"It's mighty kind of you to take so much trouble for such a stupid comrade, Jack, and let me tell you I appreciate it a heap. Yes, and I'll also get out before dawn in the morning to scour every yard of ground on the way from my house to the post-office. If I could only find that letter I'd be the happiest fellow in Chester, believe me." So they once more donned their caps, and Jack lighted the lantern he had mentioned. While its rays might not be as strong as the glow of the hand-torch, it was able to cover much more ground at a time; and with its help a white envelope half hidden in the long grass could not escape detection. Jack could easily understand just what had happened to Big Bob. He had become so "rattled" when that dreadful suspicion first flashed into his brain after supper that for the life of him he found it impossible to say positively one thing or the other. Now he thought he could remember distinctly pushing the important letter through the slot or drop inside the post-office; and immediately afterwards doubts again assailed him, leaving him worse off. after each experience. If they failed to find the letter, and the postmaster and his assistant had no recollection of having noticed it in cancelling the stamps of the heap that went out with the afternoon mail, then there was no help for it; and poor Bob was doomed to wait day after day, as even weeks went on, always dreading lest each morning was destined to usher in the time when his great crime must come to light, and his punishment begin. They were soon on the spot, and each with his separate light started to carefully examine the long and tangled grass, now partly dead, that lay on either side of the well-worn path across the lots. Doubtless Bob's heart still beat high with hope and anticipation; for when Jack on one occasion started to say something he saw the other whirl around as though thrilled with expectations that were immediately doomed to disappointment. Nothing rewarded their search. Bob might further satisfy himself, and believe he was only doing his duty, by coming out again at peep of dawn and once more covering the ground before giving it up as hopeless; but Jack felt certain nothing would be found. If that letter had dropped from the boy's pocket, then some one must have long since picked it up. He believed he would hear of it if this person, being honest, delivered the letter at the post-office, and told how he had come to find it on the vacant lot. "Well, it's no use looking any further, I guess, Jack," Big Bob now remarked, in a decidedly dejected tone, after they had gone twice over the entire width of the three lots, and without any success attending their efforts.
