As it was nearly lost, Rolf used his knife again; that brought the rider back within a mile it seemed, and again the hoof beat faded, te—rump te—rump.

“Bound for Canada all right,” Rolf chuckled to himself. But there was nothing to show whether this was a mere despatch rider, or an advance scout, or a call for reinforcements.

So again he had a long wait. About half-past ten a new and larger sound came from the south. The knife in the ground increased but did not explain it. The night was moonless, dark now, and it was safe to sit very near the road. In twenty minutes the sound was near at hand in five, a dark mass was passing along the road. There is no mistaking the language of drivers. There is never any question about such and such a voice being that of an English officer. There can be no doubt about the clank of heavy wheels—a rich, tangy voice from some one in advance said: “Oui. Parbleu, tows ce que je sais, c'est par la.” A body of about one hundred Britishers, two or three wagons, guns, and a Frenchman for guide. Rolf thought he knew that voice; yes, he was almost sure it was the voice of Francios la Colle.

This was important but far from conclusive. It was now eleven. He was due at the canoe by midnight. He made for the place as fast as he could go, which, on such a night, was slow, but guided by occasional glimpses of the stars he reached the lake, and pausing a furlong from the landing, he gave the rolling, quivering loon call:

Ho-o-o-o-ooo-o Ho-o-o-o-ooo-o. Hooo-ooo.

After ten seconds the answer came:

Ho-o-o-o-o-o-o-o Hoo-ooo.

And again after ten seconds Rolf's reply:

Hoo-ooo.

Both his friends were there; Fiske with a bullet-hole through his arm. It seemed their duty to go back at once to headquarters with the meagre information and their wounded comrade. But Fiske made light of his trouble—it was a mere scratch—and reminded them that their orders were to make sure of the enemy's movements. Therefore, it was arranged that Seymour take back Fiske and what news they had, while Rolf went on to complete his scouting.
