60 MONTANA EXPEEIMENT STATION 



In Dr. McClintic's own words, 'It was decided to select a limited 

 area in one of the worst infected territories, and to put into operation 

 the best known methods for the eradication of the tick. An infected 

 area of eight square miles was selected near Victor, Montana (in 

 the Bitter Root Valley). The work was carried on at Victor from 

 May until August when the laboratory side was continued in the 

 Hygienic Laboratory at Washington.' The eradication of the tick 

 was accomplished in the selected district by dipping domestic ani- 

 mals and stock in an arsenic mixture, and by killing wild mammals. 



"Dr. McClintic soon became the leading authority on tick fever. 

 He did valuable work in search of a curative or preventive serum. 

 In March, 1912, he was married to Miss Theresa Drexel of Wash- 

 ington, D. C, and soon thereafter returned with his bride to Victor 

 in readiness for the tick season. In midsummer he was taken sick 

 with the disease which claimed his life. No case of spotted fever 

 has developed in the Bitter Root Valley this year. Doctor McClintic 

 had driven the pestilence out. But as it went, it struck down the 

 man who had conquered it." 



In "The Human Factor," published by the Equitable Life 

 A.ssurance Society, New York, December, 1912, occurs what is 

 apparently a review of the article in the "Outlook," as follows : 



"The perils of war against epidemic disease are frequently 

 emphasized by the loss of brave and efficient soldiers of science on 

 the advanced firing-line. 



"Yellow fever, smallpox, typhoid, cholera and other infections 

 have struck down many physicians and sanitarians engaged in com- 

 bating them. A number of members of our splendid national health 

 corps have been fatally attacked by the enemy they were successfully 

 pursuing. 



"The most recent instance where a member of the National 

 Public Health Service lost his life in a hand-to-hand struggle with 

 infectious disease, is that of Dr. Thomas Brown McClintic, the 

 leading authority on Rocky Mountain spotted fever. 



"For many years this peculiar disease had been prevalent in 

 the Rocky Mountain States, and every spring it had claimed an 

 increasing toll of lives. 



"According to Dr. Alfred C. Reed, another member of the Public 

 Health Service, spotted fever has been especially virulent in the
