Contract No. 4, Bradley Lane, Md. — Work was begun August 4, 1913, 

 on the section of road extending from Wisconsin Avenue toward Connecticut 

 Avenue on Bradley Lane. It was completed September 30, 1913. The road 

 was graded 16 feet in both cuts and fills for 1,530 feet. A surface of macadam 

 was laid for 1,530 feet, 10 feet wide, making 1,700 square yards. The crushed 

 rock was delivered on the cars and hauled to the road, with an average haul 

 of three-eighths mile. The surface of the old macadam road was loosened 

 with spikes in the roller wheels, and torn apart with a 3-ton scarifier. This 

 surface was then reshaped and leveled with No. 1 stone, and rolled, after 

 which 3 inches of No. 2 stone were spread and rolled. About 1 inch of binder 

 course was then spread, watered, and rolled, and the road finished with a crown 

 of one-half inch to the foot. 



The road was built by contract for $1,285.72, which is at the rate of $0,756 

 per square yard. Labor cost $1.70 and teams $4.50 per day of eight hours. 



POST-ROAD WORK. 



Under the act of Congress of August 24, 1912, making appropria- 

 tion for the Post Office Department for the fiscal year 1913, there 

 was appropriated $500,000 for the improvement of roads used in 

 rural delivery, in order to ascertain how such improvement would 

 affect the amount of territory served by rural carriers, the increase 

 in number of delivery days, etc. In short, the improvements were 

 to be carried out in such manner as to indicate the relative saving to 

 the Government in the operation of the Rural Delivery Service, and 

 to the local inhabitants in the transportation of their products. 

 The Secretary of Agriculture was appointed to cooperate with the 

 Postmaster General and to furnish the supervision for the construc- 

 tion work, which is being done through the Office of Public Roads. 

 Under the act the local authorities pay not less than two-thirds of 

 the cost of the improvement, and the Federal Government the re- 

 maining one-third. A detailed report, containing description and 

 cost data of the work, will be published in a joint report made to 

 Congress by the Secretary of Agriculture and the Postmaster Gen- 

 eral upon the completion of the work, which comprises the following
