"That was all right. Now let me see," added Silas, consulting his books; "fifty-five dozen live quails at three fifty per dozen--one ninety-two, fifty; less twenty-eight, leaves one sixty-four, fifty. Just step around here and sign this receipt." David obeyed like one in a dream. He put his name to the receipt, and, scarcely knowing what he was about, thrust the package of money which Silas handed him into his pocket and walked out of the store. "There goes the proudest boy in the United States," said the grocer. Yes, David was proud, but he was grateful, too. He was indebted to Don and Bert for his good fortune, and he was sorry that he could do nothing but thank them when they came home. He went straight to the cabin, and to his great surprise and joy found his mother there. She was alone in the house, but David, profiting by his past experience, made a thorough examination of the premises before he said a word to her. Having thus made sure that Dan was not about, he pulled out his package of greenbacks and laid it in his mother's lap. There was joy in the cabin that day. If David had never before realized that it is worth while to keep trying, no matter how hard one's luck may be, he realized it now. We will leave him in the full enjoyment of his success, promising to bring him to the notice of the reader again at no distant day, in the concluding volume of this series, which will be entitled THE MAIL CARRIER. THE END.
