'Where is he?' muttered Billy to himself, and at the next second be knew. A faint hiss sounded in the corporal's very ear. Billy thought of the vipers that swarmed on some parts of the heath, and jumped round in affright, and at that instant a ball was flipped into his eye from some unseen thumb and finger. 'Hang it all!' said Billy. 'I'm bagged! Where are you?' 'Wot cheer, brother!' came a husky whisper from the centre of the turf-stack. Billy gave the stack a kick, and it collapsed, and revealed Chippy crouching there with a cheerful grin on his face. He had built himself round with turves, and lay securely hidden. 'Nice little lot o' flags ye've got!' murmured Chippy. 'It'll be a case of all round me hat this time.' Billy felt disgusted at the neat way he'd been taken in, but he proceeded to hand his flags over at once. Presently his usual friendly smile broke out. 'After all, Slynn,' he said, 'it was a fair catch. What a jolly artful dodge to draw me up with your patrol call!' 'Not bad,' chuckled Chippy. 'I know'd ye'd think there was a lost Raven a-flitterin' about, an' then yo'd come to look 'im up.' 'Well, I must be off and report myself,' said Billy, and off he strolled, leaving the leader of the Raven Patrol to fix in his hat the fine trophy of flags he had captured. Chippy was some little time at his task, for he had now five black flags--his own and four recaptured from Billy--and five yellow flags; four he had already seized, and the fifth was Billy's own original badge. He was scarcely ready to renew his quest, when a long, shrill call rang from Mr. Elliott's whistle. This signal had been arranged for the moment when only two rival scouts remained in the field. Now the battle must be finished during the next twenty minutes, or the contest was drawn. Some such sharp close was necessary, or a pair of over-cautious opponents might scout about or hide up and never find each other. The two left in were the rival leaders. Just about the time that Billy was drawn into range, Dick bagged the other Raven, and when Mr. Elliott saw the two defeated scouts running for the Beacon he sounded his whistle. The scouts out of the game had not had a dull time of it. If they were not in the combat, they enjoyed a splendid view of it as spectators. From the top of the hill almost every movement of the fighters below could be watched, and the excitement now rose high among both Wolves and Ravens as they saw their leaders running through the cover below in eager search of each other.
