in Extra-Tropical Countries. 11 



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 pale and soft, of less 

 strength and durability than that of many of its congeners, but makes 

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

 paperhangings (Simmonds). The tree also yields maple-sugar, though 

 not in such quantity as A. saccharinum. With other maples, an 

 early yielder of honey to bees. 



Acer macrophyllum, Pursh. 



Large Oregon-Maple. From British Columbia to Northern 

 Mexico. A fine shade-tree of quick growth; sometimes reaching a 

 height of 90 feet; stem attaining 16 feet in circumference; wood 

 whitish, beautifully veined; delights on banks of streams. The 

 inner bark can be utilized for baskets, hats and superior mats; the 

 hard and close wood is a substitute for hickory. The wood when 

 curled is splendid for ornamental work. Maple-sugar is also manu- 

 factured from the sap of this species (Sargent). 



Acer Neglindo, Linne. (Negundo aceroides,M.oench.) 



The Box-elder of North-America. Hardy in Norway to 59 55' 

 N. (Schuebeler). A tree, deciduous like the rest of the maples; may 

 attain a height of about 50 feet, and is rich in saccharine sap; 

 according to Vasey it contains almost as much as the Sugar-maple. 

 In California it is used extensively as a shade-tree. Cultivated, the 

 stem attains about 8 inches in diameter in 8 years (Brewer). The 

 wood is yellow, marked with violet and rosy veins (Simmonds). 

 Rate of stem- girth in Nebraska about 2 feet in fourteen years 

 (Governor Furnas). 



Acer niveum, Blume. 



Continental and Insular India, up on the forest-ranges. This is 

 the tallest of the maples, attaining a height of 150 feet. Several 

 other large maples, worthy of cultivation particularly in parks, occur 

 on the mountains of India. 



Acer palmatum, Thunberg. 



Japan. A beautiful tree, with deeply cleft leaves; various varie- 

 ties with red- and yellow-tinged leaves occur. Unhurt by frost at 

 F. (Gorlie). Should it be an aim, to bring together all the kinds of 

 maples, which could be easily grown in appropriate spots, then Japan 

 alone would furnish 22 species. 



Acer pictum, Thunberg. 



From Persia to Japan. Ascending the Himalayas to 9,000 feet. 

 Foliage turning yellow and red in autumn. Wood close-grained and 

 elastic, particularly sought for load-poles, ploughs, chairs and various 

 implements and utensils (Brandis); twigs lopped off for fodder 

 (Gamble).
