In this volume are presented examples of men who shed lustre upon ordinary pursuits, either by the superior manner in which they exercised them or by the noble use they made of the leisure which success in them usually gives. Such men are the nobility of republics.

Most of these chapters were published originally in "The Ledger" of New York, and a few of them in "The Youths' Companion" of Boston, the largest two circulations in the country. I have occasionally had reason to think that they were of some service to young readers, and I may add that they represent more labor and research than would be naturally supposed from their brevity. Perhaps in this new form they may reach and influence the minds of future leaders in the great and growing realm of business. I should pity any young man who could read the briefest account of what has been done in manufacturing towns by such men as John Smedley and Robert Owen without forming a secret resolve to do something similar if ever he should win the opportunity.
