Mr. W. leads a quiet isolated life on the farm ; has retired from active 

 work; is well-to-do. He lives in good air twenty-four hours a day. In 

 the summer when doors and windows are open he attends a country 

 church ; in winter when doors and windows are closed he remains at. home ; 

 says he can not bear close air. In recent years he comes to town about four 

 times a year ; formerly he gut sick on or after every trip, "would get faint 

 and dizzy and feel like falling," and friends only too often offered him a 

 drink of whiskey, to which he was opposed. When it was pointed out to 

 him that he was a marked dust victim he in time learned how to guard 

 himself; he no longer comes to town when dust clouds blow about and 

 spends little time in dusty buildings. 



Mr. H., an active farmer, lives in good air twenty-four hours a day, 

 that is as far as infection, found in city dust, is concerned. Sundays he 

 attends a village church. Occasionally he comes to town, perhaps 

 fifteen times a year ; his absences from home he thinks amount to about 

 seventy-five a year, varying from an hour or less to several hours. Former- 

 ly when he came to town he had an almost irresistible craving for strong 

 drink, i. e., on dusty days, as I soon found. He felt bad, was miserable ; 

 he learned that one or more drinks made him feel good, and only too often 

 the one or two drinks increased to a sufficient number to make him drunk ; 

 and then there was great remorse and he vowed never to drink again. 

 But until he learned tvhy he had such a craving, how it depended on in- 

 haling infected dust, he only too often could not resist the use of alcohol. 

 In the country when he was tired and would "spit cotton," water would 

 quench his thirst, but the phlegm due to spit dust required something 

 stronger "to cut it." 



Mr. X, a professional man, works in the heart of a city eight hours 

 a day for six days in the week. He wants to smoke all the time and fre- 

 quently wants a drink; at times he is on the verge of being drunk. The 

 desire for strong drink is almost irresistible "when there is strong mental 

 strain", as he supposed, but as a matter of fact it was at times of close 

 confinement to ill-ventilated offices and public buildings. Now the most in- 

 teresting phase in this man's history, the where, when and why, is this : 

 For two weeks or so every year he goes off to the northern wildwoods ; 

 then he has no desire for strong drink, scarcely touches it, and there is 

 little desire for smoking, that is, there is no excessive smoking. 



Mr. X, a business man, working, as he believed, "under high pressure."
