Why and wherefore the publication of this volume now? The answer is this: More than three-quarters of a century ago, one of the earlier biogra phers of Jefierson wrote: It would be a happy circumstance for America and for the mass of mankind if the works of Jefferson could obtain a circula tion which would place them in the hands of every individual. Unfortunately, the form in which they have appeared is not the most advantageous to the accomplishment of this desirable purpose. The publication is too voluminous, and consequently too expensive, to admit of a general introduction among all classes, nor is t/ze mode of arrangement the best adapted to its reception into ordinary use as a war/e of reference.
