"Well, of course I can't tell for certain," said Madge. "I can only guess. But it seems as if it must have fallen out of Lewis's pocket."

"Then you think he took our things out of the treasure-hole?" cried Betty. "He never could have been so wicked as to steal them, and then come pretending he was so sorry for our loss and wondering where they had gone!"

"Perhaps he didn't actually mean to steal them, only to tease us," suggested Madge. "And I feel sure now that he took the rope-ladder," she continued. "You know he pretended at the time that he couldn't get up the wall without it; but that was only to deceive us. He had those iron railings for ladders, though he said nothing about them until later."

"Oh, Madge!" exclaimed the twins. They could think of nothing else to say. The contemplation of such deliberate perfidy was too overpowering. The more they recalled Lewis's dark hints and malicious suggestions about other people, the more disgusted they felt with him, and the more vexed with themselves for having been so completely deceived. "We might have known there was something wrong when he made us promise not to say anything about him!" they said. "Never again will we have a secret friend!"

Captain West went several times to see Lewis during his long illness, and did his best to make the unfortunate boy understand the reason why he was an unfit companion for other children. At first Lewis seemed to regard his untruths and deceptions merely in the light of very clever jokes; but gradually some faint sense of shame appeared to steal over him, though whether on account of his faults or only because they had been discovered, Captain West could not very well make out.

"What will become of Lewis Brand?" asked the children one day when their father had just returned from visiting him.

"Directly he is well enough to walk he is going to live with a gentleman who has great experience with boys, and who will do his best to counteract the faults that you all find so shameful in Lewis," said Captain West. "But in justice to the poor boy I must add one thing. He was much neglected as a little child, and had none of the advantages of an affectionate and careful training. Now, in proportion to his opportunities, perhaps he did not behave worse than certain children who, with no excuses at all, tried to deceive—"

"Do you mean us?" interrupted Madge, with a very red face. She did not at all appreciate being compared in any way with Lewis, for whose conduct she felt great contempt. And yet there was a certain element of truth in her father's words that could not be ignored.

"Well, we will say no more about that," continued Captain West cheerfully. "I think after what has happened I can trust you all not to embark again on secret friendships with strangers?"

"No! Indeed we will not!" cried the three children. And they kept their resolution.
