But, unfortunately for the kangaroo, this was a blind gully, and Jess knew it. Two minutes later the old-man found himself facing a quite precipitous rocky ascent at the gully's end, and so, there being no alternative that he could see, he turned at bay to face his pursuers. Jess was tremendously excited by the three-mile chase, and it may be that the sound of Finn's powerful strides behind her gave the black hound more than ordinary recklessness. At all events, with practically no perceptible slackening of speed, she flew straight for the old-man's throat, and received the cruel stroke of his hind-leg fairly upon her chest, being flung backwards fully five yards, with blood spouting from her. Now, although Finn had never seen a kangaroo before, and never hunted bigger game than the fox he killed in Sussex, yet he had a full view of poor Jess's terrible reception, and with him, as with all his kind, action follows thought with electrical swiftness. Finn saw in that instant exactly the old-man's method of defence: the cow-like kick, with a leg strong enough to propel its weighty owner five-and-twenty feet in a bound, and armed at its extremity with claws like chisels. Seeing this, and acting upon the hint it conveyed, were a single process with Finn. He swerved sharply from his course, and then leaped with all his strength for the old-man's throat from the slightly higher level of the gully's bank. Now, the old-man weighed two hundred and forty pounds, and measured nine feet from the tip of his snout to the tip of his long tail. But, as against that, he was sitting still, while Finn came at him with the tremendous momentum of a powerful spring from higher ground than that occupied by the kangaroo. And Finn weighed one hundred and forty pounds odd--not of fat and loose skin, but of muscle and bone, without a pound of superfluous flesh. He lived almost entirely on meat. The impact of Finn's landing on the old-man was terrific; but, be it noted, the kangaroo was not bowled over, though he did sway for a moment on his haunches. But it was a terribly punishing hold upon his neck that Finn's jaws had taken, and Finn's great claws were planted firmly in the old-man's side and back. The kangaroo made a desperate effort to free one hind-leg sufficiently from Finn's clinging weight to be able to take a raking thrust at the Wolfhound, by shaking him sideways; and if he had succeeded in this, the result for Finn would have been very severe. Meantime, however, the whole strength of Finn's muscular neck and jaws was concentrated upon dragging the kangaroo's head back, upon breaking his neck, in fact. An old-man kangaroo, such as this one, is generally able to give a pretty good account of himself in the face of four or five hounds; but the hounds he meets are of Jess's type and weight, and not of Finn's sort.
