section, how shallow wells were infected. The water from the wells is used 
pecause it is clear. People prefer clear, sparkling water to muddy hydrant 
water, although the sparkling water may be veritable pcison. Where does 
the blame for typhoid fever rest? 
Still retracing my steps, I came to the neglected street with its weeds 
and with its corresponding class of people, going on to the heart of the city, 
with its lack of trees and full of sickly people. Then I compared or con- 
trasted the West End of town with the Hast End. The West End is the 
home of working people, while the Hast Ind is occupied mostly by trades- 
men and the well-to-do. Now our prevalent winds, as already mentioned, 
are from the west, and that means that the people in the West End get air 
from the woods and fields, while those in the East End get the smoke and 
dust from the shops and from the heart of the city. This may explain why 
the East End Wind has such an evil reputation, and why towns having the 
“West End” properly located are more desirable as places of residence. 
These remarks will be better understood when we consider that people, like 
herbaceous plants, but unlike trees, are mere or less constantly moving 
about. Some plants come and zo, they are seen one year and then dis- 
appear, perhaps to re-appear iater; those finding the habitat favorable may 
remain permanently. Common weeds find conditions favorable almost any- 
where and flourish, especially in neglected places. Shall we say that human 
weeds also thrive almost anywhere, and shall we say that people who are 
well-to-do and able to move do move out if they find that the “West End” 
has not been properly located? 
The subject may be considered a iittle further. Several years ago a 
patient with whom I had often discussed things like the above told me about 
meeting an old friend who had just returned from the Saskatchewan. The 
man gave a glowing account of the large crops of wheat, and the large 
potatoes, beets and turnips, all growing without weeds; he told how healthy 
the people were, they did not even have the common ailments; he ascribed 
it all to the “wonderful climate.” Climate nothing! my friend exclaimed ; 
weeds and ills and diseases are absent because they have not as yet been 
brought in. They will all come in time; just wait a few years. 
I might again refer to my old patient who had told me of early Indi- 
ana conditions and the coming in of weeds and pests and parasites of all 
kinds. He had also told me how healthy the first settlers were until 
malaria came in; then nearly everybody became sick. Life now assumed a
