Somewhere on the West coast of England, about a hundred miles from the metropolis, there stands a sleepy little town, which possesses no special activity nor beauty to justify its existence. People live in it for reasons of their own. The people who do not live in it wonder for what reasons, but attain no better solution of the mystery than the statement that the air is very fine. "We have such bracing air!" says the resident, as proudly as if that said air were his special invention and property.
