UNDER THE CHANNEL

The illustration shows the proposed laying of a "cut and cover"
prefabricated tunnel on the Channel bottom with the aid of a
DeLong self-elevating construction platform.

SIR EDWARD WATKIN was a vociferously successful promoter from the Midlands. The son of a Manchester cotton merchant, Watkin had passed up a chance at the family business in favor of railways in the early days of the age of steam, and it is a measure of his generally acknowledged shrewdness at railway promotion that in his mid-twenties, having become secretary of the Trent Valley Railway, he negotiated its sale to the London North Western Railway at a profit of £438,000. Now in his early sixties, Watkin was chairman of three British railway companies, the Manchester, Sheffield Lincolnshire Railway, the Metropolitan (London) Railway, and the South-Eastern Railway—the last-named being a company whose line ran from London to Dover via Folkestone—and one of his big current schemes was the formation of a through route under a single management—his own, naturally—from Manchester and the north to Dover. It was while he was busily promoting this scheme that Watkin caught the Channel-tunnel fever. He realized that part of the land the South-Eastern Railway owned along its line between Folkestone and Dover lay happily accessible to the ribbon of Lower Chalk that dipped into the sea in the direction of Dover and stretched under the bed of the Strait, and it wasn't long before he was conjuring up visions of a great system in which his projected Manchester-Dover line, instead of stopping at the Channel shoreline, would carry on under the Strait to the Continent.
