Almost recklessly they darted down the cañon, slipping swiftly along from bowlder to bowlder, but before they had covered half the distance the panther made his spring.

He made it magnificently. He had scented the blood of that antelope from far away, and he may have suspected that it was not a living one, but his instincts had forbidden him to approach it otherwise than with caution. He would not have been a cougar if he had not made a spring in seizing upon his prey.

They are nothing in the world but giant cats, after all, and they catch their game precisely as our house-cats catch their mice. If anybody wants to know how even a lion or a tiger does his hunting, "puss in the corner" can teach him all about it.

"He will tear it all to pieces!"

"No, he won't, Steve. We can get a bead on him from behind that rock yonder. He'll be too busy to be looking out for us for a minute or so."

That was true, and it was a bad thing for the great "cat of the mountains" that it was so, for the two hunters got within a hundred yards of him before he had done smelling of the big-horn, in which he had buried his sharp, terrible claws.

"Now, Steve, I won't miss my shot this time. See that you don't."

Steve took even too much care with his aim, and Murray fired first.

He did not miss; but a cougar is not like a deer, and it takes a good deal more to kill him. Murray's bullet struck a vital part, and the fierce beast sprung from the bowlder with a ferocious growl of sudden pain and anger.

"I hit him! Quick, Steve!"
