A curdling yell rang out from below, and Ralph saw tiger and pugilist whirling together in a maze of wild confusion.

[CHAPTER XII--THE SUPERINTENDENT'S OPINION]

It seemed as if the escaped circus tiger had disputed the intrusion of Young Slavin just as it had previously that of Ralph.

Whether his belligerent enemy had tried to beat off the animal, or it had attacked Slavin as he attempted to ascend the ladder, Ralph could not tell. One thing was sure, however: the impetuous "champeen" found himself in the mix-up of his life.

The tiger was growling and snarling. Slavin was uttering muffled shouts of terror and pain. Ralph fairly dropped down half a dozen rungs of the ladder.

The wrench with which he had armed himself was heavy, and had a very long handle. Six feet from the floor of the lower tower room, Ralph leaned as far out as he could, holding on to the ladder by one foot and one hand.

Swinging the wrench in the other hand and watching his opportunity, Ralph landed a sturdy whack directly on top of the head of the infuriated tiger.

The blow was severe enough to crack the skull of a human being. The tiger, however, only ducked its head and sneezed, but it relaxed its hold of Slavin.

Ralph saw its great paw cut the air in one lightning-like downward stroke. He saw Slavin, with a curdling shriek, bound through the doorway like a ball. Then the tiger turned, caught sight of his new assailant, and crouched with a malignant snarl, posing for a spring.

Ralph took aim. He let go of the heavy wrench, using it as a missile now. It struck the tiger squarely between the eyes, throwing the animal off its balance. Then with due agility Ralph shot up the ladder like a steeple-jack.
