is. He went as a topographer. Hillers
was a soldier in the Civil War, and was at first not specially assigned,
but later, when the photographer gave out, he was directed to assist
in that branch, and eventually became head photographer, a position
he afterwards held with the Geological Survey for many years. A large
number of the photographs from which this volume is illustrated were
taken by him and they speak for themselves. Thompson was from Illinois.
He also had been a soldier in the war, and on this expedition was
Powell's colleague, as well as the geographer. To his foresight, rare
good judgment, ability to think out a plan to the last minute detail,
fine nerve and absolute lack, of any kind of foolishness, together
with a wide knowledge and intelligence, this expedition, and indeed the
scientific work so admirably carried on by the United States Survey of
the Rocky Mountain region and the Geological Survey for three decades in
the Far West, largely owe success. Steward was an old soldier, was from
Illinois, and went with us as geologist, assisting Powell himself in
this line. Bishop had been a captain in the war, had been shot through
and through the left lung, and was an enthusiast in Western exploration.
He was one of the topographers. Richardson was from Chicago and was
general assistant to the geologists and topographers. Beaman was from
New York. He was photographer; and W. C. Powell, from Illinois, and a
nephew of Major Powell, was his assistant. Hattan was a Virginian, but
had lived long in Illinois. He had been a soldier in the war, and went
with us as cook, because he wanted the trip, and there was no other post
open to him. I hailed from Buffalo, was the youngest of the party,
and served as artist to the geologists, and later was placed on the
topographical work. Mrs. Powell and Mrs. Thompson spent several days
at Green River and rendered much assistance, the latter presenting each
boat with a handsome flag made by her own hands.

An arm-chair obtained from Field was arranged so that it could be
strapped on the deck of the middle cabin of our boat, as a seat for
Powell, to enable him to be comfortable and at the same time see well
ahead. This had a tendency to make the Dean slightly top-heavy, but only
once did serious consequences apparently result from it, and I am not
sure that the absence of the high load would have made any difference.
Though Powell had descended before, he could not remember every
