principal points of interest. This accomplished, there can be no 
doubt of the speedy introduction of better methods of transport 
from without. The enterprising citizens of Montana and Wy- 
oming, encouraged by General Ord, have already agitated the sub- 
ject of an extended system of national highways through the 
Territories, and vigorous measures have been adopted to secure 
their object. This would add greatly to the facilities in this direc- : 
tion, for as I have shown, any direct route between ‘the Montana Ng 
settlements and the south or east must pass through this reser- 
vation or very near to it. But the project of a railroad through 
that section is not in its infancy, nor can it long be delayed. It 
is unnecessary to dwell upon these points, for it is obvi ious, from 
what has been said, that the attention of capitalists must soon be 
turned toward this field. I will therefore proceed to show in what 
ways I consider that the interests of science can be best furthered. | -
