Economic uses. Wood hard, close-grained, strong, brittle, pale 

 brown. Uses same as those of the red maple. Lumber dealers 

 put the red and silver maple into one class and designate them as 

 soft maple. On drying the soft maples do not warp as much as 

 the hard maple. 



Horticultural value. Same as the preceding.

 Hard Maple. Rock Maple. Plate 112. Bark of young trees and 

 branches light brown, smooth or rough, becoming on old trees a 

 gray or dark brown, fissured, tardily separating into rather thick

 glossy, ridge of leaf scars slightly pubescent; leaves more or less 

 cordate at the base, usually 3-lobed, sometimes 5-lobed, 6-12 cm. 

 (23^-4^ inches) long, hairy beneath when young, becoming smooth 

 at maturity, rarely remaining pubescent, dark green above, whitish

 glabrous, 2-3 cm. (^-134 inches) long, wings diverging. 



Distribution. Newfoundland south to Georgia and west to Mani- 

 toba, Nebraska and Texas. Frequent to common in all parts of 

 Indiana in rich and well drained uplands. It is usually associated 

 with the beech and black maple. 



The published records of the distribution are as follows: Clark 

 (Baird and Taylor) and (Smith); Dearborn (Collins); Delaware
