The somewhat rough estimate given of the number of volumes written by the respective writers indicates that Mr. Bancroft's revisions constitute about one page in fifty of the work in fields assigned to his assistants, although the average may be lower. In view of these facts, the knowledge that those who wrote the Bancroft histories were capable, honest persons, must tend decidedly toward the increasing of our general confidence in the series.
