Myles remained where he was, with every indication of extreme terror, as the Cupian let down a rope ladder from the top of the wall, and descended. “Hold up your hands!” Up shot Cabot’s right hand. It was the signal agreed on with the concealed sharpshooter. _Ping!_ The sentinel dropped to the ground without a sound. _Ping!_ The light went out. Hastily the earth-man exchanged his white toga for the black toga of his fallen enemy, and picked up the latter’s rifle and cartridge-belt. It felt good to have a real rifle-shaped rifle in his hands once more in place of the buttless firearms of the ants. Just then a voice hailed him from the top of the wall. “What’s the trouble?” Out of the dim twilight below Myles called back: “I shot a sutler, and just as I was about to search his body the light went out. Have you your flash light with you?” “Yes.” “Then come on down and help me search.” The second sentinel, eager for a taste of sutler’s food after weeks of garrison rations, started to scramble down the rope ladder; but as he neared the ground Cabot stepped to his side and put a single bullet through his brain. Out of the semidarkness around him there arose seven forms. They were Buh Tedn and the six Cupian marksmen from the hills. Buh Tedn started to change clothes with the fallen guard, but Cabot stopped him, saying, “No; your limp would give you away. Let one of the others assume the personality of this sentry.” One of the others made the exchange. Then said their leader: “Two of the posts of the guard are now cleared. Do you, marksman, ascend the ladder and walk this beat, impersonating Yuri’s guardsman.” The man did so, while those below cowered close to the wall. Soon Cabot heard a shot to the extreme right of the beat. Then a voice from above called softly: “One less guard, O Cabot. Three sections of the wall are now cleared. I have the body up here.” Myles and one more sharpshooter mounted the parapet; soon all three were walking post with the precision of old war-time practice, while the other five members of the party clung to the rope ladder under the shadow of the wall. Cabot himself walked the leftermost post, and took pains never to meet the adjoining sentry. Thus nearly half a parth of time passed. Finally an officer with a squad approached along the top of the wall to the left. Cabot promptly crowded to the extreme right-hand end of his beat, and cautioned his own adjoining sentinel to remain close at hand. As the squad drew near he sang out, “Halt!” The squad halted. “Who is there?” the earth-man demanded. “Relief.” “Advance one and be recognized.” The officer stepped forward. “Advance relief.” The officer brought the relief forward, halted it again, and called out, “Number four!” Thereat one of the squad stepped from the ranks at port-arms. Cabot himself came to port in unison.
