States, as well as by several European nations.--The disturbances in Mexico are deplored:--steps have been taken to prevent American citizens from aiding the rebellion in the northern departments. A convention has been entered into between Mexico and the United States, intended to impart a feeling of security to those citizens of the United States who have undertaken to construct a railroad across the Isthmus of Tehuantepec;--it has not yet, however, been ratified by the Congress and Executive of that country. The only object which our government has had in view, has been the construction of a passage from ocean to ocean, the shortest and best for travelers and merchandise, and equally open to all the world. It has sought neither territorial acquisition, nor any advantages peculiar to itself. It will therefore continue to exert all proper efforts to secure the co-operation of Mexico.--The republic of Nicaragua has been so much disturbed by internal convulsions, that nothing can be done as yet toward disposing of the questions pending between the two countries.--Inter-oceanic communication from the mouth of the St. John to the Pacific has been so far accomplished that passengers and merchandise have been transported over it. A considerable part of the railroad across the isthmus has been completed. Peace has been concluded between the contending parties in the island of St. Domingo. The office of Commissioner to China is not yet filled:--a higher salary is asked for it. The aggregate receipts of the last fiscal year amounted to $52,312,979:--the total expenditures $48,005,878. The total imports of the year were $215,725,995, of which $4,967,901 was in specie. The total exports were $217,517,130, of which $29,231,880 was in specie. Since the 1st of December 1850, the payments on account of the principal of the public debt have amounted to $7,501,456, which includes $3,242,400 paid to Mexico and $2,591,253 awarded to American citizens under the Mexican treaty. The public debt on the 20th of November, exclusive of stock authorized to be issued to Texas, was $62,560,395. The receipts for the next fiscal year are estimated at $51,800,000. The total expenditures for the next year are estimated at $42,892,299, of which $33,343,198 will be needed for the ordinary expenses of the government, and $9,549,101 for payments of the public debt and expenses consequent on our territorial acquisitions. The value of our exports is $43,648,322 more than it was the year before last, but this is owing mainly to the increased price of cotton. The value of our exports of bread stuffs and provisions has fallen from $68,701,921 in 1847, to $26,051,373 in 1850, and to $21,948,653 in 1851, with a strong probability of a still farther reduction in the current year. In the exports of rice and tobacco there has also been a large decrease. These facts are cited as showing the fallacy of expecting increased exports from a reduced tariff. The
