Mr. Walker, the superintendent of the telegraphs of the South-Eastern Railway Company, remarks:—“On New Year’s Day, 1850, a collision had occurred to an empty train at Gravesend, and the driver having leaped from his engine, the latter darted alone at full speed for London. Notice was immediately given by telegraph to London and other stations; and, while the line was kept clear, an engine and other arrangements were prepared as a buttress to receive the runaway, while all connected with the station awaited in awful suspense the expected shock. The superintendent of the railway also started down the line on an engine, and on passing the runaway he reversed his engine and had it transferred at the next crossing to the up-line, so as to be in the rear of the fugitive; he then started in chase, and on overtaking the other he ran into it at speed, and the driver of the engine took possession of the fugitive, and all danger was at an end. Twelve stations were passed in safety; it passed Woolwich at fifteen miles an hour; it was within a couple of miles of London when it was arrested. Had its approach been unknown, the money value of the damage it would have caused might have equalled the cost of the whole line of telegraph.” STEAM DEFINED. At a railway station, an old lady said to a very pompous looking gentleman, who was talking about steam communication. “Pray, sir, what is steam?” “Steam, ma’am, is ah!—steam, is ah! ah! steam is—steam!” “I knew that chap couldn’t tell ye,” said a rough-looking fellow standing by; “but steam is a bucket of water in a tremendous perspiration.” IN A RAILWAY TUNNEL. Mr. Osborne in the _Sunday at Home_, says, “I have heard from a friend a strange story of a tunnel, which I will try to tell you as it was told to me. A well-known engineer was walking one day through a tunnel, a narrow one, and as he was going along, supposing himself safe, he thought his ear caught the far-off rumble of a train _in the tunnel_. After stopping and listening for a moment, he became sure it was so, and that he was caught, and could not possibly get out in time. What was he to do? Should he draw himself up close to the side wall, making himself as small as possible, that the train might not touch him. Or should he lie down flat between the rails and let the train pass over him. Being an engineer, and knowing well the shape of things, he decided to lie down between the rails as his best chance. He had to make up his mind quickly, for in a minute or so the whole train came to where he lay, and went thundering over him, and—did him no harm whatever. But he afterwards told his friends, that in that brief moment of time, while the train was passing over, he saw his whole past life spread out like a map, like an illuminated transparency, with every particular circumstance standing out plain.” A QUICK WAY.
