"Six registered letters for Mr. Warfield," said the postmistress at Greenbrier, as if there was a conspiracy to keep this fact fresh in Little Snap's mind. However, he heard nothing further of the precious letters until he had accomplished his hard day's work and given the mail pouch into the hands of Mr. Rimmon at Six Roads. Nothing unusual had occurred at home during the day, and after supper the postboy went into the post office, where he found a dozen or more men gathered. Whatever the subject of their conversation had been, it was suddenly dropped upon his appearance. He did not intend to stop, and inquiring if there was any mail for those at his home, he was turning away, when he heard Mr. Warfield, in his loud tone: "Only three, Mr. Rimmon? I am sure there ought to be more." "That is all reaching this office, Mr. Warfield." "They may get along to-morrow, but I was expecting three or four others, and two of them I was certain would come to-day. You must have overlooked them." Little Snap's attention was held by these words, and instantly his mind reverted to the six registered letters. Had one-half of them failed to reach their destination? In the midst of his speculations Mr. Warfield approached him, to inquire about his day's trip. "Don't fail to let me know if anything unusual happens, Dix, though I hope you will get along without further trouble. Perhaps you will. By the way, I do not suppose you know anything about my registered letters?" "I would not be expected to, would I, Mr. Warfield?" replied Little Snap, answering him with another question. "No; I hardly suppose you would. Still you want to keep your eyes and ears open. I had some letters due to-night which have not come. But to-morrow will bring them or explain the reason of their not coming." At the first opportunity Little Snap inquired of Mr. Rimmon concerning the letters, to learn that there were really three less than had passed through the offices on his route as far as Greenbrier to his knowledge. "Why, there were six, Mr. Rimmon, started from Loop, and Budd Grass said there were as many at her office." "What! That don't seem possible," replied Mr. Rimmon, in great surprise. "Who would dare to stop them?" "That is what is puzzling me." "Say, Dix," cried the postmaster, abruptly, "if I were you I wouldn't mention this to any one else. Don't you see, it looks bad for you." "But I haven't had the handling of them." "I know; but at the same time it might cause a suspicion against you. I hope they will come to-morrow. I won't say anything about them, and we will see what a day brings forth." Not wishing to give his mother any unnecessary alarm, Little Snap said nothing of the missing letters at home, though he was troubled not a little in his mind concerning their fate.
