are all sorts of symptoms of diagnostic import: Does an applicant for 
professional service use sedatives and narcotics (alcohol, tobacco, opium, ete.) 
and use them to excess, or, on the other hand, does he use stimulants (notably 
coffee and tea)? What does such use indicate? The statement is sometimes 
made that tobacco is the poor man’s friend, that after a hard day’s work he 
enjoys his pipe; it calms him. But when you study the poor man and the 
conditions under which he works, you can see that the great trusts may well 
make an effort to keep tobacco as cheap as possible. Offering Mr. Common 
People a cigar, especially one with a colored band, only too often makes 
him tolerate what are really intolerable conditions. Men working for some 
of the great trusts twelve hours a day, seven days a week, may be even too 
tired to smoke. Tobacco is also a great solace to the soldier in the trenches; 
it makes him contented, it dulls his mind and keeps him from thinking. 
CONIOSIS. 1911. As already mentioned, this paper is a general state- 
ment of the dust theory. My time limit is running to a close and I must 
refer you to the paper itself, which among other things treats our Triad of 
American Diseases (catarrh, dyspepsia, and nervous prostration) as reactions, 
similarly regarding blood pressure changes. The term disease at once 
brings to mind treatment, medicine, while reaction brings to mind pre- 
vention. 
CONIOLOGY. 1912. This paper was a plea for a new science and the 
need for an institution for working out problems. The dust particles 
emitted by the tobacco smoker are included. 
In 1913 I was unable to present my paper on RACE SUICIDE, in which 
the subject was also traced into the schools. There I asked, as this paper has 
already asked, regarding the use of tobacco by the teacher: Is he justified 
in using it? If he feels cross and irritable, shall he take something or do 
something—seek better air conditions, the proper construction of school 
buildings and proper ventilation and general cleanliness? Child mortality 
today is enormous. It should be greatly reduced, many bright children who 
now die could be saved to a life of usefulness. There is much truth in the 
old saying, The good die young. 
THE ALCOHOL PROBLEM IN THE LIGHT OF CONIOSIS. In 
my paper for 1914 the Tobacco Problem comes up on every page, and | 
believe after the remarks I have made you will readily see it. I mentioned 
how on entering medical school I found horribly bad air conditions. The 
drinking water was equally bad; it was raw muddy river water. A number
