[1] I use the title Major for the reason that he was so widely known for so long a period by it. He was a volunteer officer during the Civil War, holding the rank of Colonel at the end. The title Major, then, has no military significance in this connection. When his report to Congress was published, Major Powell, perhaps for the sake of dramatic unity, concluded to omit mention of the personnel of the second expedition, awarding credit, for all that was accomplished, to the men of his first wonderful voyage of 1869. And these men surely deserved all that could be bestowed on them. They had, under the Major’s clear-sighted guidance and cool judgment, performed one of the distinguished feats of history. They had faced unknown dangers. They had determined that the forbidding torrent could be mastered. But it has always seemed to me that the men of the second party, who made the same journey, who mapped and explored the river and much of the country roundabout, doing a large amount of difficult work in the scientific line, should have been accorded some recognition. The absence of this has sometimes been embarrassing for the reason that when statements of members of the second party were referred to the official report, their names were found missing from the list. This inclined to produce an unfavourable impression concerning these individuals. In order to provide in my own case against any unpleasant circumstance owing to this omission, I wrote to Major Powell on the subject and received the following highly satisfactory answer: Washington, D. C., January 18, 1888. My Dear Dellenbaugh: Replying to your note of the 14th instant, it gives me great pleasure to state that you were a member of my second party of exploration down the Colorado, during the years 1871 and 1872, that you occupied a place in my own boat and rendered valuable services to the expedition, and that it was with regret on my part that your connection with the Survey ceased. Yours cordially, J. W. Powell. Recently, when I informed him of my intention to publish this volume, he very kindly wrote as follows: Washington, January 6, 1902. Dear Dellenbaugh: I am pleased to hear that you are engaged in writing a book on the Colorado Canyon. I hope that you will put on record the second trip and the gentlemen who were members of that expedition. No other trip has been made since that time, though many have tried to follow us. One party, that headed by Mr. Stanton, went through the Grand Canyon on its second attempt, but many persons have lost their lives in attempting to follow us through the whole length of the canyons. I shall be very glad to write a short introduction to your book. Yours cordially, J. W. Powell.
