It being unlikely that any two editors would choose the same volumes for reprint, criticism of our list will undoubtedly be made. It should, however, candidly be explained that the matter of selection has in each case necessarily been affected by two important considerations—(1) the intrinsic value of the original from the historical side, and (2) its present rarity and market value. The Editor having selected a list of items worthy of a new lease of life, the Publishers, from their intimate knowledge of the commercial aspect of rare Americana, advised which of these in their opinion were sufficiently in demand by libraries and collectors to render the enterprise financially productive. It is believed that this co-operative method has resulted in an interesting collection, and given point to the descriptive sub-title: “Some of the best and rarest contemporary volumes of travel ... in the Middle and Far West, during the period of early American settlement.” The first volume of our series is necessarily more varied in composition than any of its successors, it having been deemed important to present herein several typical early tours into the Indian country west of the Alleghenies. That of Conrad Weiser, occurring in August and September of 1748, was the first official journey undertaken at the instance of the English colonies, to the west of the mountain wall. His purpose was, to carry to the tribesmen on the Ohio a present from the Pennsylvania and Virginia authorities. The results were favorable to an English alliance, but they were partially neutralized by the French expedition headed by Céloron the following year. The journals of George Croghan (1750-65) are an epitome of the Indian history of the time. The first three documents deal with the period of English progress—in 1750, Croghan was on the Ohio en route to the Shawnee towns and Pickawillany; the next season, he outwitted Joncaire on the Allegheny. The four succeeding documents are concerned with the period of hostility to the English—in 1754 he was on the Ohio after Washington had passed (December, 1753); the letter from Aughwick, in 1755, tells of affairs after Braddock’s defeat; in 1756, we learn particulars of Indian affairs; and in 1757 is given a résumé of past events. The last two journals are the longest and most important—that of 1760-61 is concerned, topographically and otherwise, with the trip to Detroit via Lake Erie, in the company of Rogers’s Rangers, and the return by land to Pittsburg; that of 1765, with a tour down the Ohio towards the Illinois, where the writer is captured and carried to Ouiatanon—in due course making a peace with Pontiac, and returning to Niagara.
