THE MICROBE OF YELLOW FEVER 197 



Kill the larvae before they take wings and fly away. 



In countries, where the fever is endemic, govern- 

 ments should take hold of this matter in earnest. 

 Spare no expense. It is a wise and humane invest- 

 ment. It saves life! 



The French undertake to construct the Panama 

 Canal. The fever there is endemic. The workmen 

 are imported predisposed to the fever. They die 

 off in great numbers. The mortality is so great, 

 the job is abandoned. 



The United States buys the whole thing from the 

 French. The Yankees pry into the cause of the 

 fever, compel it to yield up its secrets. They im- 

 port their workmen. They protect them. They 

 fight the mosquito to kill. They screen the work- 

 men by night. They apply the kerosene by day. 

 The mosquitoes die. The workmen live. The great 

 enterprise is a success. The white man conquers 

 the tropics by conquering Stezzomia Fasciata. 



Make war upon the mosquito. Prevent the 

 fever. Lock the door!
