steamer at our disposal. Mr. Harwood accompanied us on all of our trips about this 
region and assisted us in many ways. I was able to make much more thorough inves- 
tigations in the vicinity of Bozeman than would otherwise have been possible in the 
time at my disposal, through the kind and courteous assistance of Hon. O. P. Chisholm, 
Walter Cooper, esq., and Mr. W. A. Imes. To Capt. George S. Anderson, U. S. Army, 
acting superintendent of the Yellowstone National Park, we are under special obliga- 
tions for the loan of blankets and other articles, which added greatly to the comfort of 
our trip through the Park. Capt. Anderson takes an active and intelligent interest in 
the efforts of the Commission to stock the Park with valuable food-fishes, and is ever 
ready to assist it in all proper ways. The opportunity to make the trip from Canon 
Hotel to Horsethief Springs was due to the kindness of Mr. B. B. Cummins, who fur- 
nished free conveyance to the springs and back again to Mammoth Hot Springs.
