Loudon swung into his saddle and spurred his mount. The animal responded gamely, but a pitifully slow lope was the best speed it could shake out of its weary legs. Laguerre's pony was in worse case. The short halt had stiffened his knees slightly and he stumbled at every other step. The two men lolloped jerkily downstream. Rounding a sharp bend, they came in sight of the cut bank where the dusty stranger had dropped his gun. Neither man nor horse was visible.

"By gar!" exclaimed Laguerre. "By gar!"

Just then his horse stumbled for the last time, fell on its knees, and rolled over on its side. Laguerre flung himself clear and bounced to his feet. The pony struggled up, but Laguerre did not remount. He dragged his rifle from the scabbard and ran forward on foot to rejoin his comrade. Loudon was leaning over the saddlehorn examining the spot where the dusty man had left his horse.

"Ground's kind o' hard," said Loudon, "but it looks like he'd headed for that flat."

"He go dere all right!" exclaimed Laguerre, excitedly. "Come on, Tom!"

Running awkwardly, for cow-country boots are not fashioned for rapid locomotion, Laguerre led the way toward a broad meadow fifty yards away. Once in the meadow the trail was easier to follow. The meadow was at least a quarter-mile wide, and woods bordered it on three sides.

The trail led straight across it, and on into the forest. The trees did not grow thickly, and Laguerre, his eyes on the ground, threaded his way in and out between the trunks at an ankle-straining trot. He had excellent wind, had Telescope Laguerre. Loudon was forced to employ spurs and quirt in order to keep up with him.

Four hundred yards deep in the forest they saw ahead an opening in the trees. A minute later they charged into a large meadow. In the middle of the meadow was an ancient shack, doorless, the roof fallen in, flanked by a corral which gave evidence of having been recently repaired.

"Somethin' movin' in that corral," said Loudon, and dragged out his gun.

Then, in half a watch-tick, a man on a chestnut horse flashed across the open space between the corral and the shack. Loudon and Laguerre swung to one side, but the man did not immediately reappear on the other side of the shack. A few steps farther and they saw him. He was riding directly away from them and was within fifty yards of the forest.
