subsequently to the restoration of the custom-houses, and previously to the sixty days fixed in the following article
for the coming into force of the Mexican tariff at such ports respectively; the said merchandise, effects, and property
being however, at the time of their importation, subject to the payment of duties, as provided for in the said following
article.
3. All merchandise, effects, and property described in the two rules foregoing shall, during their continuance at the place of importation, and upon their leaving such plaeo for the interior, be exempt from all duty, tax, or impost of every kind, under whatsoever title or denomination. Nor shall they be there subjected to any charge whatsoever upon the sale thereof.
4. All merchandise, effects, and property, described in the first and second rules, which shall have been removed to any place in the interior whilst such place was in the occupation of the forces of the United States, shall, during their continuance therein, be exempt from all tax upon the sale or consumption thereof, and from every kind of impost or contribution, under whatsoever title or denomination.
5. But if any merchandise, effects, or property, described in the first and second rules, shall be removed to any place not occupied at the time by the forces of the United States, they shall, upon their introduction into such place, or upon their sale or consumption there, be subject to the same duties which, under the Mexican laws, they would be required to pay in such cases if they had been imported in time of peace, through the maritime custom-houses, and had there paid the duties conformably with the Mexican tariff.
6. The owners of all merchandise, effects, or property described in the first and second rules, and existing in any port of Mexico, shall have the right to re-ship the same, exempt from all tax, impost, or contribution whatever.
With respect to the metals, or other property, exported from any Mexican port whilst in the occupation of the forces of the United States, and previously to the restoration of the custom-house at such port, no person shall be required by the Mexican authorities, whether general or state, to pay any tax, duty, or contribution upon any such exportation, or in any manner to account for the same to the said authorities.
ARTICLE XX.
Through consideration for the interests of commerce generally, it is agreed, that if less than sixty days should elapse between the date of the signature of this treaty and the restoration of tho custom-houses conformably with the stipulation in the third article, in such case all merchandise, effects, and property whatsoever, arriving at the Mexican ports after the restoration of the said custom-houses, and previously to the expiration of sixty days after the day of the signature of this treaty, shall be admitted to entry; and no other duties shall be levied thereon than the duties established by the tariff found in force at such custom-houses at the time of the restoration of the same. And to all such merchandise, effects, and property, the rules established by the preceding article shall apply.
ARTICLE XXI.
If unhappily any disagreement should hereafter arise between the governments of the two republics, whether with respect to the interpretation of any stipulation in this treaty, or with respect to any other particular concerning the political or commercial relations of the two nations, the said governments, in the name of those nations; do promise to each other that they will endeavor, in the most sincere and earnest manner, to settle the differences so arising, and to preserve the state of peace and friendship in which the two countries are now placing themselves; using, for this end, mutual representations and pacific negotiations. And if, by these means, they should not be enabled to come to an agreement, a resort shall not, on this account, be had to reprisals, aggression, or hostility of any kind, by the one republic against the other, until the government of that which deems itself aggrieved shall have maturely considered, in the spirit of peace and good neighborship, whether it would not be better that such difference should be settled by the arbitration of commissioners appointed on each side, or by that of a friendly nation. And should such course be proposed by either party, it shall be acceded to by the other, unless deemed by it altogether incompatible with the nature of the difference, or the circumstances of the case.
ARTICLE XXII.
If (which is not to be expected, and which God forbid!) war should unhappily break out between the two republics,
