2nd. That a line of Posts be established along the traveled route to Oregon, at a distance, so far as practicable, of not more than 50 miles. That these Posts be located so as to afford the best opportunity for agriculture and grazing, to facilitate the production of provisions, and the care of horses and cattle, for the use and support of said Posts, and to furnish supplies to all passers through Indian territory, especially to mail-carriers and troops.
These Posts should be placed wherever a bridge or ferry would be required to facilitate the transport of the mail, and travel of troops or immigrants through the country.
In all fertile places, these Posts would support themselves, and give facilities for the several objects just named in transit. The other Posts, situated where the soil would not admit of cultivation, would still be useful, as they would afford the means of taking care of horses, and other facilities of transporting the mails.
These Posts could be supplied with provisions from others in the vicinity. A few large Posts in the more fertile regions could supply those more in the mountains.
On the other hand, military Posts can only be well supplied when near the settlements. In this way all transports for the supply of interior military Posts would be superseded. 334
The number of men at these Posts might vary from five to twenty-five.
