ARTICLE XI

Considering that a great part of the territories, which, by the present treaty, are to be comprehended for the future within the limits of the United States, is now occupied by savage tribes, who will hereafter be under the exclusive controul of the Government of the United States, and whose incursions within the territory of Mexico would be prejudicial in the extreme, it is solemnly agreed that all such incursions shall be forcibly restrained by the Government of the United States whensoever this may be necessary; and that when they cannot be prevented, they shall be punished by the said Government, and satisfaction for the same shall be exacted-all in the same way, and with equal diligence and energy, as if the same incursions were meditated or committed within its own territory, against its own citizens.

It shall not be lawful, under any pretext whatever, for any inhabitant of the United States to purchase or acquire any Mexican, or any foreigner residing in Mexico, who may have been captured by Indians inhabiting the territory of either of the two republics; nor to purchase or acquire horses, mules, cattle, or property of any kind, stolen within Mexican territory by such Indians.

And in the event of any person or persons, captured within Mexican territory by Indians, being carried into the territory of the United States, the Government of the latter engages and binds itself, in the most solemn manner, so soon as it shall know of such captives being within its territory, and shall be able so to do, through the faithful exercise of its influence and power, to rescue them and return them to their country, or deliver them to the agent or representative of the Mexican Government. The Mexican authorities will, as far as practicable, give to the Government of the United

States notice of such captures; and its agents shall pay the expenses incurred in the maintenance and transmission of the rescued captives; who, in the mean time, shall be treated with the utmost hospitality by the American authorities at the place where they may be. But if the Government of the United States, before receiving such notice from Mexico, should obtain intelligence, through any other channel, of the existence of Mexican captives within its territory, it will proceed forthwith to effect their release and delivery to the Mexican agent, as above stipulated.

For the purpose of giving to these stipulations the fullest possible efficacy, thereby affording the security and redress demanded by their true spirit and intent, the Government of the United States will now and hereafter pass, without unnecessary delay, and always vigilantly enforce, such laws as the nature of the subject may require. And, finally, the sacredness of this obligation shall never be lost sight of by the said Government, when providing for the removal of the Indians from any portion of the said territories, or for its being settled by citizens of the United States; but, on the contrary, special care shall then be taken not to place its Indian occupants under the necessity of seeking new homes, by committing those invasions which the United States have solemnly obliged themselves to restrain.

ARTICLE XII

In consideration of the extension acquired by the boundaries of the United States, as defined in the fifth article of the present treaty, the Government of the United States engages to pay to that of the Mexican Republic the sum of fifteen millions of dollars.

Immediately after this treaty shall have been duly ratified by the Government of the Mexican Republic, the sum of

three millions of dollars shall be paid to the said Government by that of the United States, at the city of Mexico, in the gold or silver coin of Mexico. The remaining twelve millions of dollars shall be paid at the same place, and in the same coin, in annual instalments of three millions of dollars each, together with interest on the same at the rate of six per centum per annum. This interest shall begin to run upon the whole sum of twelve millions from the day of the ratification of the present treaty by the Mexican Government, and the first of the instalments shall be paid at the expiration of one year from the same day. Together with each annual instalment, as it falls due, the whole interest accruing on such instalment from the beginning shall also be paid.

ARTICLE XIII

The United States engage, moreover, to assume and pay to the claimants all the amounts now due them, and those hereafter to become due, by reason of the claims already liquidated and decided against the Mexican Republic, under the conventions between the two republics severally concluded on the eleventh day of April, eighteen hundred and thirty-nine, and on the thirtieth day of January, eighteen hundred and forty-three; so that the Mexican Republic shall be absolutely exempt, for the future, from all expense whatever on account of the said claims.

ARTICLE XIV

The United States do furthermore discharge the Mexican Republic from all claims of citizens of the United States, not heretofore decided against the Mexican Government, which may have arisen previously to the date of the signature of this treaty; which discharge shall be final and per

petual, whether the said claims be rejected or be allowed by the board of commissioners provided for in the following article, and whatever shall be the total amount of those allowed.

ARTICLE XV

The United States, exonerating Mexico from all demands on account of the claims of their citizens mentioned in the preceding article, and considering them entirely and forever cancelled, whatever their amount may be, undertake to make satisfaction for the same, to an amount not exceeding three and one-quarter millions of dollars. To ascertain the validity and amount of those claims, a board of commissioners shall be established by the Government of the United States, whose awards shall be final and conclusive; provided that, in deciding upon the validity of each claim, the board shall be guided and governed by the principles and rules of decision prescribed by the first and fifth articles of the unratified convention, concluded at the city of Mexico on the twentieth day of November, one thousand eight hundred and forty-three; and in no case shall an award be made in favour of any claim not embraced by these principles and rules.

If, in the opinion of the said board of commissioners or of the claimants, any books, records, or documents, in the possession or power of the Government of the Mexican Republic, shall be deemed necessary to the just decision of any claim, the commissioners, or the claimants through them, shall, within such period as Congress may designate, make an application in writing for the same, addressed to the Mexican Minister of Foreign Affairs, to be transmitted by the Secretary of State of the United States; and the Mexican Government engages, at the earliest possible moment after the receipt of such demand, to cause any

of the books, records, or documents so specified, which shall be in their possession or power (or authenticated copies or extracts of the same), to be transmitted to the said Secretary of State, who shall immediately deliver them over to the said board of commissioners; provided that no such application shall be made by or at the instance of any claimant, until the facts which it is expected to prove by such books, records, or documents, shall have been stated under oath or affirmation.

ARTICLE XVI

Each of the contracting parties reserves to itself the entire right to fortify whatever point within its territory it may judge proper so to fortify for its security.

ARTICLE XVII

The treaty of amity, commerce, and navigation, concluded at the city of Mexico on the fifth day of April, A. D. 1831, between the United States of America and the United Mexican States, except the additional article, and except so far as the stipulations of the said treaty may be incompatible with any stipulation contained in the present treaty, is hereby revived for the period of eight years from the day of the exchange of ratifications of this treaty, with the same force and virtue as if incorporated therein; it being understood that each of the contracting parties reserves to itself the right, at any time after the said period of eight years shall have expired, to terminate the same by giving one year's notice of such intention to the other party.

ARTICLE XVIII

All supplies whatever for troops of the United States in Mexico, arriving at ports in the occupation of such
