I have never known a concern to make a decided success that did not do good, honest work, and even in these days of fiercest competition, when everything would seem to be a matter of price, there lies still at the root of great business success the very much more important factor of quality. The effect of attention to quality, upon every man in the service, from the president of the concern down to the humblest laborer, cannot be overestimated.
