One week after this decree went forth, another prohibited the importation of certain specified articles at any point, and ordered the forfeiture of such merchandise, already in the hands of dealers, if not sold within the ensuing twelve months. The list of articles, printed solidly in small type, filled nearly an octavo page, and apparently was intended to include almost everything embraced in our trade with Mexico. Peculiarly harsh seemed the forfeiture provision. Not only was it _ex post facto_, but our traders by paying the duty had become entitled to the privilege of selling their goods; and the American secretary of state could do no less than protest against the law, as "a manifest violation of the liberty of trade secured by the treaty." Yet something still more serious followed it, for aliens were soon prohibited from doing retail business at all. An attempt was made to defend this order on the ground that Americans residing in the country were subject to its laws, usages and statutes; but our government replied that a treaty must be regarded as the supreme law, and that if one solemn agreement with Mexico could thus be made a nullity, all the other privileges accorded us could one by one be abrogated.[3.21] These commercial grievances, however, were trifles compared with another of the same halcyon period. In July, 1843, Tornel, the minister of war, instructed the governors of California and three other northern departments to expel all citizens of the United States residing therein, and permit no more of them to enter. Extraordinary precautions were taken to keep this measure secret, and Waddy Thompson, our representative at Mexico, first learned of it on December 23. Four times he inquired in vain whether such an order had been issued; but when he demanded his passports, Bocanegra attempted to justify Tornel's instructions, arguing that every government is authorized to protect itself against seditious aliens. This was an evasion, for the order had reference to all Americans, however law-abiding. The outcome was that now, after the order had been in force almost six months and after it had been executed in at least one department, directions were given to make it include all foreigners, and apply only to the seditious. Thompson, strongly disposed to please the Mexicans, accepted this as satisfactory; but his country did not, for the governors had authority still to decide what Americans were dangerous, and expel these without a trial. Besides, even the modified order required them to prevent our citizens from entering their jurisdictions, and thus plainly violated the treaty.[3.22]
