WiN'cuESTER, Tenn.— The work of improving the Winchester-Decherd road at

 The improvement consisted of opening 9,000 lineal feet of new road, grading it to the 

 width of 28 feet from edge to edge of the shoulders, surfacing it 16 feet in width, and 

 constructing cross drains of corrugated ingot iron as follows: One 28 feet long and 20

 18 inches in diameter, three 26 feet long and 18 inches in diameter, and one 46 feet 

 long and 12 inches in diameter. The grading required the moving of 9,749 cubic

 course, 2 inches thick, measured loose, was from one-half inch to 1^ inches in size; 

 and the third course, screenings smaller than one-half inch, was applied in sufficient 

 quantity to bond the road, that is, to a depth of about 1 inch. Water for the roller

Provo, Utah.— a macadam road 2,850 feet in length and 15 feet in width was con- 

 structed at Provo, Utah, between October 25, 1909, and December 24, 1909. It was 

 a part of a proposed improved road extending from the city of Provo to Provo Canyon, a 

 distance of 6 miles. During this time eight and one-half days were lost on account of 

 rain and snow. The immediate surrounding country is practically level. The soil 

 over which the road was built is adobe, which, when wet, has very little ability to 

 support a load. In winter the road was practically impassable. At the north end of 

 the road it was necessary to make a hillside cut in a hill composed principally of rocks 

 of quartzite varving in size from 2 to 12 inches in diameter, and on account of a large 

 irrigation ditch "running along the foot of the hill it was not practicable to push the
