Within a reasonable time after the effective date of said notice, in no event less than ten days, the head of the department or agency of the Government concerned, shall by order fix and specify such rates or amounts of royalties, if any, as he shall determine are fair and just, taking into account the conditions of wartime production, and shall authorize the payment thereof by the licensee to the licensor on account of such manufacture, use, sale, or other disposition: Pro- vided, however, That the licensee or licensor, if he so requests within ten days from and after the effective date of said notice, may within thirty days from the date of such request present in writing or in co any facts or circumstances which may, in his opinion, have a earing upon the rates or amounts of royalties, if any, to be deter- mined, fixed and specified as aforesaid, and any order fixing and specifying the rates and amounts of royalties shall be issued within a reasonable time after such presentation.
