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 geo¬ 
grapher. 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.

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 assist¬ 
ance, 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 
detail and kept a sharp lookout always. The provisions—
