States of Europe consent to this arrangement (and we have no reason to suppose that a proposition so fair and honorable will be opposed by any), the energies of their people and ours will cooperate in promoting the success of the enterprise.  I do not recommend any appropriation from the National Treasury for this purpose, nor do I believe that such an appropriation is necessary.  Private enterprise, if properly protected, will complete the work should it prove to be feasible.  The parties who have procured the charter from Nicaragua for its construction desire no assistance from this Government beyond its protection; and they profess that, having examined the proposed line of communication, they will be ready to commence the undertaking whenever that protection shall be extended to them.  Should there appear to be reason, on examining the whole evidence, to entertain a serious doubt of the practicability of constructing such a canal, that doubt could be speedily solved by an actual exploration of the route.

Should such a work be constructed under the common protection of all nations, for equal benefits to all, it would be neither just nor expedient that any great maritime state should command the communication.  The territory through which the canal may be opened ought to be freed from the claims of any foreign power.  No such power should occupy a position that would enable it hereafter to exercise so controlling an influence over the commerce of the world or to obstruct a highway which ought to be dedicated to the common uses of mankind.

The routes across the Isthmus at Tehuantepec and Panama are also worthy of our serious consideration.  They did not fail to engage the attention of my predecessor.  The negotiator of the treaty of Guadalupe Hidalgo was instructed to offer a very large sum of money for the right of transit across the Isthmus of Tehuantepec.  The Mexican Government did not accede to the proposition for the purchase of the right of way, probably because it had already contracted with private individuals for the construction of a passage from the Guasacualco River to Tehuantepec.  I shall not renew any proposition to purchase for money a right which ought to be 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.
