Barrett has been for some time carrying on cooper-\native experiments regarding aiming sticks. The adoption of the aiming stick\nwould alone run into several hundred thousand dollars worth of business.\nNAVAL GUN FACTORY, WASHINGTON NAVY YARD, WASHINGTON, D. C.\nCommunica' ions should be addressed to Superintendent and\nCommandant, Naval Gun Factory, Washington, D. C. (A. W. Grant) Personal\ninterviews with department heads should commence with Senior Inspector, who\nwill refer to various department heads.\nThe Navy Department is working to adopt luminous degree marks\nand numerale on various instruments, also luminous sights. They are proceeding\nwith the matter very slowly and no immediate volume of businese can be expected\nfrom them. At present they are very much sold on the idea of using luminous\nmaterial sealed in short glass tubes. The rounded end of this tube being used\nas a lense and the tip being sunk into a metal plate. The tube for the even\n10\ndegrees is somewhat larger. Request for 250 small and 50 large tubes in\nconnection with this idea was received by us January 12th. This work comes under\nthe direction of Lieut. Commander Seed, Washington Navy Yard.\nThe two civilians who are actually carrying on the mental\neffort in this matter are: G. A. Luers, Drafting Room and R. M. Critchfield,\nDrafting Room. G. A. Luers seems very much set upon radium content as a guide\nin drawing specifications. He seems inspired upon this point. Mr. Critchfield\nis amenable to argument in this matter.\nTo secure Navy waterial for experimental sample work, etc.\nthe order must come from Lieut. Com. Reichmuth, Bureau of Ordnance.\nLieut.

He is not, however, in\ncharge of drawing these specifications, and introduced me to L. P.

P. Hart, (Telephone Main 2790, Branch 859) in charge\nof this, is technically trained but desirous of drawing specifications which will\nallow the Government to purchase suitable luminous material at a price not out of\nproportion to its actual value.
