The record of the next three years only traces a slow, steady strengthening of my position. Not one of us had any set-back through sickness because I considered our health as so much capital and guarded it as carefully as a banker does his money. I was afraid at first of the city water but I found it was as pure as spring water. It was protected from its very source and was stored in a carefully guarded reservoir. It was frequently analyzed and there wasn't a case of typhoid in the ward which could be traced to the water. The milk was the great danger down here. At the small shops it was often carelessly stored and carelessly handled. From the beginning, I bought our milk up town though I had to pay a cent a quart more for it. Ruth picked out all the fish and meat and of course nothing tainted in this line could be sold to her. We ate few canned goods and then nothing but canned vegetables. Many of our neighbors used canned meats. I don't know whether any sickness resulted from this or not but I know that they often left the stuff for hours in an opened tin. Many of the tenements swarmed with flies in the summer although it was a small matter to keep them out of four rooms. So if the canned stuff _didn't_ get infected it was a wonder. The sanitary arrangements in the flat were good, though here again many families proceeded to make them bad about as fast as they could. These people didn't seem to mind dirt in any form. It was a perfectly simple and inexpensive matter to keep themselves and their surroundings clean if they cared to take the trouble. Then the roof contributed largely towards our good health. Ruth spent a great deal of time up there during the day and the boy slept there during the summer. Our simple food and exercise also helped, while for me nothing could have been better than my daily plunge in the salt water. I kept this up as long as the bath house was open and in the winter took a cold sponge and rub-down every night. So, too, did the boy. For the rest, we all took sensible precautions against exposure. We dressed warmly and kept our feet dry. Here again our neighbors were insanely foolish. They never changed their clothes until bed time, didn't keep them clean or fresh at any time, and they lived in a temperature of eighty-five with the air foul from many breaths and tobacco smoke. Even the children had to breathe this. Then both men and women went out from this into the cold air either over-dressed or under-dressed. The result of such foolishness very naturally was tuberculosis, pneumonia, typhoid and about everything else that contributes to a high death rate. Not only this but one person suffering from any of these things infected a whole family.
