.A Tunnel Across the English Channel?

.SINGSTAD -The Man From Down Under!
by Richard H. Parke
ONE June night two years ago a fire was raging 85 feet beneath the surface of New York’s East River.

.When Rivers Run Wild

.TUBING THE ENGLISH CHANNEL
By DAVID WALESDOVER, England, is within gunshot of Calais, France. The German 42-centimeters could drop a shell across the 22 miles of water that intervene. The floor of the Straits of Dover is white chalk, underlaid by a stratum of chalk and clay. Beneath, to a depth of 208 feet, lies a ledge of gray chalk, very solid, of the same general character as that quarried in France for use in making cement. This substance is easy to bore, is self-sustaining, and is practically water-tight.
