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. Questions have arisen between the two Governments as to the right of New Granada to levy a tonnage duty upon the vessels of the United States in its ports of the Isthmus and to levy a passenger tax upon our citizens arriving in that country, whether with a design to remain there or to pass from ocean to ocean by the transit route; and also a tax upon the mail of the United States transported over the Panama Railroad. The Government of New Granada has been informed that the United States would consider the collection of either of these taxes as an act in violation of the treaty between the two countries, and as such would be resisted by the United States. At the same time, we are prepared to discuss these questions in a spirit of amity and justice and with a sincere desire to adjust them in a satisfactory manner. A negotiation for that purpose has already been commenced. No effort has recently been made to collect these taxes nor is any anticipated under present circumstances. With the Empire of Brazil our relations are of the most friendly character. The productions of the two countries, and especially those of an agricultural nature, are such as to invite extensive mutual exchanges. A large quantity of American flour is consumed in Brazil, whilst more than treble the amount in value of Brazilian coffee is consumed in the United States. Whilst this is the case, a heavy duty has been levied until very recently upon the importation of American flour into Brazil. I am gratified, however, to be able to inform you that in September last this has been reduced from $1.32 to about 49 cents per barrel, and the duties on other articles of our production have been diminished in nearly the same proportion.
