There was, no doubt, talk about passing laws to halt the growth, and even laws limiting the size of horses that could be used for various purposes. Certainly governments should keep those pesky cars and buses out of the city because they scared the horses. Eventually, the urban planners went home in a gloomy mood. Their mistake was that they assumed, as planners usually do, that the trend would go forward as in the past, and that only new laws limiting the number of horses could solve the horse manure crisis.
But out in the free marketplace innovators and entrepreneurs spotted an opportunity ... Henry Ford, Gottfried Daimler and others. And as it became more costly to maintain a horse in the city, cars and buses and electric trolleys did what urban planners could never envision: they solved the Great Horse Manure Crisis of 1894. Every now and then I think we've got something we can learn from history.
