eter and 40 feet high; an E. iereticornis of the same age was 30 feet 

 . high and 8 inches in diameter; and E. rostrata trees of this age 

 were 35 feet high and 10 inches in diameter. In Phoenix, at the 

 corner of Adams Street and Ninth Avenue, is an £. ro^/ra/a 16 years 

 old, which is about 90 feet high and over 3 feet in diameter 5 feet 

 from the ground. 



Eucalypt trees have been thorough!}^ tested at the Experiment 

 Station Farm at Phoenix and have been planted to a considerable 

 extent in the Salt River and Colorado River valleys. They are 

 better adapted to conditions in the Colorado River Valley than to 

 those of the Salt River Valley. Of the 50 or 60 species tested 

 at the Station Farm only 4 or 5 have proven well adapted to our 

 climatic conditions. Of these. Eucalyptus rudis, E. tereticornis, 

 and E. rostrata are among the valuable ones of the genus. Euca- 

 lyptus rudis was planted sparingly in the Upper Gila Valley and 

 succeeded well during a few moderately favorable seasons. With 

 rather cold weather the foliage was killed, and during a recent 

 cold winter all the trees were killed to the ground. In the Santa 

 Cruz Valley about Tucson, Eucalyptus rudis, E. rostrata, and E. 

 polyanthema have made splendid growths and for a number of 

 years were very promising for ornamental and economic purposes. 

 Occasionally they were injured with the coldest weather, but this 

 "was not regarded as serious. During the winter of 1912-1913 the 

 Eucalypt trees about Tucson were killed back seriously by the 

 severe freezes, the lowest temperatures being 6° F. above zero. 

 Since then they have not been planted extensively. 



Eucalypt culture will probably never prove a success as a saw 

 log industry in any part of Arizona. By planting the hardy spe- 

 cies noted above, however, timber can be grown for fuel, fence 

 posts, and, perhaps, for telegraph poles, railroad ties, and other 

 purposes for which durable hardwood timber is used. In Arizona 

 we must expect occasional severe winters which will materially 

 damage Eucalyptus trees and result in the wood being harvested 

 even in an immature condition, since fresh growth will begin from 

 the base.
