OUTLINE OF PLANS FOR THE CURRENT YEAR. 



The appropriation for the current fiscal year amounts to $202,120, 

 which is an increase of $41,400 over the appropriation for the year 

 1911-12. It is planned to increase the scope of the work in all of the 

 projects for which additional appropriations were provided and to 

 continue the work along other lines as heretofore. 



At its last session Congress made an appropriation of $500,000 

 to be expended for road improvement. Plans are now under way 

 for the cooperation of the Office of Public Eoads with the Post Office 

 Department to carry on this work. Under the provisions of the law 

 it is necessarv^ for the locality in which road improvement is under- 

 taken to appropriate G6f per cent of the cost of such improvement.
