But to-night it was better. One by one the ghoulish muzzles emerged, peered into the darkness, and were satisfied; then the clumsy, ill-balanced bodies, entangled in loose-folded leathern cerements--the noctule's wing-spread measures a full foot; lastly, the webbed curving triangle of feet and tail. [Illustration: THE NOCTULES CAME FROM THE HOLLOW OF THE OLD CHESTNUT.] Each, as it blundered free, clung, for a space, head downwards to the bark, then slacked the grip of its ten toes, unhooked its thumbs, dropped, and flew. Never was flight more graceful, never more perfectly controlled. For fear of the swallows, the summer beetles fly by choice at twilight; even then they must needs fly low, for the noctule never misses, and the crunch of his teeth in a beetle's horny back is all he knows of music. The stoat came from a tree which was even more decrepit than the chestnut. It had been an elm once. For four centuries it had defied the elements, towering full fifty feet in rugged, imperial grandeur. The elements had outstayed it. All that remained was a caverned stump, whose jagged summit pointed, like an accusing finger, to the sky. But, from a stoat standpoint, the stump was unsurpassable. There were three exits from the hollow base. Up the shaft there was yet another. Thick brambles fringed it on every side, and in those brambles were many birds' nests. The stump was an ideal nursery; as such the stoat had employed it. He had left to its friendly protection his family of six, with a young rabbit to keep them occupied. He, himself, was now in quest of frogs. The hedgehog bore on his back clear tokens of his last retreat. A dozen withered leaves were clinging to his spines. The nearest pile of such lay heaped against the hen-house. The hedgehog footed through the knotgrass slowly, grubbing with his snout to right and left of him. Sometimes, when cover failed, he broke into a bow-legged run. The squirrel came from high up in the beech tree--the second fork from the top. There he had built what he called a nest, but what humans, with greater nicety of diction, call a drey. Speak not of squirrel's "nest" to sportsmen; to speak of fox's "burrow" were hardly less heinous. The drey was eminently satisfactory, for, in the summer months, it was completely hidden. Yet three days inside it had been more than sufficient for the squirrel. He was cold, hungry, and cramped in every limb. To quicken the blood within him, he flung himself at lightning speed from bough to bough, from tree to tree, up and down the branches, in and out the maze of dripping foliage, until his every hair was tipped with a raindrop, and he was almost weary. Then he paused a moment for breath and shook himself, dog-fashion.
