It is only on the borders of the respective States and Territories that any interruption will be found in the operation of these principles.

12th. Here also a modification of the same principle enacted by the several States and Territories might produce equally happy results.

13th. The mail may, with a change of horses every fifty miles, be carried at the rate of one hundred to one hundred and fifty miles in twenty-four hours.

14th. The leading reason in favor of adopting the aforesaid regulations would be, that by this means the Indians would become our faithful allies. In fact, they will be the best possible police for such a territory. This police can safely be relied upon when under a good supervision. Troops will only be required to correct their faults in cases of extreme misconduct.

15th. In closing, I would remark that I have conversed with many of the principal fur-traders of the American and Hudson Bay Companies, all of whom agree that the several regulations suggested in this communication will accomplish the object proposed, were suitable men appointed for its management and execution.

Respectfully yours,
MARCUS WHITMAN.
