account of it, but only of recording the scientific results. Immediately
on my return I was interviewed a number of times, and these interviews
were published in the daily press; and here I supposed all interest in
the exploration ended. But in 1874 the editors of Scribner's Monthly
requested me to publish a popular account of the Colorado exploration in
that journal. To this I acceded and prepared four short articles, which
were elaborately illustrated from photographs in my possession.

In the same year--1874--at the instance of Professor Henry of the
Smithsonian Institution, I was called before an appropriations committee
of the House of Representatives to explain certain estimates made by the
Professor for funds to continue scientific work which had been in
progress from the date of the original exploration. Mr. Garfield was
chairman of the committee, and after listening to my account of the
progress of the geographic and geologic work, he asked me why no history
of the original exploration of the canyons had been published. I
informed him that I had no interest in that work as an adventure, but
was interested only in the scientific results, and that these results
had in part been published and in part were in course of publication.
Thereupon Mr. Garfield, in a pleasant manner, insisted that the history
of the exploration should be published by the government, and that I
must understand that my scientific work would be continued by additional
appropriations only upon my promise that I would publish an account of
the exploration. I made the promise, and the task was immediately
undertaken.

My daily journal had been kept on long and narrow strips of brown paper,
which were gathered into little volumes that were bound in sole leather
in camp as they were completed. After some deliberation I decided to
publish this journal, with only such emendations and corrections as its
