equally secured to all nations on payment of a reasonable
toll to the owners of the improvement, who would doubtless be well
contented with that compensation and the guaranties of the maritime
states of the world in separate treaties negotiated with Mexico, binding
her and them to protect those who should construct the work. Such
guaranties would do more to secure the completion of the communication
through the territory of Mexico than any other reasonable consideration
that could be offered; and as Mexico herself would be the greatest
gainer by the opening of this communication between the Gulf and the
Pacific Ocean, it is presumed that she would not hesitate to yield her
aid in the manner proposed to accomplish an improvement so important to
her own best interests.

We have reason to hope that the proposed railroad across the Isthmus at
Panama will be successfully constructed under the protection of the late
treaty with New Granada, ratified and exchanged by my predecessor on the
10th day of June, 1848, which guarantees the perfect neutrality of the
Isthmus and the rights of sovereignty and property of New Granada over
that territory, "with a view that the free transit from ocean to ocean
may not be interrupted or embarrassed" during the existence of the
treaty. It is our policy to encourage every practicable route across the
isthmus which connects North and South America, either by railroad or
canal, which the energy and enterprise of our citizens may induce them
to complete, and I consider it obligatory upon me to adopt that policy,
especially in consequence of the absolute necessity of facilitating
intercourse with our possessions on the Pacific.

The position of the Sandwich Islands with reference to the territory of
the United States on the Pacific, the success of our persevering and
benevolent citizens who have repaired to that remote quarter in
Christianizing the natives and inducing them to adopt a system of
government and laws suited to their capacity and wants, and the use made
by our numerous whale ships of the harbors of the islands as places of
resort for obtaining refreshments and repairs all combine to render
their destiny peculiarly interesting to us. It is our duty to encourage
the authorities of those islands in their efforts to improve and elevate
the moral and political condition of the inhabitants, and we should make
reasonable allowances for the difficulties inseparable from this task.
We desire
