After deducting the amount necessary for administration not exceeding 3 per cent, the remaining amount available was to be distributed as follows: “One-third in the ratio which the area of each State bears to the total area of all the States; one-third in the ratio which the population of each State bears to the total population of all the States as shown by the latest available Federal census; one-third in the ratio which the mileage of rural delivery routes and star routes in each State bears to the total mileage of rural delivery routes and star routes in all the states.” The Secretary of Agriculture is to approve only projects which are substantial in character. Items of engineering, inspection and unforeseen contingencies may not exceed 10 per cent of the estimated cost. The share paid by the Government shall not exceed 50 per cent of the total cost. The same act appropriated $10,000,000 for the survey, construction and maintenance of roads and trails within the national forests when necessary to develop the resources upon which communities within and adjacent to the national forests are dependent. The Secretary of Agriculture issued September 1, 1916, a set of rules and regulations for carrying out the Federal-Aid Road Act.[157] These are quite detailed and require a close supervision by the Office of Public Roads and Rural Engineering, the Director of which or other officers and employees designated by him, was officially appointed to represent the Secretary of Agriculture in its administration. These rules explain and relate specifically to definitions of terms; information to be furnished the Secretary; project statements; surveys, plans, specifications and estimates; project agreements; contracts; construction work and labor; records and cost keeping; payments; submission of documents to the Office of Public Roads.
