24 TRANSACTIONS OF THE 
“Water Ponies” might have seemed, all would have gone 
well had not “Pete” in his talk convinced the Indians 
that the white men were telling lies and that they were 
bad men and had come from Colorado to steal their 
squaws. After giving the men food and water and bid- 
ding them sleep, under the direction of “Pete”? an ambush 
was planned and shortly after starting for St. George the 
next morning, they were cruelly ambushed and killed, 
their poor bodies being literally filled with arrows. A 
watch and some other keepsakes of the men were recov- 
ered and sent back to their parents in New England and 
so closed that chapter of mistakes and sorrow. While 
waiting for the Shevwitz Indians to come from their vil- 
lage, our party made a trip down the Lateral Canyon to 
the Colorado River, looking out a point in the canyon 
where supplies might be brought in for a second expe- 
dition, the plans for which were being formulated in Pow- 
ell’s mind. Our work having been accomplished, we 
returned to Bloomington and during the fall and winter, 
I was engaged in making a map of the Green and Colo- 
rado River Canyons, from the field notes taken. This 
map when finished was the first map ever made of this 
great gorge from topographical notes, and was taken to 
Washington and placed on file in the War Department, as 
the official map of this survey of the river; and in subse- 
quent work was found to be remarkably correct. Pow- 
ell’s thirst for knowledge of this hitherto unknown coun- 
try was not quenched by the first trip, and realizing the 
many natural imperfections and defects, he immediately 
began organizing his second expedition to make a more 
perfect exploration and scientific survey of this wonder- 
land, whose mythological barriers had been burned away 
or broken, by his first canyon trip. 
In May, 1871, the second party fully equipped with 
instruments and supplies made its start from Green River, 
Wyo., with three boats and eleven men. At Brown’s 
Park, 75 miles down the river, one of the party, Mr. Rich- 
ardson, was sent back, and the other ten going on and 
making a successful exploration of the Green and Colo- 
rado Rivers and the lateral canyons as far as the head of 
Grand Canyon, at the mouth of the Pariah River, where, 
owing to the lateness of the season and the cold water,
