inoculation of blood from the sick to the well. 

 The disease is not air borne, nor is it carried in 

 clothing, books or other such articles. The 

 mosquitoes must be destroyed in order to pre- 

 vent the spread of the disease. To return to the 

 work of the yellow fever commission: The 

 experiments of the American workers. Reed 

 and Carroll, and their assistants Agramonte 

 and Lazear, brought to light positive proof of 

 the part the mosquito, stegomyia fasciata, 

 plays in the rise and spread of yellow fever. 

 The yellow fever commission was appointed by 

 the Surgeon General of the United States Army 

 to carry on a work of investigation at Havana, 

 Cuba, in the year 1900. It has been proven 

 through the efforts of this commission that the 

 unknown germ of yellow fever is transmitted Transmitted, 

 from the sick to the well through the bite of 

 just this one type of mosquito and has also made 

 clear the Utter futility of attempts at circum- 

 scribing the disease by means of disinfectants. 

 These men have successfully demonstrated that ^^^ Blood 

 the blood is the only avenue of escape of the Only Avenue 

 germ and that in no other way than through the ° ^'^^^^' 

 agency of stegomyia fasciata can the infected 

 blood be carried and transmitted. Therefore, 

 use of disinfectants must be valueless and 

 destruction of the mosquito, stegomyia fasciata, 

 the only solution of the yellow fever problem.
