dated Washington, February 5, 1914, I proceeded to Vienna on February 19th, remaining in that vicinity for one week. The main purpose in making this trip was to obtain first hand information in regard to the "arrow type" Lohner biplane. In addition to this type they also manufacture a monoplane similar to the Etrich. Due to the fact that the monoplane has not proved so successful as the biplane, it is gradually being eliminated. A complete description of the various types manufactured in Austria is on file in the office of the Chief Signal Officers of the Army.

A full description and sketch are contained in the file mentioned above. Great care is taken to bore as few holes as possible in the main spars. All spar fittings are large, ,going completely around the spar. Wing construction, good. Irish linen is used for covering. The covering of the motor wing section is treated with a fire-proof compound. Strong and pliable cable is used for control wires. The Deperdussin type of control is employed, but instead of a rudder foot-bar, two pedals are used. The machines are equipped with both the Hiero and Austro-Daimler motors.
