In this style we dashed onward, and as I reined in my panting charger before the door of the hotel in G., the stage was just ready to start, the driver being seated on his official throne, whip and reins in hand, looking the picture of impatience. He would have been gone before this, had not the District-Attorney interceded for a short delay. This gentleman was standing in the door of the post-office, appearing very much surprised at my want of punctuality. A hasty explanation produced a smile, and the remark, that it was a "good joke." A doubt which I suggested, as to the safety of examining the mail in the presence of the post master, was set at rest by my companion, who assured me that he was certain of the integrity of this functionary, and also informed me that he had been made acquainted with the object of our call, before my arrival. The post master being a merchant, there was, among the other miscellaneous articles which compose the stock of a country store, a fair assortment of gentlemen of leisure, sitting upon the counter, and reclining in graceful attitudes upon the boxes and barrels. Our unusual movements inspired them with unwonted vigor, and an ardent desire was manifested on their part to know what hidden mystery lurked within the recesses of the mail-bag, which we were about carrying to a room above, in order to be out of the way of observation. Two of these gentlemen, thirsting for knowledge, hastily formed themselves into a committee of investigation, and followed us up stairs, until they were summarily relieved from the discharge of their self-imposed duties by a peremptory intimation from Mr. Pierce, that we wished to be alone for a short time. As soon as we had secured ourselves from intrusion, the bag was hastily unlocked, and its contents turned upon the floor. Each package was taken up, separately and carefully examined, but the all-important one, whose absence would indicate unerringly the guilt of the suspected individual, was not there! This was the most trying and responsible moment of all, as it is always found to be in such investigations--the moment when it is discovered that the trap has been sprung, and the rogue is almost within your grasp. For experience has shown, that missing a "decoy-letter," and establishing in a legal manner the guilt of the individual who is known to have intercepted it, are two very different things. Much caution is requisite in the management of these cases, in order to leave no loop-hole of retreat to the culprit. Too hasty movements might spoil all, by alarming him before he had put it out of his power to account plausibly for the detention of the letter; while a too long delay might enable him to increase materially the difficulty of obtaining direct evidence, by affording him an opportunity of disposing of the necessary proof,--the letter itself, and the contained money.
