He had turned his hand, with his brain in it, to many things; he had been enterprising, in an eminent sense of the term; he had been adventurous and even reckless, and he had known bitter failure as well as brilliant success; but he was a born experimentalist, and he had always found something to enjoy in the pressure of necessity, even when it was as irritating as the haircloth shirt of the mediaeval monk.
