 Virginia, the Coast Artillery Board tests the wire thrower RL37 T2. It is designed to carry a standard one-mile reel of field wire, W110 or W110B by a single cylinder five horsepower gasoline engine, the trajectory of the wire during the wire laying operation. The wire thrower can project wire to a height of 40 feet and as far as 75 feet on either side of the wire laying truck, choose to recover wire at any speed up to 10 miles per hour. One twisted pair of field wires may be recovered from the rear or from either side of the vehicle. Hand wheel controls the reel feeding mechanism. This machine weighs approximately 600 pounds without the reel. In the United States Army's standard flat top camouflage net is being erected. A wire framework is first constructed, wooden posts being used as supports. The rope net is carefully folded preparatory to being placed on the framework then placed on top of the framework. Funds about five feet long are painted to match the various colors of the surrounding terrain. These are woven into the net with a length of about two feet hanging down on each end. Note the appearance from above. Here is provided at one point in the net. This embrasure is opened as shown here when an artillery piece is to be fired. Belvoir an experimental tilt type semi-trailer is demonstrated. It is designed for transportation of a medium tractor. The truck which furnishes the motive power for the trailer is of standard type. Wooden blocks are used here only because this particular tractor is somewhat defective and its tracks cannot catch the rear end of the trailer. Normally blocks are unnecessary. The operator loosens the load binder cables which are fastened to a ratchet pulley.
