'Working overseer—thirty or forty thousand sheep—to be at our boundary gate to-night. Wants to go the inner track, where Gateward is saving the grass. No wonder he looks serious.'

'It would not be a bad guess if matters ran in their ordinary groove; but I see signs of a change, with danger signals ahead. That quiet-looking man is Miles Herne, one of the smartest sergeants in the police force. He has been on the track of the two bushrangers. I saw him two or three years ago, and I don't forget people that interest me. He is here to get information, or to give some that may be important.'

'That man a sergeant of police!' exclaimed Bertram, surprised out of his usual equanimity. 'You must surely be mistaken, or he is a consummate artist in disguise.'

'It is the man himself,' persisted she. 'We Australians have sharp eyes—savage attributes, you know. He has captured many a cattle-stealer, they say, in that unassuming bush attire. There is a good deal of talent among our New South Wales troopers. There was Senior-Constable Ross, who used to be told off to catch sly grog-sellers. His get-up was wonderful. Once, Harold told me, he went as one of a pair of blackfellows, and quite outdid the real aboriginal, securing a conviction too. Go down and see the sergeant. I am uneasy about his errand.'


CHAPTER IX

Before the young man made his way into the stable-yard, Pollie meanwhile retreating to her mother's room, the strange horseman had hung up his steed to a post and followed Mr. Gateward to the barracks, in the sitting-room of which unpretending but useful adjunct to the mansion proper Mr. Devereux found them in earnest conclave. They stopped speaking when he entered. The stranger looked searchingly at the young Englishman, who decided, after encountering the keen grey eye and marking the resolute face and wiry, athletic frame, that no ordinary man was before him.

Gateward, after looking round carefully, began in a tone of solemnity and mysterious import. 'Mr. Devereux, this is Sergeant Herne, stationed at Warban, but now on duty out of uniform, for reasons as you'll understand. He's on the track of the men we've heard on.' The stranger saluted in military style, and Bertram instinctively returned the courtesy in like form. 'And bad news he've heard, I'm afraid,' continued Mr. Gateward.

'The sergeant will tell us himself,' interposed Bertram. 'These bushrangers are in the neighbourhood? We heard that before.'

'It's a trifle worse than that, sir,' said the disguised man-at-arms, unbuckling a leather belt and placing a navy revolver, previously concealed by his coat, upon the table. 'Unless my information is false—and I have every reason to think otherwise—the pair of them, the Doctor and Billy Mossthorne, will be here to-night.'
