cussions accumulate, and after a time concur with other causes in producing that state of disability called nervous exhaustion. An observant man may see on one side of any stone or brick sidewalk in the city wherever there is soft ground near by, a well-worn path which will be instinctively chosen by pedestrians. If we test ourselves we shall find the chief reason of our choice is because it jars us less to walk there than upon stones and bricks.
Most healthy men endure these concussions for a long time without very serious effects, while others who suffer from them are entirely restored by enforced rest, provided the circulation be at the same time maintained. It is not improbable that some of the long cobweb-like processes of the nerve-cells are damaged by being shaken for months and years over city pavements.
Statistics upon such a matter are almost out of the question where insufficient exercise, noise, and jarring of the nerve-centers combine with other influences to overthrow the individual or to lessen his productive powers.
If it be then injurious to some to walk daily for years upon stones and bricks, and less so upon earth or softer material, this can be remedied in two ways. First, by changing the material of our sidewalks to a more elastic one. Something is needed for pedestrians which will be durable, yet not hard. Some of the varieties of asphalt composition are elastic, but none of them sufficiently durable, as far as I know.
Nature suggests a remedy in a second way, in the covering of the human heel itself where we find a very elastic pad one half an inch thick, to lessen the jar of walking. If we replace the perfectly hard boot-heel by an elastic India-rubber one, we provide an inexpensive and practical remedy, which it would cost the wearer but a few cents a month to keep in repair. This cover has the additional advantage of lessening the noise of hurrying feet, and preventing broken bones in the winter season. If now our city authorities will, at some future time, provide gymnasia as well as libraries and parks, make our large towns quiet as well as clean, and give us sidewalks more like Mother Earth, we believe such a favored community will produce more, and lead collectively a happier life, than most of our modern towns.
