CHICAGO: DUNCAN BROTHERS. 1880. SOIL AND WATER POLLUTION. There is no subject of greater interest to the people than that of health and the best means of obtaining it. Plenty of wholesome food, good air and pure water constitute the first essentials of right living. Any thing which contaminates these prime requisites admits a factor into the problem of life which seriously vitiates its result. To what extent agents of adulteration have injured the human family by disease and death we do not know, but the usual estimate made by sanitarians is, that nearly one-half of the existing diseases might be abolished, provided that individuals and communities should enter upon correct modes of living. In the United States over one hundred thousand persons die annually, and probably one hundred and fifty thousand persons are constantly sick from causes well known to be preventable. Dr. Draper says the total number of deaths in Massachusetts during five years, 1869-73, from all causes was 156,289; of that number the deaths from zymotic or fermentable diseases comprised 26 per cent.; those from acute pulmonary diseases were 7 per cent.; and those from phthisis, 17 per cent. So that, if we include all these among the “preventable” diseases, the deaths from these causes represent one-half the actual mortality. It is estimated that the productive efficiency of the average life in this country might be increased 30 per cent.; or up to the normal amount by the proper observance of health laws. The annual mortality rate should not exceed 15 per 1,000 in cities under good sanitary management, but the tables of the National Board of Health show a greater mortality in almost every city of the country. Zymotic or preventable diseases are increasing in Indianapolis. From these diseases 443 deaths occurred in the city during the year 1879—over 32 per cent. more than in 1878—and if such a large number died, it is fair to calculate that twenty times as many persons were more or less sick from the same causes. Nearly 33 per cent. of the total deaths of the city last year were due to zymotic diseases. These facts should awaken the public to thorough search for the causes at work producing such a high mortality.
