The old gray mare was not the ecological marvel, in American cities, that horse lovers like to believe

To many urban Americans in the 1970’s, fighting their way through the traffic’s din and gagging on air heavy with exhaust fumes, the automobile is a major villain in the sad tale of atmospheric pollution. Yet they have forgotten, or rather never knew, that the predecessor of the auto was also a major polluter. The faithful, friendly horse was charged with creating the very problems today attributed to the automobile: air contaminants harmful to health, noxious odors, and noise. At the beginning of the twentieth century, in fact, writers in popular and scientific periodicals were decrying the pollution of the public streets and demanding “the banishment of the horse from American cities” in vigorous terms. The presence of 120,000 horses in New York City, wrote one 1908 authority for example, is “an economic burden, an affront to cleanliness, and a terrible tax upon human life.” The solution to the problem, agreed the critics, was the adoption of the “horseless carriage.”

European cities had shown concern for the problem as early as the fourteenth century, as had American cities from their beginnings. But it required a more statistically minded age to measure the actual amount of manure produced by the horse. Sanitary experts in the early part of the twentieth century agreed that the normal city horse produced between fifteen and thirty pounds of manure a day, with the average being something like twenty-two pounds. Ina city like Milwaukee in 1907, for instance, with a human population of 350,000 and a horse population of 12,500, this meant 133 tons of manure a day, for a daily average of nearly three-quarters of a pound of manure for each resident. Or, as health officials in Rochester, New York, calculated in 1900, the fifteen thousand horses in that city produced enough manure in a year to make a pile 175 feet high covering an acre of ground and breeding sixteen billion flies, each one a potential spreader of germs. 

Milwaukee and Rochester resembled other American cities in 1900 in having thousands of horses at work in their streets even after the automobile and electric streetcar had been introduced. Chicago had 83,330, Detroit 12,000, and Columbus 5,000. Overall, there were probably between three and three and a half million horses in American cities as the century opened, compared with about seventeen million living in more bucolic environments. (Today, at a time when horseback riding for pleasure is on the rise, the total number of horses in the United States is somewhat over seven million.) The ratio of horses to people was much higher in cities where traction lines were not yet completely electrified. In 1890, even after electrification had already begun, twenty-two thousand horses and mules were still required simply for pulling streetcars in New York City and in Brooklyn, with a total of ten thousand performing similarly in Philadelphia and Chicago. Ten years earlier, when New York and Brooklyn had counted no electric railways and 1,764,168 souls, they had a total equine population of 150,000 to 175,000.
