"Tell us what you think, Madge," insisted Miss Betsey. "Why, I was beginning to feel proud of the boy, his manners have improved so much since he came on this trip. And I have been saying to myself that if I had believed in the boy and tried to help him, as you have done, perhaps he might have been less surly years ago. Some day I may tell you children more of the lad's history."

"Miss Betsey," Madge's voice was very grave, "to tell you the truth, I don't know what to think. I know that there are some things that point toward David's being a thief. But, just the same, I don't believe he is one. You know I have always been sorry for David, Miss Betsey, ever since he pulled me out from under Dr. Alden's buggy, when I was trying to spoil your lawn, as the donkeys did Miss Betsey Trotter's in 'David Copperfield.' And somehow"—she paused reflectively—"I believe in him still. I know that David Brewster wouldn't steal! It may be my intuition that makes me say this; I have no real reason for thinking it. I trust David, trust him fully. I am sure that he is absolutely honest."

Miss Betsey patted Madge's auburn head almost affectionately. She felt nearly fond of her for her loyalty toward David. "We won't, any of us, speak of suspecting any one, children," she concluded. "You are not to mention having seen David Brewster come out of my room. I would not have suspicion rest on the boy wrongfully for a great deal; it might ruin his whole future life. But we must be very careful; say nothing and watch! There are sure to be other developments that will point toward the real thief. If we do see or hear anything else that seems suspicious, then we owe it to Mr. and Mrs. Preston to take them into our confidence. We must remember that their property was stolen as well as mine, and that they have taken us into their household and treated us as members of their own family. Much as I may wish it," Miss Betsey lowered her voice solemnly, "I feel that we have no right to shield David if he is at fault. But"—Miss Taylor's voice was even more serious—"it would be a far more wicked thing for us to accuse the boy if he is guiltless."

Miss Betsey rose to go. In spite of her funny, old maid appearance and her usually severe manner toward Madge, that young woman flung her arms around the spinster's neck and hugged her warmly. "You are perfectly splendid, Miss Betsey," she whispered. As Miss Betsey tip-toed cautiously out of the room, Madge blew a kiss toward her retreating back. "You can just lecture me, after this, as much as you like. And I promise, I promise"—Madge hesitated—"I promise not to like it a bit better than I do now," she ended truthfully.

Then Madge turned to Phil, her rock of refuge. "Phyllis Alden, if David Brewster stole from Miss Betsey or Mrs. Preston, I don't care what excuse he has, I shall never forgive him, or myself for bringing him on this boat trip. Oh, dear me! I wish dear old Tom were here! I would ask Tom to ask David to clear things up. I suppose if I try to talk to David Brewster, he will bite my head off."

"Come to bed this minute, Madge, and don't talk to anybody about anything until you know more," commanded Phil stolidly. And Madge obeyed.


CHAPTER XVIII
DAVID'S MYSTERIOUS ERRAND

POOR David Brewster was facing a more difficult problem than he ever had had to conquer in his life. He must manage to get over to the old coal mine, bring back the Preston silver and as much of Miss Betsey's money as he could force the thief to leave behind him, without being noticed or suspected of any unusual design. The jewels that David had already returned to Miss Betsey had been in charge of the old gypsy woman; David had found them on his first visit to her. But to carry back a quantity of old family silver, some of it in fairly large pieces, was not so simple a task. Yet David had one thing in his favor: Harry Sears and Jack Bolling had both left the Preston farm. After Harry's encounter with David, and the latter's frank account of his own part in the fight, Harry had not cared to linger at the farm. He knew that some day Madge and Phyllis Alden would find out why David had been tempted to fight. Harry Sears had no desire to recount his own unsuccessful attempt to act the part of "Paul Pry," so Harry and Jack had gone on to join Tom Curtis and George Robinson, and the four boys were to come on to the houseboat party in a few days.

David Brewster knew that whatever he had to do must be done quickly. So he borrowed a horse and cart from Mr. Preston a day or so after Miss Betsey's midnight talk with Madge and Phyllis. He did not explain what he wished with the horse. However, his host asked no questions, for Mr. Preston had entire faith in the boy.
