An extraordinary accident occurred in the same month, when a coach was burnt on the railway. As the "Regulator" coach, from Bristol to London, was proceeding on one of the uptrains to London, having a quantity of luggage on the top, owing to the large quantity of sparks which issued from the chimney, the luggage took fire, a fact which was only discovered by the coachman (who happened, fortunately, to have remained inside) seeing sparks of fire falling from the top of the coach by the window. The coachman, at the hazard of his life (the train going at the rate of forty miles an hour at the time), got out and clambered on the roof, and by great exertions removed the luggage from the roof, and thereby saved the greater part; but the brisk current of air created by the rapid speed at which the coach was progressing rendered all attempts to extinguish the flame unavailable until the roof was destroyed, when, the embers falling inside, the guard, who had come to the coachman's assistance, succeeded in putting out the fire. In 1832 Mr. Babbage, in his work on the "Economy of Manufactures," suggested a new plan of conveying the mail. The immense revenue of the Post Office would afford means of speedier conveyance. The letter-bags do not ordinarily weigh a hundred pounds, and were then conveyed in bulky machines of many thousand times the weight, drawn by four horses, and delayed by passengers. Mr. Babbage proposed the erection of pillars along each line of road, these pillars to be connected by inclined wires or iron rods, along which the letters inclosed in cylinders attached to the rods by rings are to slide; persons stationed on these columns were to forward the cylinders from each point, after having extracted the contents belonging to their own station. In this manner it was calculated that a letter might be sent (from pillar to post) to the furthest limits of the land in the course of a very small portion of time; from London to York, probably, in an hour or two. In the absence of pillars, and in the interior districts, it was suggested that church-steeples, properly selected, might answer the purpose, and in London the churches might be used for the circulation of the twopenny post. The introduction of the rail and the telegraph has completely remedied the evil Mr. Babbage complained of.
