The Cork Elin attains the height of 80-100 

 ft., with trunk 3 or 4 ft. in diameter, and in 

 forests has a straight columnar trunk some- 

 times free from branches to the height of 60 

 or 70 ft. When growing outside of the forest 

 its habit of growth is generally quite different 

 from that of the White Elm, as it develops a 

 rather narrow oblong top with strongly droop- 

 ing lateral and lower branches and corky- 

 winged branchlets, as shown in our trunk pic- 

 ture. 



It is a tree inhabiting uplands, rocky ridges 

 and slopes, in company with the Sugar Maple, 

 Hop Hornbeam, Butternut, Basswood, White 

 Ash, Beech, etc., but is much less abundant 

 and general in its distribution than the White 

 Elm. 



Its wood is heavy, a cubic foot weighing 



when absolutely dry 45.2.'5 lbs., and is especially 



sought where great strength, toughness and 



flexibility are required, as in the manufacture 



of heavy agricultural implements, the handles 



of tools, etc.2 



Leaves obovate-oblonsr, narrow and obtuse to 

 subcordate and somewbat inequilateral at base, 

 doubly serrate, with usually incurved teeth, 

 smoolih lustrous dark green above, pale pubescent 

 beneath : petioles and branchlets pubescent ; buds 

 taper-pointed with puberulous ciliate scales. 

 Ploioers in racemes with slender filiform jointed 

 pedicels ; calyx 7-S-lobed ; anthers purple. Fruit 

 ripening when the leaves are about balf grown, 

 samarie obovate-oblong, pale, obscurely nerved, 

 pubescent and i-ilinte.
