This large and beautiful tree in the southern 

 forests attains the height of 100 to 140 ft. 

 with straight columnar trunk 4 or 5 ft. in 

 diameter. When isolated it develops a sym- 

 metrical oblong-pyramidal top when young, but 

 finally becoming broad and rounded. A pe- 

 culiar feature, more marked in some trees than 

 others, however, and often entirely wanting, is 

 the growth of wing-like projections of the 

 bark from its smaller branches. It thrives 

 best in the rich soil of bottom-lands where it 

 is associated with the Red and Black Maples, 

 the Sour, Water and Tupelo Gums, the Laurel 

 and W^ater Oaks, various Ashes, etc. Few 

 trees of the American forests equal the Sweet 

 Gum in ornamental value, owing to its grand 

 habit of growth and its beautiful star-shaped 

 leaves, of a rich green in summer and con- 

 spicuous in autumn on account of their crimson 

 and purple tints. 



The wood, a cu. ft. of which when absolutely 

 dry weighs 36.82 lbs., is rather soft, with 

 .straight close grain, and is used in the maiui 

 facture of wooden-ware, paving-blocks, lumber 

 for general construction, etc., and is sometimes 

 marketed under the absurd names — Satin 

 ^Valnut, California Red Gum, etc.i
