The means made use of up to the present time would be sufficient, if applied with care. The Legislature hoped, as much as it desired, that such would be the case. Great anxiety was felt as to the nature of the measures which the government would adopt: the general expectation seemed to be that the President Arista would take the whole government into his own hands, and the suggestion was received with a good deal of favor. It was rumored that the aid of the United States had been sought for such an attempt--to be given in the shape of six millions of dollars, in return for abrogating that clause of the treaty which requires them to protect the Mexican frontier from the Indians. This, however, is mere conjecture as yet.----Serious difficulties have arisen between the Mexican authorities and the American Consul, Mr. F. W. Rice, at Acapulco. Mr. Rice sold the propeller Stockton, for wages due to her hands: she was bid off by Mr. Snyder, the chief engineer, at $3000 cash down, and $8500 within twenty-four hours after the sale. He asked and obtained two delays in making the first payment; and finally said he could not pay it until the next day. Upon this Mr. Rice again advertised the vessel for sale, on his account: she was sold to Capt. Triton, of Panama, for $4250. Mr. Snyder then applied to the Mexican court, and the judge went on board, broke the Consular seals, took possession of the vessel, and advertised her again for sale. Mr. Rice proclaimed the sale illegal, and protested against it, and, further, prevented Mr. Snyder forcibly from tearing down his posted protest. At the day of sale no bidders appeared. The Mexican authorities then arrested Mr. Rice, and committed him to prison, where he remained at the latest dates. Proper representations have of course been made to the U. S. government, and the matter will doubtless receive proper attention.----An encounter had taken place in Sonora, between a party of 300 Indians and a detachment of regular Mexican troops and National Guards. The latter were forced to retreat.----Gen. Mejia; who acquired some distinction during the late war, died recently in the city of Mexico, and Gen. Michelena, at Morelia.----The refusal of Congress to admit foreign flour, free of duty, had created a good deal of feeling in those districts where the want of it is most severely felt. In Vera Cruz, a large public meeting was held, at which it was determined to request the local authorities to send for a supply of flour, without regard to the law.----The State of Durango is in a melancholy condition: hunger, pestilence, and continued incursions of the Indians, have rendered it nearly desolate.----Four of the revolutionists under Caravajal, captured by the Mexicans, were executed by Gen. Avalos, at Matamoras, in June: two of them were Americans. SOUTH AMERICA.
