After the completion of the two volumes on Oregon, Mrs. Victor's attention was next directed to the volume on Nevada, Colorado, and Wyoming. In the carrying on of this work, a greater number of suggestions as to manner of treatment were made by Mr. Bancroft, we may believe, than was usual in the preparation of a volume, for the reasons that it was hurried more for publication than earlier works, that it was written under his immediate direction, and that he himself collected and forwarded material from the field as required. The record of the progress of the work, as it occurs in Mr. Bancroft's letters to the writer of the volume, is of unusual interest in that the methods followed, though in some ways exceptional, may perhaps be taken as fairly typical of those employed by Mr. Bancroft in the preparation of the later volumes of the series which he immediately supervised. In August, 1884, shortly before the completion of the second volume of the History of Oregon, Mr. Bancroft went to Salt Lake City, where he left with Franklin D. Richards a memorandum to guide him in extracting material on the Mormons in Nevada which, he said, would be about the first material needed. Pending the arrival of this, on September 11th, he advised Mrs. Victor to familiarize herself with the history of Wyoming and Colorado, he himself having done the same for Nevada. A letter written a few days later presents the idea of making a plan of the volume "as the men do on Mexico, etc.," and says, "By so doing you can give each section its due proportion and by working to the plan save unnecessary labor." As to the method of treating early expeditions to Colorado and Wyoming, he says to consult the History of Utah, and the two opening chapters which he himself had already written on Nevada. When these chapters were prepared, it was the intention to devote an entire volume to this state. In planning the work as recommended in this letter, Mrs. Victor ascertained that these chapters were out of proportion for the volume as now planned, and wrote to Mr. Bancroft to this effect. On September 21st, however, he advised her that he recognized the fact, but that they would "have to do." On the same date he forwarded the dictations of three of the first Mormons in Nevada, requesting that when the material had been used for this volume, they be turned over to Mr. Bates, then at work on the History of Utah. He also suggested a perusal of Benton's City Saints and other Utah books for light on Nevada, and directed that Mr. Newkirk search the library thoroughly for Nevada material.
