from information furnished directly by the men who made this history, and that the lack of material which so often embarrasses the writer could not here be a cause of complaint, we may well conclude that such an opportunity had never before fallen to the lot of the historian.
Again, in the vast collection of historical sources into one place, as well as in the newness of the field and inspiring nature of the work, the undertaking presents a most remarkable feature. The projector of this enterprise was the first on the coast to undertake such a collection on a large scale. This fact, together with the recency of many of the events, which both rendered an unending number of eye-witnesses easily accessible for procuring personal narratives, and likewise caused those who possessed papers and books throwing light upon history, to set slight value upon them, enabled Mr. Bancroft to collect a library of material such as on the beginning and early chapters of Pacific Coast history in all probability can never again be equalled.
Finally, in the amount of material which it presents, and in the extent of ground which it covers, the Bancroft series has attained epoch-making proportions. So closely related is the history of the Pacific states and territories of the United States to that of the regions north and south, that to insure a complete understanding of it required the writing also of the History of Mexico, Texas, and Central America, as well as that of British Columbia and Alaska. When we learn that two thousand different authorities were consulted in writing the History of Central America, and ten thousand in arranging the material for the History of Mexico; that in taking out material for the History of California eight men were employed for six years; and that in merely indexing the material for the History of Mexico five men worked ten years, we are inclined to quote approvingly these words of Mr. Bancroft:
