By the time this work was completed the loose antelope had been caught and the wounded strapped to their backs. At a word from their commander the party formed with military precision, a detail started ahead with the wounded and a moment later the balance of the troop was mounted and on the way. The method of mounting and taking up the march was unique and a source of considerable interest to Tarzan. The dismounted warriors were standing in line facing the young leader who was mounted, as were the several officers who accompanied him. Each warrior held his mount by the bridle. The commander made a rapid signal with the raised point of his sword--there was no spoken word of command--immediately after which he dropped the point quickly at his side simultaneously wheeling his mount, which leaped quickly off in the direction that the troop was facing, the mounts of his officers wheeling with him as though actuated by a single brain, and at the same instant the mount of each alternate warrior in the line leaped forward and as it leaped its rider swung to his saddle, vaulting to his seat as lightly as a feather. The instant the first line had cleared them the antelopes of the second line leaped in pursuit, their riders mounted as had the others before them and with a second and longer leap the intervals were closed and the whole troop raced forward in a compact line. It was a most clever and practical evolution and one that made it possible to put mounted troops in motion as rapidly as foot troops; there was no long delay caused by taking distance, mounting and closing ranks. As the troop galloped away ten warriors wheeled from the left flank and, following one of the officers who had detached himself from the party of the commander of the troop, returned to Tarzan. By signs the officer conveyed to the ape-man the intelligence that he was to follow this party which would guide him to their destination. Already the main body was far away across the open plain, their lithe mounts clearing as many as five or six feet in a single bound. Even the swift Tarzan could not have kept pace with them. As the ape-man started away under the guidance of the detachment his thoughts reverted for an instant to the Alalus youth who was hunting alone in the forest behind them, but he soon put the creature from his mind with the realization that it was better equipped to defend itself than any of its kind, and that when he had made his visit to the country of the pygmies he could doubtless return and find the Alalus, if he so desired.
