ters and irrigable lands of the Arid Region. It is hard to
say which of these is greater or which was nearer his heart. Together
they constitute a far-reaching influence in the development of the
country such as no one man heretofore has contributed. His Studies and
recommendations with regard to the arid lands of the West are of the
greatest importance to that district and to the country at large and the
nearer they can be carried out the better will it be for posterity. He
perceived at once that the reservation of sites for storage reservoirs
was of the first importance and this was one of the earliest steps he
endeavoured to bring about.

Of late years when he might have relaxed his labours, he turned his
attention to the field of psychology and philosophy, working till his
malady, sclerosis of the arteries, produced his last illness. The result
was two treatises in this line. Truth and Error, published in 1899,
and "treating of matter, motion, and consciousness as related to the
external universe or the field of fact," as Gilbert describes it,
and Good and Evil, running as a series of essays in the American
Anthropologist, treating of the same factors as related to humanity or
to welfare. A third volume was planned to deal with the emotions, and he
had also woven these ideas into a series of poems, of which only one
has been published. Few understand these later products of Powell. Many
condemn them; but Gilbert expresses his usual clear, unbiassed view
of things and says (and I can do no better than to quote him, a man of
remarkably direct thought, and for many years very close to Powell):
"His philosophic writings belong to a field in which thought has ever
found language inadequate, and are for the present, so far as may be
judged from the reviews of Truth and Error, largely misunderstood.
Admitting myself to be of those who fail to understand much of his
philosophy, I do not therefore condemn it as worthless, for in other
fields of his thought events have proved that he was not visionary, but
merely in advance of his time."

One inexplicable action in his career, to my mind, was his complete
ignoring in his report of the men and their work, of his second river
expedition, particularly of his colleague, Prof. Thompson, whose skill
and energy were so largely responsible for the scientific and practical
success of the second expedition. The report embodied all the results
achieved by this expedition and gave no cr
