"Captain Jules," continued the girl earnestly, "please, please let's go down to the bottom of this bay. You could take me with you and then there wouldn't be any danger. We have been down together without diving suits and here we are safe and sound on land again! You said you thought there might be pearls in the oyster beds of this bay. We could look, at any rate. I saw the most wonderful things when I was searching for Tania. It seemed as though her dress was caught on the broken spar of an old ship, though, of course, I couldn't be sure. Have there been many wrecks in this bay? Do you suppose it was a ship's spar?" "There are always wrecks on the water, child. And you mustn't be talking nonsense about diving down in this bay along with me," answered Captain Jules severely. He kept his eyes fastened on his diving suit with an affectionate gleam in them. "Maybe, though, I will make a diving party of one and go down in the bay alone. I'd give you the pearls I found down there." Madge shook her head. "That wouldn't be fair," she said, setting her red lips together obstinately. Captain Jules, she felt sure, would be easy to manage. If he did any diving in the Delaware Bay within the next few weeks, he must take her with him. She wrote secretly to New York City to ask what a diver's suit would cost. She was discouraged by the answer, but she did not give up hope. She was also very careful not to let Miss Jenny Ann or Mrs. Curtis know anything of the wild scheme that was evolving in her head. Almost every day the girls saw Captain Jules. Either they went up the bay to call on him, or he made a visit to the houseboat. The old captain never invited the girls inside his house, but they had great frolics in his tidy yard. The captain explained that his house was not neat enough to be seen by young ladies, as it had only a man housekeeper. Even Mrs. Curtis became a little less prejudiced against Captain Jules. She could not but confess that he was a fine old man, though she still did not see why Madge was so much attracted by him. But the girl bided her time. The four girls and their friends went off on long fishing trips with Captain Jules. Sometimes Mrs. Curtis, Tom, and their guest, Philip Holt, went with them. The enmity between Madge and Philip increased every day, nor did Madge any longer make much effort to conceal her dislike for him. Philip Holt had a special reason for his dislike for Madge Morton. He had come to Cape May with the idea of making Mrs. Curtis do an important favor for him upon which his whole future depended. He feared that Madge, who looked upon him as a hypocrite, would find out his true character, tell her friend, and thus ruin his prospects.
