IN ORDER successfully to fulfill its mission in time of war, the Navy must thoroughly organize and prepare itself in time of peace. Preparedness is the keynote of its success and no part of the complicated naval structure can be neglected without detrimental effect upon the whole. In line with this preparation great sums of money have been expended in building, equipping and operating navy yards, fueling stations, radio stations, etc. This vast expenditure has been made primarily for the purpose of affording every facility for maintaining the efficiency of the fighting fleet in time of war. War preparedness is the only possible justification for these large expenditures. In peace times the functions of these establishments could be as economically performed through the ordinary commercial agencies, but in order to insure that the Navy will have available and under its control the facilities necessary for its operation when the emergency arises, these expenditures are authorized from year to year and there can be no question as to the wisdom of such a course.
