"Once upon a time," writes Mr. A. W. Blake in the _St. Martin's-le-Grand Magazine_, "the London afternoon mail was made up at a provincial office down West (Chippenham), and despatched to be taken off by apparatus. All proceeded as usual up to the actual point of transfer, when a strange thing happened. Instead of falling soberly into the net, the man in charge was astonished to see the pouch leap high into the air and descend he knew not whither. Search was carefully made along the track of the departed train, but not a vestige of the missing pouch could be seen, and a local inspector who was travelling up the line promised to keep a look-out for it. Just at this time an 'S.G.' was received from the officer in charge of the sorting tender notifying the non-receipt of the pouch. As the mystery seemed to deepen, word was received that a signalman at a level crossing two miles away had noticed the missing article on the top of the train. Quoth the worthy apparatus man: 'If it'll ride two miles, it'll ride two hundred'; and accordingly a wire was sent to the sorting-tender people asking them to search the top of the train, and soon came the reply that the pouch had been found on the roof of the guard's van at Didcot. The train had stopped the regulation time at that hub of the Great Way Round, Swindon, and proceeded on its way without the extraordinary position of Her Majesty's mails being discovered." The occurrence was attributed to the swaying of the carriage, and to the apparatus-net not working quite steadily in consequence. At a later period than the mishap narrated by Mr. Blake, the bags for Oxford and Abingdon, due to be picked up at Wantage by the up night mail travelling Post Office apparatus, and to have been delivered by the same process at Steventon, were not found when the net was drawn in, and it was thought they had been missed; but at Didcot it was discovered they had been thrown over the end of the net and were hanging outside it. Since the opening of the Severn Tunnel in 1883 it has not often been found an absolute necessity to make use of it for the conveyance of mails diverted from the route from South Wales through Gloucester to London; but such was the case in February of the present year (1899), when a tidal wave of forty feet was experienced in the Bristol Channel, which caused serious damage by displacing the railway line between Lydney and Wollaston. The effects of the high tide were disastrous. A wave dashed on to the Great Western Railway with huge force, and so disintegrated the ballasting of the permanent way that the lines were twisted into all manner of shapes. The mails to and from Paddington to South Wales were circulated _viâ_ Bristol and the Tunnel for some time.
