It should be the privilege of every worker to take advantage of all the improved methods of working that relieve him from the tedium and fatigue of purely mechanical toil, for by this means he gains leisure for the thought necessary to working out his designs, and for the finer touches that the hand alone can give. So long as he remains master of his machinery it will serve him well, and his power of artistic expression will be freed rather than stifled by turning over to it work it is meant to do.
