(Joi.iisnoRo, N. C. — The I.a (irange lioad was built from (Joldsboro eastward 

 toward Kingston between August 2, 1911, and September 18, 1911. The material 

 from station to station 15 was a hard gray top soil with a black loam subsoil; 

 from station 15 to station 23, sandy top soil and clay subsoil; from station 23 

 to station 46, a natural sand-clay mixture; from station 46 to station 57, clay; 

 from station 57 to station 59, sand; and from station 59 to station 73, sand with 

 clay subsoil. At station 52, 1,000 feet of road was relocated to imiuove the 

 aligumeut. The maximum cut was 18 feet, the maxinunu lill 6.5 feet, the aver- 

 age cut 0.5 foot, and the average till 0.6 foot. The grade was reduced from 7.5 

 per cent to 4.95 per cent. The total length graded was 7,300 feet, the width 30 

 feet, and the area 24.333 square yards. The surfacing material consisted of 

 natural sand or gravel clay. The length surfaced was 5,800 feet, the width 24 

 feet, and the area 15,466 square yards, of which 2,133 square yards was surfaced 

 with clay from a pit, and 13,333 square yards with clay t:'.ken from the side 

 ditches. The crown was made 0.75 inch to the foot. The excavated material 

 amounted to 5,426 cubic yards, and the following equipment was used: 1 

 road machine. 4 wheel scrapers, 11 single-horse dump carts. 4 slip scrapers, 1 

 rooter plow, 1 turning plow, and hand tools. A 30-foot span wooden bridge 20 

 feet wide was built. 



The total cost of the work was $1,199.50; the cost per square yard, $0,049; 

 and the rate per mile, $867.50. Labor was performed by convicts estimated at 

 $0.50 per day. county mules at $0.50 each, and hired mules at $1 each. The 

 principal items of cost were as follows: Excavation, $813.95; shaping the sub- 

 grade, $72.50; clearing and grubbing, $40.35; moving fences and poles, $9.20; 

 dragging, $0.95: loading clay. $30; hauling clay, $81; spreading clay, $6; and 

 maintenance of the camp, $82.05. The bridge was built by contract at an

Hickory, N. C. — A sand-clay road running southward from Hickory toward 

 Brookford was started on November 14. 1911. and completed on December 2, 

 1911. The country is hilly and the soil clay. Excavation was made by plowing, 

 and the material was moved with single-mule slip scrapers and spread with 

 shovels. The grading required no appreciable cuts or fills, and the maximum 

 grade was 5.6 per cent. One 18-inch vitrified pipe culvert. 40 feet long, was 

 laid without end walls. A plank drag was built for the work. The sand used 

 for surfacing was hauled f mile. The total length regraded was 1,050 feet, with 

 a width of 24 feet. The same length was surfaced 16 feet wide, making the 

 area surfaced 1.867 square yards. The surfacing was 6 inches thick when com- 

 pacted, and the crown IJ inches to the foot. The earth excavation amounted to 

 135 cubic yards, and the sand for surfacing, 395 cubic yards. 



The cost of the work was $198; the cost per square j'ard, $0,106; and the 

 rate per mile, $995. Labor cost $1 per day. and teams $2.50 per day. The 

 principal items of cost were: Excavation, $25.75; shaping the subgrade, $12.50; 

 labor on the culvert, $4.75; hauling the sand. $105.25; spreading the sand, 

 $17.75; mixing, $5.50; cement, $0.50; and vitrified pipe, $26. 



KiNSTON, N. C. — A sand-clay road loading westward from Kinston toward 

 La Grange, called the La Grange Road, was graded for a distance of 4,100 

 feet and surfaced 3.000 feet with a natural sand-clay mixture. The work, 

 performed by convict labor, was started on August 24. 1912. and conqileted on 

 September 28, 1912. The road was first plowed, and the material was trans- 

 ported in wheel scrapers and wagons, and spread with shovels. The average 

 cut was 0.6 foot, and the maximum grade 1 per cent. The natural soil was 

 black sandy loam unsuitable for mixing with clay. One 24-inch vitrilied-pi|)e 

 culvert 30 feet loug, a wooden bridge having .i span of 8 foot, .'ind a 20-foot 

 roadway were built. The equipment consisted of a road machine, 2 wheel 

 scrapers, 3 slat-bottom wagons, and 1 plow. The average haul was 200 feet 

 for excavation and 0.(!(> mile for surfacing material from the pit. The road 

 was graded 30 feet wide, and the area was 13,666 square yards. The width 

 Burface<l was 16 feet, and the area 5,333 square yards. 'Ihe surfacing material 

 was compacted to a deplli of (! inches, and the crown of tlie roadw.iy made 0.75 

 inch to the foot The earth excavation amounted to 699 cubic yards, and the
