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.

Against New Granada we have long-standing causes of complaint, arising out of the unsatisfied claims of our citizens upon that Republic, and to these have been more recently added the outrages committed upon our citizens at Panama in April, 1856.  A treaty for the adjustment of these difficulties was concluded by the Secretary of State and the minister of New Granada in September, 1857, which contained just and acceptable provisions for that purpose.  This treaty was transmitted to Bogota and was ratified by the Government of New Granada, but with certain amendments.  It was not, however, returned to this city until after the close of the last session of the Senate.  It will be immediately transmitted to that body for their advice and consent, and should this be obtained it will remove all our existing causes of complaint against New Granada on the subject of claims.
