Following our faithful Osages, who experienced no difficulty in keeping the trail, we marched until near sundown, when we arrived at the banks of a small stream upon which, and near a cool, bubbling spring, we discovered the evidences of an Indian camp, which must have not only included the lodge whose trail we had been following, but about a dozen others. Here was a speedier confirmation of my hopes than I had anticipated. Here I determined to encamp until morning, and while the cavalry were unsaddling and pitching their tents, I asked Mo-nah-see-tah to examine the Indian camp minutely and to tell me how long a time had elapsed since its occupation by the Indians, how many constituted the party, and the character and probable indications of the latter.

No detective could have set about the proposed examination with greater thoroughness than did this Indian girl. The ashes of the camp fires were raked carefully away and examined with all the scrutiny of a chemical analysis. Bits of cloth or fragments of the skins of animals found within the limits of the camp were lifted from their resting-places as tenderly as if they were articles of greatest value. Here and there were to be seen the bones of deer or antelope which had been obtained by the Indians as food. These Mo-nah-see-tah examined carefully; then, shattering them between two stones, the condition of the marrow seemed a point of particular importance to her as tending to determine the length of time the bones had been lying on the camp. After many minutes spent in this examination, during which I accompanied her, a silent but far from disinterested spectator, she, apparently like a judge who had been carefully reviewing all the evidence, gave me her conclusions, communicating with me, through the medium of the sign language, with a grace characteristic of the Indian race, and which added to the interest of her statements.

Briefly summed up her conclusions were as follows: twelve lodges had encamped at that point, probably constituting the band of some petty chief, the different members of which, like the one whose trail we had that day discovered, had been separated for purposes of hunting, but had been called together at that point preparatory to joining the main village. The lodges had left this camp not to exceed two weeks previous to that date, and in all probability had moved to the rendezvous appointed for the main tribe, which would without doubt be found by other small bands from time to time, until the village would all be assembled at one point. Moving in this manner and at this early season of the year, when grass was scarce and no enemy known to be in the country, the Indians would make very short moves each day, passing merely from one stream to another, not accomplishing in one day a greater distance, probably, than the cavalry would in two or three hours.

This intelligence, of course, was most gratifying, and for encouragement was soon communicated to the individual members of the command. The trail was found to lead almost in a northerly direction, slightly inclining to the east. Perhaps no one of the command experienced such a feeling of hope and anxious suspense as the new discoveries gave rise to in the breast of young Brewster, who now more than ever believed, and with reason too, that he was soon to unravel or forever seal the fate of his lost sister, whose discovery and release had been the governing impulses of his life for months past.

With renewed interest the cavalry resumed the pursuit at daylight the following morning. We had marched but a few miles before we reached a second camping ground, which had been occupied not only by those whose trail we were then following, but the number of fires showed that the strength of the Indians had been increased by about twenty-five lodges, thus verifying the correctness of the surmises advanced by Mo-nah-see-tah.

Continuing our progress, we had the satisfaction of seeing still further accessions to the trail, until it was evident that at least one hundred lodges had united and passed in one body on the trail. As we marched in one day over the distance passed over in three by the Indians, and as the latter were moving unsuspicious of the presence of an enemy in that section of the country, the trail was becoming freshened as we advanced.

That night we encamped with every precaution calculated to conceal our presence from the Indians. No fires were permitted until after dark, and then but small ones, for fear the quick and watchful eye of the Indian might detect the ascending columns of smoke. As soon as the men had prepared their suppers the fires were put out. In the morning breakfast was prepared before daylight, and the fires at once smothered by heaping damp earth over them.

Resuming the pursuit as soon as it was sufficiently light to follow the trail, we soon arrived at the camp vacated by the Indians the previous day, the extent of which showed that from three to four hundred lodges of Indians had occupied the ground. In many places the decayed embers of the lodge fires were still glowing; while the immense quantity of young cottonwood timber found cut and lying throughout the camp stripped of its young bark, showed that the Indian ponies were being mainly subsisted on cottonwood bark, the spring grass not being sufficiently advanced to answer the purpose. Nothing indicated that the Indians had departed in a precipitate manner, or that they had discovered our approach. It was reasonable, therefore, to suppose that we would come in contact with them that day, if not actually reach the village.

All our plans were made accordingly. The Osages, as usual, were kept in the advance, that their quick eyes might the sooner discover the Indians should they appear in our front. In order to avail myself of the earliest information, I, with Colonel Cook, accompanied the Osages. Two of the latter kept in advance of all, and as they neared a ridge or commanding piece of ground they would cautiously approach the crest on foot and peer beyond, to ascertain whether an enemy was in sight before exposing our party to discovery. This proceeding, a customary one with Indians, did not excite unusual attention upon the part of Colonel Cook and myself, until once we saw Hard Rope, the head warrior, who was in advance, slowly ascend a slight eminence in our front, and, after casting one glimpse beyond, descend the hill and return to us as rapidly as his pony could carry him. We almost anticipated his report, so confident was everybody in the command that we were going to overtake the village.

In a few words Hard Rope informed us that less than a mile beyond the hill from which he had obtained a view, there was in plain sight a large herd of Indian ponies grazing, being herded and driven by a few Indian boys. As yet they had not seen us, but were liable to discover the column of troops further to the rear. To judge of the situation I dismounted, and, conducted by Hard Rope, advanced to the crest of the hill in front and looked beyond; there I saw in plain view the herd of ponies, numbering perhaps two hundred, and being driven in the opposite direction toward what seemed the valley of a stream, as I could see the tops of the forest trees which usually border the water courses.
