THE FEYER TREE. 



The blue gum, Eucalyptus glob- 

 ulus, which has been so widely in- 

 troduced as a forest tree into Af- 

 rica, Southern Europe and Cali- 

 fornia, has gained its popularity 

 mainly because of its rapid growth 

 and the facility with which it 

 adapts itself to the country. But 

 it possesses other claims for exis- 



tence because of its alleged anti- 

 febrile properties; and has re- 

 ceived the name of fever tree in 

 consequence. Its introduction in- 

 to Texas in 1875 demonstrated its 

 adaptability to the coast cities of 

 the Gulf of Mexico, which are pe- 

 riodically subject to severe yellow 

 fever epidemics, where this tree 

 by its great property of absorp- 

 tion is thougl it to absorb the ma- 

 laria of marshy districts and ren- 

 der them inoccuous in that way. 



Its tall, graceful aspect and the 

 pleasant spicy odor which perme- 

 ates the air in its vicinity makes 

 the Eucalyptus agreeable both as 

 an ornamental and as a forest tree ; 

 and with the additional guaran- 

 tee of protection from fever epi- 

 demics, firmly established by fur- 

 ther experiments, must cause its 

 popularity to be undiminished for 

 many years to come and render it 

 particularly desirable for the coast 

 regions of Mexico. 



The fever tree was introduced 

 into Paris, France, in 1860, by di- 

 rection of the government, and 

 subsequently large forests planted 

 in Africa, Spain and Italy, and it 

 deserves even greater attention 

 from health commissioners and 

 those studying the important prob- 

 lems of health, the result of whose 

 investigations must largely affect 

 the interests of the Mexican peo- 

 ple and those connected with her 

 commerce. 



Apparently very large trichinae, 

 about a half an inch long, have 

 been found in great numbers in 

 the tissues of a large wood duck 

 recently killed in Kansas, accord- 

 ing to a local paper.
