The White Ash is one of the most valuable 

 hardwood trees of the American forests, and 

 one of the statliest representatives of its genus. 

 In the forests of the rich bottom-lands of the 

 lower Ohio basin it has been known to attain 

 the height of 120 ft. and 5-0 ft. in diameter of 

 trunk, but these dimensions are exceptional. 

 It occupies rich slopes and bottom-lands, where 

 not too moist, and is an abundant tree through- 

 out most of the eastern states and Canada. 

 When growing apart from other trees it de- 

 velops an ovoid or somewhat pyramidal top, 

 Avith long slender lateral branches. It is a 

 tree of good habit and handsome foliage and 

 is popular as an ornamental shade tree. 



The wood of the \Miite Ash is heavy, a cubic 

 foot weighing 40.78 lbs., hard and strong, and 

 is used extensively in the manufacture of tool- 

 handles, agricultural implements, cars, furni- 

 ture, etc.i The inner bark is used in medicine.

 olate, ovate or obovate petiolulate leaflets, rounded
