"When there's shadows in the trees," said the old man, "there's times when you can't tell whether they're men or not. That's what I mean. I'm only saying that I didn't hear anyone. I'd have heard horses."

"The man's a hatter," the sergeant remarked as the troop galloped off towards the ranges. "As mad as a March hare."

The other grinned cheerfully. "Still there's a lot in what he said," he answered. "Now that about the fire——"

"I wonder why they lighted it," the sergeant cut-in.

"Don't know," the other said. "What's the sense of worrying anyway? We'll know soon enough. But don't you think we should have brought the old chap along with us?"

The sergeant shook his head. "What'd be the good?" he said. "He couldn't do any more than he's done already."

He swung round in his saddle and faced the troop. "Now, men," he said, "we've got to put our best foot foremost. Those 'rangers are somewhere ahead of us, making for the mountains. Keep your eyes skinned, for you never know the minute we'll catch up to them. They can't have such a big start of us, and they're heavily loaded at that."

The troopers unslung their carbines and examined the loading, then, satisfied that every preparation had been made, they set spurs to their horses and cantered up the track that led to the ranges.

It was Mr. Abel Cumshaw who first discovered the pursuers. Early in the afternoon the two men commenced to ascend the mountains proper. Just before they disappeared into the belt of timber that fringed the slopes the younger man turned in his saddle and cast one last backward glance at the valley they had left beneath them. Far away below them, in among the misty shapes of the distant trees, he caught a glimpse of a collection of dark little dots whose unfamiliar look puzzled him. He called Mr. Bradby's attention to them, and that gentleman glanced at them in an offhand way and pronounced them to be kangaroos.

"Come on," he added in a different tone. "Hurry up with you there!"
