INVISIBLE and sunk beneath the rolling and wooded terrain in Lorraine is a great underground fortification system, 200 miles long, guarding France’s vital industrial area.

The forts, which cost 150 million dollars, are the greatest in the world and defy attack by gas, infantry, artillery, or air bombs. Living quarters, magazines, power stations, and control stations are out of reach of all means of attack. Bulkheads in the underground passages shut out both gas and invaders and armored posts at various points bring additional protection.
