1 Hatchways in this will communicate with the cars of the ship, which will be slung below the body, while verti- cal shafts provided with ladders rise from the passage through the body to the "cat-walk" on top, providing i means of communication between the top and bottom.
 Complex Controls Along the side of the corridor runs mass of piano-wire controls, passing over multitude of pulleys and con- meeting with the hundreds of valves, signals and pieces of apparatus throughout the ship.
 slung from the girders forming the corridor are the water ballast bags, each holding nearly ton of water, used for trimming the ship, with great valves at the bottom that can empty them almost in an instant if the ship has to rise quickly.
 | side of the corridor at various points. And here is where provision has been made against the fire danger that has cost so many lives in the past.
 The tanks of the ZR-1 are set in vertical slides and locked into posi- tion. If fire breaks out and they are threatened or if a squadron of at tacking airplanes should make it inn perative to shoot up to lofty altl- tude, a simple pull of control wire releases them and they fall earthWard. relieving the ship of their great weight and the menace of gasoline ex- plosiOn.
 To Use Helium
 The fire danger will also be met in the new ship by the use of helium gas on test flights, 100000 cubic feet, practically all available in this coun- try, being required. As an added safe ty measure the external skin, or fabric covering over the framework of the hull, will have a heatdefying cloth in- side while the outside will be "doped" with aluminium to reflect the rays of the sun, thereby minimizing the ex- pansion of the gas inside the ship.
 The "brains" of the airship will center in the control car slung under the bows. This will contain all the mechanism for the operation of the various parts and also the radio appa- ratus. The rear of the car will hold 30O-horsepower. six-cylinder Packard motor. Five other motors are provid- will be placed two and two on either side of the ship some distance behind the control car, the last one central ly under the tail. Two of the cars will have reversing propellers for manoeuvrng.
 The armament of the ZR-1 will comprise eight machine-guns in the various cars, providing an alEaround field of fire, and a two-pounder, high angle gun mounted on the observation platform on top of the ship for sweep ing the skies above.
 Track for Landing
 Arrangements for docking are two fold. For housing in the hangar spe- cial tracks have been laid upon which trolleys will run out of the shed. The ship, alighting outside the hangar, will be made fast to the trolleys and then slowly hauled in.
 But some distance away over the level sandy tract of the air station is another means of anchorage that sym bolizes the future when vast airports in every country will swarm with ships of the air. Rising 16S feet above the plain is a giant mooring mast for the ZR-1, to which the nose" of the airship can be made fast, allowing it to float in the air Hike a flag" as Commander Weyer- bacher expresses it.
 A doorway in the nose" of the ship will provide a means of entrance and exit for officers and crew, while pipes running up the tower from the ground will connect with openings in the bow of the airship through which
