44. (157.) Fraxinvs viridis. Greeu Ash. 



Not uncommou in wet woods ; uo measurements. 



45. (165.) Catalpa speciosa. Catalpa; "Patalpha"; "Wahoo." 

 Formerly abundant in rich bottom lands, but now nearly exterminated 



in many localities. Trees of 100 feet or more in height were formerly 

 not uncommon, while a diameter of 4J feet has been reported (see Cox's 

 Geological Purvey of Indiana, 1873, p. 417). The usual dimensions, 

 however, are, for the larger trees, 70 to 00 feet high, and 2J to 3 feet 

 diameter. It is usually, however, decidedly smaller, and when growing 

 in open situations forms a low spreading tree, seldom more than 50 feet 

 in height, and frequently much less. Trees of this character were form- 

 erly very abundant in the bottoms about a mile above Mount Carmel, 

 but they have nearly all been cut for fence-posts. 



In Posey County, Indiana, while making inquiries of an intelligent 

 gentleman regarding the timber of his neighborhood, 1 was informed 

 that the day before he had cut a Catalpa, the trunk of which produced 

 eight 7 foot post-cuts, the diameter at the base being 4 feet, while the 

 total length of the tree he estimated at about 130 feet. 



Blossoms late in May or early in June (seen in full bloom near the O. 

 and M. K. R., between Shoals and Huron, Indiana, May 30, 1881.) 



46. (171.) Sassafras officinale. Sassafras. 



Yery common, and in rich woods growing to a large size. The lumber 

 of this tree is more highly prized than any other for skiffs, being light, 

 strong, and durable. It is also much used for fence-posts and rails. 

 Although averaging perha]^s not more than 50 feet in height and a foot 

 in diameter it is occasionally much larger, reaching in rare instances a 

 diameter of 4 feet. The largest trees measured by me, however, were 

 nnich less, being respectively, 7, Ih, and 7f feet m girth ; the last 00 

 feet high, with a clear trunk of 30 feet; the second 95 feet high, with a 

 trunk 75 feet long. 



47. (176.) Ulmns alata. Winged Elm. 



A rather rare tree, chiefly in river bottoms and along banks of 

 streams; no measurements.
