Not quite entirely had the porcupine unrolled when it discovered its enemy. In that instant the lynx struck. The blow was like a flash of light. The paw, with rigid claws curving like talons, shot under the tender belly and came back with a swift ripping movement. Had the porcupine been entirely unrolled, or had it not discovered its enemy a fraction of a second before the blow was struck, the paw would have escaped unscathed; but a side-flick of the tail sank sharp quills into it as it was withdrawn.
