By the 22d of April many of the preliminary arrangements had been completed and some of the difficulties anticipated had been smoothed over. Nearly 100 Apache scouts joined the command from the San Carlos Reservation, and in the first hours of night began a war-dance, which continued without a break until the first flush of dawn the next day. They were all in high feather, and entered into the spirit of the occasion with full zest. Not much time need be wasted upon a description of their dresses; they didn’t wear any, except breech-clout and moccasins. To the music of an improvised drum and the accompaniment of marrow-freezing yells and shrieks they pirouetted and charged in all directions, swaying their bodies violently, dropping on one knee, then suddenly springing high in air, discharging their pieces, and all the time chanting a rude refrain, in which their own prowess was exalted and that of their enemies alluded to with contempt. Their enthusiasm was not abated by the announcement, quietly diffused, that the “medicine men” had been hard at work, and had succeeded in making a “medicine” which would surely bring the Chiricahuas to grief. In accordance with the agreement entered into with the Mexican authorities, the American troops were to reach the boundary line _not sooner than May 1_, the object being to let the restless Chiricahuas quiet down as much as possible, and relax their vigilance, while at the same time it enabled the Mexican troops to get into position for effective co-operation. The convention between our government and that of Mexico, by which a reciprocal crossing of the International Boundary was conceded to the troops of the two republics, stipulated that such crossing should be authorized when the troops were “in close pursuit of a band of savage Indians,” and the crossing was made “in the unpopulated or desert parts of said boundary line,” which unpopulated or desert parts “had to be two leagues from any encampment or town of either country.” The commander of the troops crossing was to give notice at time of crossing, or before if possible, to the nearest military commander or civil authority of the country entered. The pursuing force was to retire to its own territory as soon as it should have fought the band of which it was in pursuit, or lost the trail; and in no case could it “establish itself or remain in the foreign territory for a longer time than necessary to make the pursuit of the band whose trail it had followed.”
