ed to the claimants, was a
liquidated and ascertained debt due by Mexico, about which there could
be no dispute, and which she was bound to pay according to the terms of
the convention. Soon after the final awards for this amount had been
made the Mexican Government asked for a postponement of the time of
making payment, alleging that it would be inconvenient to make the
payment at the time stipulated. In the spirit of forbearing kindness
toward a sister republic, which Mexico has so long abused, the United
States promptly complied with her request. A second convention was
accordingly concluded between the two Governments on the 30th of
January, 1843, which upon its face declares that "this new arrangement
is entered into for the accommodation of Mexico." By the terms of this
convention all the interest due on the awards which had been made in
favor of the claimants under the convention of the 11th of April, 1839,
was to be paid to them on the 30th of April, 1843, and "the principal of
the said awards and the interest accruing thereon" was stipulated to
"be paid in five years, in equal installments every three months."
Notwithstanding this new convention was entered into at the request of
Mexico and for the purpose of relieving her from embarrassment, the
claimants have only received the interest due on the 30th of April,
1843, and three of the twenty installments. Although the payment of the
sum thus liquidated and confessedly due by Mexico to our citizens as
indemnity for acknowledged acts of outrage and wrong was secured by
treaty, the obligations of which are ever held sacred by all just
nations, yet Mexico has violated this solemn engagement by failing and
refusing to make the payment. The two installments due in April and
July, 1844, under the peculiar circumstances connected with them, have
been assumed by the United States and discharged to the claimants, but
they are still due by Mexico. But this is not all of which we have just
cause of complaint. To provide a remedy for the claimants whose cases
were not decided by the joint commission under the convention of April
11, 1839, it was expressly stipulated by the sixth article of the
convention of the 30th of January, 1843, that--

A new convention shall be entered into for the settlement of all claims
of the Government and citizens of the United States against the Republic
of Mexico which were not finally decided by the late commission which
met in the c
