, and easily
raised from seed. These remarks apply to many kinds of
Maples.
Acer dasycarpum, Ebrbart.
The White Maple of North America. Likes rather a warmer
climate than the other American Maples, and therefore particularly
desirable for us here. Height fifty feet; wood pale
and soft, stem sometimes nine feet in diameter. Much
praised for street-planting; growth comparatively rapid. I t
produces no suckers, nor is the tree subject to disease. A
most beautiful tree, with a stout stem and a magnificent
crown, growing best on the banks of rivers with limpid
water and a gravelly bed, but never in swampy ground,
where the Bed Maple takes its place. _ The wood is of less
strength and durability than that of its congeners, but produces
excellent charcoal. The tree also yields Maple-sugar,
though not in such quantity as A. saccharinum.
