Not always driven by profit motive.

'War,' said I to myself, 'is the evil genius of a time; but good food for all is a daily and a paramount necessity.' These reflections led to a further communication with Messrs. Smith and Philips, of Snow Hill. I took out a patent for the stoves. This I did not like to do before I had introduced them to the Government, as every one would have supposed that I wished to make money by the patent. The object of a patent, after such a decided success, was to secure the solidity and perfection of the article. As it was difficult to make, and certain to be badly imitated, my reputation must have suffered. Instead of being expensive, they will be sold at a reasonable price, sufficient to repay the manufacturers, and to leave a fair profit; thus placing them within the reach of all — the million as well as the millionaire.
