_And be it further enacted_, That if any person shall, knowingly and wilfully, obstruct or retard the passage of the mail, or of any driver or carrier, or of any horse or carriage, carrying the same, he shall, upon conviction for every such offence, pay a fine not exceeding one hundred dollars; and if any ferryman shall, by wilful negligence, or refusal to transport the mail across any ferry, delay the same, he shall forfeit and pay, for every ten minutes that the same shall be so delayed, a sum not exceeding ten dollars. It is obviously right that the pleasure of an individual should not weigh for a moment in the balance, with the interests of thousands depending as they do, in a degree, upon the prompt transmission of correspondence. Were all the consequences of simply impeded delivery of important letters to be made known, the record would be a melancholy one indeed. In crowded cities especially, through whose streets the mails are many times a day conveyed to steamboats and rail road stations, it is particularly important that all obstacles in their way should be removed; and pains have been taken to make the law on this subject generally understood, so that at the approach of the wagon bearing the magic characters "U. S. Mail," the crowd of vehicles which throng the busy streets, separate to the right and left, and do homage to that supreme power--the Public Good. A curious trial under the law I have cited, was held in Boston before the United States Court, about two years since. It appears that the regular mail-coach from Worcester to Barre, left the former place on the afternoon of January 8, about half past four, full of passengers, and ornamented, as well as distinguished, by the words "U. S. Mail," painted in conspicuous letters on both sides of the foot-board. The passengers were beginning to develope those sparks of sociability which are elicited by the collisions with one another, and the stimulus to the brain resulting from sundry jolts inseparable from the vicissitudes of stage-coach traveling. In other words, the coach had proceeded about two miles, when, arriving at a place where there was some ascent in the road, it overtook three one-horse wagons, which made way for it to pass. Very soon, however, the two occupants of the hindmost wagon, (whom we will call Stark and Baker,) whipped up their steed, and rushed by the coach, like some saucy cutter shooting ahead of a seventy-four. After this demonstration, their horse, having gained four or five rods on the coach, subsided into a walk.
