The thunder of his hoofs was in their ears. They did not speak again as they came to the steep bank down to the open creek. There, just before them, was an old hollow stump, perhaps ten feet high, with the opening on the creek side. All three of them knew it well.

As Helen went over the bank and disappeared on one side of the stump, Tom darted around the other side. Ruth, with the red cap in her hand, stumbled over a root and fell to her knees. She was right beside the hollow stump, and Helen's cap caught in a twig and was snatched from her hand.

As Ruth scrambled aside and then fairly rolled over the edge of the bank out of sight, the cap was left dangling right in front of the stump. The bull charged it. That flashing bit of color was what had attracted the brute from the start.

As the three friends dived over the bank—and their haste and heedlessness carried them pell-mell to the bottom—there sounded a yell behind them that certainly was not emitted by the bull. Goodness knows, he roared loudly enough! But this was no voice of a bull that so startled the two girls and Tom Cameron—it was far too shrill.

"There's somebody in that tree!" yelled Tom.

And then the forefront of the bull collided with the rotten old stump. Taurus smashed against it with the force of a pile-driver— three-quarters of a ton of solid flesh and bone, going at the speed of a fast train, carries some weight. It seemed as though a live tree could scarcely have stood upright against that charge, let alone this rotten stump.

Crash!

The rotten roots gave way. They were torn out of the frozen ground, the stump toppled over, and, carrying a great ball of earth with it, plunged down the bank of the creek.

Tom had clutched the girls by their hands again and the three were running along the narrow shore under shelter of the bank. The bull no longer saw them. Indeed, the shock had thrown him to the ground, and when he scrambled up, he ran off, bellowing and tossing his head, in an entirely different direction.

But the uprooted stump went splash! into the icy waters of the creek, and as it plunged beneath the surface—all but its roots—the trio of frightened friends heard that eyrie cry again.
