Here again he paused. That which served him for a mind, that mysterious bundle of intuitions and instincts by which he reckoned time, exchanged confidences, and arranged experiences, informed him that the night was yet young, and that his friend would not yet be arrived. He sat there so still and so long, that if it had not been for his resolute head and the blunt spires of his ears, he would have appeared to an onlooker below as no more than a humpy finial on an otherwise regularly built wall. Now and again the last inch of his tail twitched slightly, like an independent member, as he contemplated his thoughts. Overhead the last glimmer of day was utterly gone, and in the place of it the mysterious glow of night over a city hung high and luminous. He, a town-bred cat, descended from generations of town-bred cats, listened passively to the gentle roar of traffic that stood, to him, for the running of brooks and the sighing of forest trees. It was to him the auditory background of adventure, romance, and bitter war. The energy of life ran strong in his veins and sinews. Once and again as that, which was for him imaginative vision and anticipation, asserted itself, he crisped his strong claws into the crumbling mortar, shooting them, by an unconscious muscular action, from the padded sheaths in which they lay. Once a furious yapping sounded from a lighted window far beneath; but he scorned to do more than turn a slow head in the direction of it: then once more he resumed his watch. The time came at last, conveyed to him as surely as by a punctual clock, and he rose noiselessly to his feet. Then again he paused, and stretched first one strong foreleg and then the other to its furthest reach, shooting again his claws, conscious with a faint sense of well-being of those tightly-strung muscles rippling beneath his loose striped skin. They would be in action presently. And, as he did so, there looked over the parapet six feet above him, at the top of the trellis up which presently he would ascend, another resolute little head and blunt-spired cars, and a soft indescribable voice spoke a gentle insult. It was his friend ... and, he knew well enough, on some high ridge in the background squatted a young female beauty, with flattened ears and waving tail, awaiting the caresses of the victor. As he saw the head above him, to human eyes a shapeless silhouette, to his eyes a grey-penciled picture perfect in all its details, he paused in his stretching. Then he sat back, arranged his tail, and lifted his head to answer. The cry that came from him, not yet _fortissimo_, sounded in human ears beneath no more than a soft broken-hearted wail, but to him who sat above it surpassed in insolence even his own carefully modulated offensiveness.
