Whitey gave Mr. Twinkletoes Black a playful chuck under the chin, skipped gleefully across the moonlit roof and back, and sat down sociably by him, before that leisurely pussy turned his head to look scornfully at the youthful—I almost said "speaker," but as all of their conversation is in cat language perhaps "mewer" would be more exact.

"You foolish kitten! Who ever caught a robin in December?"

"My dear boy!"—Twinkletoes' tone made Whitey think he was anything but a dear boy—"When you've lived three years as I have (Whitey was just ten months old) you'll know December when you—er—feel it! It's apt to be cool, and snow—Ugh! Horrid stuff, it is; white—sticks to your feet you know; wet!—" The fussy Mr. Black shook a dainty paw at the very thought, while Whitey listened eagerly, so that the next time he would know how December felt.

"There's one nice thing about it," added Twinkletoes: "the nights are long, and one has time to sing—and sing! One could—"

"Why can't one, Twinky?" asked Whitey hopefully.

"Oh, we might try, but—er—well, bootjacks, you know, hair-brushes, old shoes!—but it's very good exercise, this dodging."

"You said singing," corrected Whitey, rather puzzled. He didn't "know," but never having sung on roofs it was new and sounded thrilling. "Come on," he urged; "let's!" They started in, and their voices rose into awful sleep-destroying discords: "R-r-r-i-ah—M-m-r-r-riee—Mer-r-r-row!" Louder and more banshee-like grew the noise till the expected missiles began to arrive.

Twinkletoes Black was an expert dodger and skipped gracefully from place to place, avoiding the brushes and bottles that dropped from the windows of the tall apartment house next door.

Whitey had retired, silent, after the first old slipper landed heavily on his tail; but he was admiring Mr. Black's prowess with his whole heart. Nevertheless he was glad when the excitement was over with the "song," and they settled down by the chimney once more. The crisp air made him hungry, and again his thoughts turned birdward.

"Let's get some sparrows then," he said, as if there had been no interruption since birds were spoken of. "The early bird, you know, and it will be 'early' if we sit up much later. I never saw an early bird myself, but I suppose there are such things. I prefer a morning nap after these nights on. Haven't much use for early birds, usually." (To hear Whitey talk one would have thought he spent every night singing to the moon—this was his first!)
