With a shrill snarl the pug rushed in. At the same instant the puma sprang, making a splendid tawny curve through the air, and alighted ten feet behind his antagonist's tail. There he wheeled like lightning and crouched. But the pug, enraged at being balked of his vengeance, had also wheeled, and charged again in the same half second. In the next, he had the puma by the throat. With a dreadful screech the great beast rolled over on his side and stiffened out his legs. The pug drew off, eyed him critically to make sure that he was quite dead, then ran, barking shrill triumph, to take possession of the victim's place. Then the whip cracked once more. Whereupon the puma got up, trotted back to his pedestal, mounted it, and tucked the pug protectingly away between his great forepaws. The applause had not quite died away when a towering, sandy-brown bulk appeared in the entrance to the cage. Erect upon its hind legs, and with a musket on its shoulder, it marched ponderously and slowly around the circle, eying each of the sitting beasts--except the wolf--suspiciously as it passed. The watchful eyes of both Signor Tomaso and Hansen noted that it gave wider berth to the puma than to any of the others, and also that the puma's ears, at the moment, were ominously flattened. Instantly the long whip snapped its terse admonition to good manners. Nothing happened, except that the pug, from between the puma's legs, barked insolently. The sandy-brown bulk reached its allotted pedestal,--which was quite absurdly too small for it to mount,--dropped the musket with a clatter, fell upon all fours with a loud _whoof_ of relief, and relapsed into a bear.
