A dog trotted up, spied him, and came to sniff.

“Good-bye, boy!” said Bill chattily.

The dog was taken aback. Hitherto, in his limited experience, birds had been birds and men men. Here was a blend of the two. What was to be done about it? He barked tentatively, then, finding that nothing disastrous ensued, pushed his nose between two of the bars and barked again. Any one who knew Bill could have told him that he was asking for it, and he got it. Bill leaned forward and nipped his nose. The dog started back with a howl of agony. He was learning something new every minute.

“Woof-woof-woof!” said Bill sardonically.

He perceived trousered legs, four of them, and, cocking his eye upwards, saw that two men of the lower orders stood before him. They were gazing down at him in the stolid manner peculiar to the proletariat of London in the presence of the unusual. For some minutes they stood drinking him in, then one of them gave judgment.

“It’s a parrot!” He removed a pipe from his mouth and pointed with the stem. “A perishin’ parrot, that is, Erb.”

“Ah!” said Erb, a man of few words.

“A parrot,” proceeded the other. He was seeing clearer into the matter every moment. “That’s a parrot, that is, Erb. My brother Joe’s wife’s sister ’ad one of ’em. Come from abroad, they do. My brother Joe’s wife’s sister ’ad one of ’em. Red-’aired gel she was. Married a feller down at the Docks. She ’ad one of ’em. Parrots they’re called.”

He bent down for a closer inspection, and inserted a finger through the railings. Erb abandoned his customary taciturnity and spoke words of warning.

“Tike care ’e don’t sting yer, ’Enry!”
