and hate, commerce, industry, government every 

 topic which holds men's minds all being transmitted 

 through a common medium, none necessarily interfering 

 with any other. Surely the imagery of the past seems 

 trivial when compared with the reality of to-day. 



Science has successfully attacked many of the ills to 

 which men succumb. We need not now have smallpox 

 unless we prefer not to do the things which science has 

 shown will prevent this disease. Typhoid, far less 

 common than two decades ago, is so well understood 

 and its transmission so definitely associated with un- 

 cleanliness that we shall soon see the day when it will 

 be not only unfortunate but not respectable to have the 

 disease. It would now be more indecent to have 

 typhoid than it is to have the "itch," were each person 

 as fully in control of his own personal environment for 

 cne one disease as for the other. Yellow fever, the 

 awful plague of many countries, not only can be de- 

 stroyed, but has actually been destroyed in certain of 

 its worst centres. It is a picturesque campaign now 

 Deing waged, one with a vision of service to the human 

 race, to remove yellow fever from the earth. The most 

 dreaded disease of all, perhaps, tuberculosis, is slowly 

 but surely yielding. Though big tasks are ahead, 

 enough is now known and proved in practice with tu- 

 berculosis patients to give abundant hope to hundreds 

 of thousands of discouraged people who have this dis- 

 ease. It is but a brief time since a clear diagnosis of 

 tuberculosis was all but a death warrant. Surely sci- 

 ence is making the earth a better home for men.
