“Horse down!” snapped Yorke tersely.  “Hell!” he added, “looks like a man there, too! come on quick!”

Responding to a shake of the lines and a fierce thrust of the spurs, their horses leapt forward and they raced towards their objective.

“Steady! steady!” hissed Yorke, checking his mount as they drew near the fallen animal and its rider, “pull Fox a bit, Red!  Mustn’t scare the horse!”

Slackening into a walk, they flung out of saddle, dropped their lines, crouched, and crept warily forward.  The horse, a big, splendid seal-brown animal, had fallen on its right side, with its off fore-leg plunged deep in a snow-filled badger-hole.  The body of the man lay also on the off-side with one leg under his mount.  The stiffened form was a ghastly object to behold, being literally encased in an armour-like shell of frozen, claret-coloured snow.

At the approach of the would-be rescuers the poor brute whinnied pitifully and made another ineffectual attempt to rise.  Yorke flung himself onto the head and held it down, while George dived frantically for the man’s body, and tugged until he had got the leg from under.

“Hung up! by God!” gasped the former, “his foot’s well-nigh through the stirrup!”

Redmond, ex-medical student, made swift examination.  “Dead!” he pronounced with finality, “Good God! dead as a herring!  The man’s been dragged and kicked to death!” He made a futile effort to release the imprisoned foot.

“No! no!” cried Yorke sharply, “no use doing that if he’s dead.  Coroner’s got to view things as they are.”

The horse began to struggle again painfully.  Peering down the badger-hole they could see the broken bone of its leg protruding bloodily through the skin.  Yorke released one hand and reached for his gun.

“Poor old chap!” he said, “we’ll fix you.  Quick Red! pull the body as far back as the stirrup-legadeiro’ll go!  That’ll do!  There, old boy! . . .”

And with practised hand he sent a merciful bullet crashing through brain and spinal cord.  The hind legs threshed awhile, but presently, with a muscular quiver they stiffened and all was still.  Yorke, releasing his hold struggled to his feet, and the two men stared pityingly at what lay before them.  What those merciless, steel-shod hoofs had left of the head and the youthful body indicated a man somewhere in his twenties.  His ice-bound outer clothing consisted of black Angora goatskin chaps and a short sheepskin coat.

“Can’t place him—­like this,” muttered Yorke, after prolonged scrutiny, “but I seem to know the horse.”

Suddenly he uttered a sharp exclamation—­something between a groan and a cry.  Redmond, startled at a new horror apparent on the other’s ghastly face, clutched him by the arm.

“What’s up?” he queried tensely.

Yorke struggled to speak.  “Fox!” he gasped presently—­“this morning. . . .  I never told you.  My God!—­You might have got hung up like this, too.”
