IN EXTRA-TROPICAL COUNTRIES. 



Acer campestre, Linne. 



The British Maple. Extends from Middle Europe to North Asia. 

 Height 40 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 hedge-growth. 

 Comparatively quick of growth, and easily raised from seed. 

 These remarks apply to many kinds of maples. 



Acer circinnatum, Pursh. 



Tlie Vine-Maple of North- West America, forming in Oregon 

 impenetrable forests on account of its long branches bending to 

 the ground and striking root. The stem is sometimes 40 feet long, 

 but slender. The wood is heavier and of closer grain than that of 

 A. macrocarpum (Dr. Gibbons). 



Acer dasycarpum, Ehrhart. 



The White Maple of North America. Likes rather a warmer 

 climate than the other American Maples, and therefore particu- 

 larly desirable for us here. Height 50 feet ; wood pale and soft, 

 stem sometimes 9 feet in diameter. Much praised for street- 

 planting ; growth comparatively rapid. It 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 Red Maple takes its place. The wood is of less 

 strength and durability than that of its congeners, but produces 

 excellent charcoal. It may be cut into extreme thinness for wood- 

 paperhangings (Simmonds). The tree also yields Maple-sagar, 

 though not in such quantity as A. saccharinum. 



Acer macrophyllum, Pursh. 



Large Oregon-Maple. From British Columbia to North Mexico. 

 Tree up to 90 feet high, of quick growth ; stem attaining 16 feet 

 in circumference ; wood whitish, beautifully veined. A fine shade- 

 tree ; delights on banks of streams. The inner bark can be 

 utilised for baskets, hats, and superior mats ; the hard and close 

 wood is a substitute for hickory. The curled wood is splendid 

 for ornamental work. Maple-sugar is manufactured from the sap 

 (Sargent). 



Acer Negundo, Linne. 



The Box-Elder of North America. A tree, deciduous like the rest 

 of the Maples ; attains a height of about 50 feet, and is rich in 

 saccharine sap ; according to Yasey it contains almost as much as
