Charting a World at War 619 Umbrella Keeps the Sun from His Telescope-Comfort Is Secondary A survey topographic party from the Cowie maps Chesapeake Bay (page 621). The officer draws his lines directly on the field chart, resting on the plane table beneath his alidade. The hydrographic group in the boat resorts to old-fashioned hand sounding, for the water is too shallow for a fathometer. George H1. Copeland A Tombstone in the "Graveyard of the Atlantic"-Cape Hatteras The wreck of the four-master G. A. Kohler is a reminder of the hundreds of ships wrecked by storms in these waters. Nazi submarines took a heavy toll of United Nations' shipping off Hatteras. Ships hugging the coastline had to move some 10 miles out to sea to avoid shoals. Submarines laid in wait for them close in, in deep water. Survey men chart exact positions of all wrecks.
