edit to the men who with
unflagging zeal, under stress and difficulties innumerable accumulated
the data. This has ever appeared to me unjust, but his reasons for it
were doubtless satisfactory to himself. The second expedition is put on
record, for the first time in this volume, except for a lecture of mine
printed some years ago in the Bulletin of the American Geographical
Society.

The life of Powell is an example of the triumph of intelligent,
persistent endeavour. Long ago he had formulated many of his plans and
as far back as 1877, and even 1871, as I understood them, he carried
them out with remarkable precision. Before the authorisation of the
Bureau of Ethnology, its scope was developed in his mind and he saw
completed the many volumes which have since been published. His power to
observe the field ahead, standing on the imperfections of the present,
was extraordinary. As a soldier he was a patriot, as an explorer he was
a hero. As a far-seeing scientific man, as an organiser of government
scientific work, as a loving, friendly, and a delightful comrade whether
by the camp-fire or in the study, and as a true sympathiser with the
aspirations and ambitions of subordinates or equals, there has seldom
been his superior.
