Mr. Chalk flushed. Peckham Rye was one of the nuisances bequeathed by his mother. "I was thinking of the sea," he said, loftily. Mrs. Chalk pounced. "Oh, Yarmouth," she said, with withering scorn. Mr. Chalk flushed deeper than before. "I wasn't thinking of such things," he declared. "What things?" said his wife, swiftly. "The--the things you're alluding to," said the harassed Mr. Chalk. "Ah!" said his wife, with a toss of her head. "Why you should get red in the face and confused when I say that Peckham Rye and Yarmouth are a long way off is best known to yourself. It's very funny that the moment either of these places is mentioned you get uncomfortable. People might read a geography-book out loud in my presence and it wouldn't affect me." She swept out of the room, and Mr. Chalk's thoughts, excited by the magic word geography, went back to the island again. The half-forgotten dreams of his youth appeared to be materializing. Sleepy Binchester ended for him at Dialstone Lane, and once inside the captain's room the enchanted world beyond the seas was spread before his eager gaze. The captain, amused at first at his enthusiasm, began to get weary of the subject of the island, and so far the visitor had begged in vain for a glimpse of the map. His enthusiasm became contagious. Prudence, entering one evening in the middle of a conversation, heard sufficient to induce her to ask for more, and the captain, not without some reluctance and several promptings from Mr. Chalk when he showed signs of omitting vital points, related the story. Edward Tredgold heard it, and, judging by the frequency of his visits, was almost as interested as Mr. Chalk. "I can't see that there could be any harm in just looking at the map," said Mr. Chalk, one evening. "You could keep your thumb on any part you wanted to." "Then we should know where to dig," urged Mr. Tredgold. "Properly managed there ought to be a fortune in your innocence, Chalk." Mr. Chalk eyed him fixedly. "Seeing that the latitude and longitude and all the directions are written on the _back_," he observed, with cold dignity, "I don't see the force of your remarks." "Well, in that case, why not show it to Mr. Chalk, uncle?" said Prudence, charitably. Captain Bowers began to show signs of annoyance. "Well, my dear----," he began, slowly. "Then Miss Drewitt could see it too," said Mr. Tredgold, blandly. Miss Drewitt reddened with indignation, "I could see it any time I wished," she said, sharply. "Well, wish now," entreated Mr. Tredgold. "As a matter of fact, I'm dying with curiosity myself. Bring it out and make it crackle, captain; it's a bank-note for half a million." The captain shook his head and a slight frown marred his usually amiable features. He got up and, turning his back on them, filled his pipe from a jar on the mantelpiece.
