“ The expression by a witness, or witnesses, of the opinion that the person for whom an award is sought acted with extreme daring and endangered his life is not sufficient basis for an award, but the affidavits or testimony should set forth the pertinent facts in detail, and show clearly in what manner and to what extent the life of the applicant was endangered and extreme daring manifested by him. ”

“ The Commission, or the committee with the approval of the Commission, may direct any inspector in the employ of the Commission to proceed to the locality where the act or acts in question were performed and to make a personal investigation of the matter, and to make a report upon the facts of the case. Such report shall be filed and shall be made a part of the evidence to be considered. In any case in which the Commission recommends that an award be made posthumously, its recommendation shall designate the relative or other person to whom the medal should be presented. ”

“ Applications should be addressed to and filed with the Interstate Commerce Commission, Washington, D.C. The acts relied upon in the application must be of such a nature that the applicant would not be expected or required to perform such acts in performing the duties of his regular work or vocation. Satisfactory evidence of the facts upon which the application is based must be filed in each case. Such evidence should be in the form of affidavits made by witnesses of good repute and standing, testifying of their own knowledge. ”
