US Presidency

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.
