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:
