20 EUCALYPTS CULTIVATED IN THE UNITED STATES. 



New Mexico, Texas, and Florida. In most cases the Blue Gum 

 {Eucalyptus globulus), the species that had been most successfully 

 grown in California, was the one first planted in these regions. The 

 Blue Gum is not adapted to these regions and this has led to the belief 

 that no Eucalypts would thrive there. In southern Arizona, for 

 example, the Blue Gum does not endure the dry heat of summer, while 

 in Florida the frosts of winter have been fatal to it. But in some of 

 these places more resistant species have been introduced and are grow- 

 ing satisfactorily. A more careful and systematic study of the genus, 

 accompanied by cultural tests, will undoubtedly result in the discovery 

 of additional and probably better species for these and other regions. 



Eucalypts have been introduced from California into Mexico also, 

 and their merits are being gradually recognized there. 



The introduction of heretofore untried species is continuing in the 

 Southwest, and the number grown there is thus rapidly increasing. 

 During the past three or four years especially a great many species 

 have been added to the list of those grown in America. The forty 

 species discussed at length in this publication comprise the species 

 known to the writer that have been introduced long enough to produce 

 seed, and thus establish their identity. Five years hence a large num- 

 ber of additional species will have fruited, and a publication covering 

 the s*mie ground that this one aims to cover would then include nearly 

 twice the number discussed in these pages. The recently introduced 

 species are growing mostly at the University of California, at forestry 

 stations at Santa Monica and Chico, on the ranch of A. Campbell- 

 Johnston (Garvanza), in Elysian Park (Los Angeles), and upon the 

 experiment station farm near Pho?nix. Their development is being 

 closely watched by those interested in their planting, and by whom 

 the great future possibilities in these recent arrivals from the native 

 home of the genus is fully realized. 



WRITERS UPON EUCALYPTS. 

 FOREIGN. 



Much has been written concerning this very interesting group of 

 trees. Most of the publications have been in English and in French — 

 several score in each language. A few have appeared in Italian, a few 

 in German, and a few in Spanish. 



The most comprehensive work on the Eucalypts is Baron von Muel- 

 ler's Eucalyptographia, a ten-part illustrated monograph, published 

 b} T the government printer at Melbourne, Australia, and by Trubner 

 & Co., London, 1879 to 1884. One hundred species are illustrated 

 and described, with their climatic requirements and their uses quite 

 fully given. Baron Von Mueller expressed in the final number a hope 

 that during the years remaining to him supplemental parts might be
