Where gold or silver in any form is taken from any interior Mexican city
in our military possession, the export duty must be paid there to the
officer of the United States commanding, and his certificate of such
prepayment must be produced at the Mexican port of exportation;
otherwise a double duty will be collected upon the arrival of such gold
or silver at the Mexican port of exportation. Whenever it is
practicable, all internal taxes of every description, whether upon
persons or property, exacted by the Government of Mexico, or by any
department, town, or city thereof, should be collected by our military
officers in possession and appropriated as a military contribution
toward defraying the expenses of the war, excluding however, all duties
on the transit of goods from one department to another, which duties,
being prejudicial to revenue and restrictive of the exchange of imports
for exports, were abolished by your order of the 31st of March last.

Yours, most respectfully,

R.J. WALKER
_Secretary of the Treasury_.
