Yet the Mexicans not only held that the United States caused the miscarriage in order to prosecute designs upon Texas, but charged officially as well as on the street, with neither evidence nor plausibility in favor of the accusation, that our minister stole the paper--entrusted to him on May 10 for transmission--which would have authorized Obregón to exchange the ratifications. So we had in 1830 this extraordinary picture: on the one hand, the United States earnestly desiring the prosperity and friendship of Mexico, and pursuing a just and sympathetic policy towards her; and, on the other, Mexico accusing us of hostile intentions and the basest arts. From that day on, everything we did was viewed with a jaundiced eye.[3.6] The treaty of limits was, however, revived by fresh negotiations, and in April, 1832, went into effect. By its terms a joint commission to run the line had to be appointed within a year from this date, and presently Mexico received notice, both at her own capital and at ours, that an American commissioner had been named; but she paid no attention to the matter, and the year expired. Our minister was then directed to negotiate a new agreement, labored for more than twelve months, and finally, by addressing strong language personally to the acting President, carried the point. Yet the United States was officially denounced for endeavoring--and by wretched artifices--to delay the fixing of the boundary.[3.7] Meanwhile a treaty of amity and commerce, proposed by Poinsett at about the same time as the treaty of limits, had been pursuing a checkered career, though a similar agreement between Mexico and England went rapidly through. At one stage of the proceedings the Mexican plenipotentiaries kept our minister entirely in the dark about an important concession made to Great Britain, falsely assuring him that equally favorable terms were offered to this country. Indeed, Victoria showed a strong disposition to block the business altogether. July 10, 1826, however, the negotiators reached an agreement, but it did not prove satisfactory to the American Senate. A second treaty signed in February, 1828, did not please the Congress of Mexico, and was properly rejected. At a later date negotiations were again resumed; but in 1831 that body held the matter in abeyance for more than nine months. At last, one day before the session was to close, our minister gave notice that unless the treaty were concluded, he would leave the country. The government at Washington also exerted some pressure by insisting that the two matters should fare alike, and postponing the re-ratification of the treaty of limits; and consequently both treaties became law at the same time, April 5, 1832. Yet for nearly a year the commercial treaty was not promulgated by Mexico; and hence, though her citizens residing in the United States could have the benefit of it, Americans in Mexico could not, for the local authorities with whom it was necessary to deal
