At first it had seemed to Shannon a mad thing to attempt, but as she watched and realized what Custer sought to accomplish, she understood the wisdom of it. If he could check the flames here with a couple of furrows, he might gain time to stop its eastward progress to the broad pastures filled with the tinder-dry grasses and brush of late August.

Already some of the men were working with shovels, just above the furrow that the plow was running, clearing away the brush and throwing it back. Shannon watched these men, and there was not a shirker among them. They worked between the fierce heat of the sun and the fierce heat of the fire, each one of them as if he owned the ranch. It was fine proof of loyalty; and she saw an indication of the reason for it in Custer’s act when he turned the Apache over to the oldest man, in order that the veteran might not be called upon to do work beyond his strength, while young Pennington himself undertook a dangerous and difficult part in the battle.

The sight thrilled her; and beside this picture she saw Wilson Crumb directing a Western scene, sending mounted men over a steep cliff, while he sat in safety beside the camera man, hurling taunts and insults at the poor devils who risked their lives for five dollars a day. He had killed one horse that time and sent two men to hospital, badly injured—and the next day he had bragged about it!

Now they were across the ravine and moving along the east side on safer footing. Shannon realized the tension that had been upon her nerves when reaction followed the lessening of the strain—she felt limp and fagged.

The smoke hid them from her occasionally, as it rose in cloudlike puffs. Then there would be a break in it, and she would see the black coats of the Percherons and the figures of the sweating men. They rounded well down the east side of the ravine and then turned back again; for the other team, with easier going, would soon be up on that side to join its furrow with theirs. They were running the second furrow just above the first, and this time the work seemed safer, for the horses had the first furrow below them should they slip—a ridge of loose earth that would give them footing.

They were more than halfway back when it happened. The off horse must have stepped upon a loose stone, so suddenly did he lurch to the left, striking the shoulder of his mate just as the latter had planted his left forefoot. The ton of weight hurled against the shoulder of the near horse threw him downward against the furrow. He tried to catch himself on his right foot, crossed his forelegs, stumbled over the ridge of newly turned earth, and rolled down the hill, dragging his mate and the plow after him toward the burning brush below.

Jake at the plow handles and Custer on the lines tried to check the horses’ fall, but both were jerked from their hands, and the two Percherons rolled over and over into the burning brush. A groan of dismay went up from the men. It was with difficulty that Shannon stifled a scream; and then her heart stood still as she saw Custer Pennington leap deliberately down the hillside, drawing the long, heavy trail-cutting knife that he always wore on the belt with his gun.

The horses were struggling and floundering to gain their feet. One of them was screaming with pain. The girl wanted to cover her eyes with her palms to shut out the heart-rending sight, but she could not take them from the figure of the man.

She saw that the upper horse was so entangled with the harness and the plow that he could not rise, and that he was holding the other down. Then she saw the man leap into the midst of the struggling, terrified mass of horseflesh, seeking to cut the beasts loose from the tangled traces and the plow. It seemed impossible that he could escape the flying hoofs or the tongued flames that licked upward as if in hungry greed to seize this new prey.

As Shannon watched, a great light awoke within her, suddenly revealing the unsuspected existence of a wondrous thing that had come into her life—a thing which a moment later dragged her from her saddle and sent her stumbling down the hill into the burning ravine, to the side of Custer Pennington.
