In regard to the Tehuantepec route, which has been recently opened under the most favorable auspices, our treaty with Mexico of the 30th December, 1853, secures to the citizens of the United States a right of transit over it for their persons and merchandise and stipulates that neither Government shall "interpose any obstacle" thereto. It also concedes to the United States the "right to transport across the Isthmus, in closed bags, the mails of the United States not intended for distribution along the line of the communication; also the effects of the United States Government and its citizens which may be intended for transit and not for distribution on the Isthmus, free of custom-house or other charges by the Mexican Government." These treaty stipulations with New Granada and Mexico, in addition to the considerations applicable to the Nicaragua route, seem to require legislation for the purpose of carrying them into effect. The injuries which have been inflicted upon our citizens in Costa Rica and Nicaragua during the last two or three years have received the prompt attention of this Government. Some of these injuries were of the most aggravated character. The transaction at Virgin Bay in April, 1856, when a company of unarmed Americans, who were in no way connected with any belligerent conduct or party, were fired upon by the troops of Costa Rica and numbers of them killed and wounded, was brought to the knowledge of Congress by my predecessor soon after its occurrence, and was also presented to the Government of Costa Rica for that immediate investigation and redress which the nature of the case demanded. A similar course was pursued with reference to other outrages in these countries, some of which were hardly less aggravated in their character than the transaction at Virgin Bay. At the time, however, when our present minister to Nicaragua was appointed, in December, 1857, no redress had been obtained for any of these wrongs and no reply even had been received to the demands which had been made by this Government upon that of Costa Rica more than a year before. Our minister was instructed, therefore, to lose no time in expressing to those Governments the deep regret with which the President had witnessed this inattention to the just claims of the United States and in demanding their prompt and satisfactory adjustment. Unless this demand shall be complied with at an early day it will only remain for this Government to adopt such other measures as may be necessary in order to obtain for itself that justice which it has in vain attempted to secure by peaceful means from the Governments of Nicaragua and Costa Rica. While it has shown, and will continue to show, the most sincere regard for the rights and honor of these Republics, it can not permit this regard to be met by an utter neglect on their part of what is due to the Government and citizens of the United States.
