TO YELLOWSTONE NATIONAL PARK. 37 
the Mammoth Springs, the bridge, the falls, the lake, and the geyser basins, for the accommoda- 
tion of visitors; and these, after the construction by the engineer officer, should be under the 
charge of an officer detailed to make constant inspections of them and of the detachments doing 
guard and police duty in the park. Visitors should be forbidden to kill any game. The hunters 
should have their arms and spoils confiscated, besides being liable to prosecution. 
For the accomplishment of these purposes, it would certainly be most convenient and expedient 
to take advantage of the presence and organization of the military, and to intrust the care of the 
park, at least temporarily, to the War Department; at least until such time as a civilian superin- 
tendent, living in the park, with a body of mounted police under his orders, should suffice for its 
protection. 
The day will come, and it cannot be far distant, when this most interesting region, crowded with 
marvels and adorned with the most superb scenery, will be rendered accessible to all; and then, 
thronged with visitors from all over the world, it will be what nature and Congress, for once work- 
ing together in unison, have declared it should be, a National Park. 
Respectfully submitted.
