munitions of war in the United States Under date of New York, January 16 and addressed to MT. Mix, it says:
 "Dusenberg states that it is Ital- ian about $50 Ga peculiar mark here probably means horsepower, referring to an aeroplane engine) being built to special order of government U. s. and won't say any more.
 This looks interesting No doubt you and MT B. can get the rest of the information.
 Hope to hear as to how you are progressing
 In concluding his statement Mix states that on January 20 he called on Vice President Marshall and laid full details of the transactions with Borgium before him. The following day the papers were returned to Mix win MT Marshalls assurance that he had taken the matter up with Secre- tary Baker and that it would be at tended in detail"
 Other documents dated @s far back as September If show that bQrglum at that time was working on an aero plane invention A letter from Dor glum to General Squier regarding an aeroplane brake device was also Sent to the president. in postscript longer than the original letter Bor- glum talks of two new forms of planes which he said he had per fected as to their major problems.
 q believe" he said, "and am pre- pared to make good that belief, that twenty of my battle planes, forty of my fighting planes and twenty of the smaller swift scouting machines could be built and delivered 10 the government within six months. Such fleet could deliver 100000 pounds of high explosives on either Zee brugge or Helgoland or Kiel canal nightly for week without especial danger to itself l will go further will, if the government will order such fleet, agree to deliver such a fleet a thousand miles by continuous High. from the base of manufacture, 1e ready for duty and provide bonds for the faithful performance of all agreements"
 This project was offered before Borgum had interested himself i'll the activities of the signal corps and the air board. and he describes his machines as tube planes Appar- eLtly all of the correspondence was sent to the signal corps and the pro feet was turned down. it is said, by Colonel Deeds
 In transmitting the letter to the president, Horalum took occasion to object to the adoption of "the clumsy unman9gatle tri-pDune," which he said was being vigorously exploited.
 Presumably this referred to the Italian Caproui which was being ex- hibited about that time. In a letter tC Secretary Baker on the same sub ioct Borglum said he desired to do what ! can at this time to stop the United States from buying or order ing the numbering, uncomfortable eeroplanes of the Italians"
 "We can do better" he wrote. "in- fants though we are-l want to pro test against any great outlay of money for the Italian planes if we can create a better, more efficient. safer instrument to do the same they propose
 In August Borglum wrote Prof. w. F. Durand chairman of the national aeronautic committee regarding tests of certain models which we had sought to have made at the Massa chusetts institute of technology His original models were too large for the wind tunnel. the letter shows. and it had made smaller models
 A message from NJ. C. Peabody dated May 3, 1918, is attached show
 ing that these smaller models never were submitted al the institute for test,
