on the section 5S0 foot in length settlement, caused by a center drain, had 

 iloi>re<'iated the work to some extent. Kepairs were made by building side 

 ditches from 2* to 4 feet deep on the first section, and 250 feet of the second 

 section was resurfaced by picking, cleaning, and filling depressions. After this 

 tho whole surface was treated with oil and the work was finally finished on 

 July 2(1. 1912. The following is a summary of the work done: 967 feet of 4-inch 

 tile drain laid and 3.2ij4 square yards of macadam surface treated. 



Ton cubic yards of stone filling around the drain cost $13.85; the drainpipe, 

 ?19.34; labor on the drains, etc., $113.83; cleaning the surface, $21.83; 1,500 

 gallons of crude petroleum, at 4.5 cents per gallon, including i)lacing it, amounted 

 to $08.35. The total cost of repairs was, therefore, $237.20. Labor cost $0.80, 

 $1.25. and $1.50 per day and teams $3 per day. 



The work was not finished iu a satisfactory manner on account of lack of 

 cooperation on the part of the local oflScials, 



Clarksville, Tenn.— Work on the Hopkinsville Pike, which runs north from 

 Clarksville toward Hopkinsville, Ky., was started on November 27, 1911, at 

 the stone quarry. A crusher and bin were received on December 4, 1911, and 

 excavation was begun on December 7, 1911. The work was carried on until 

 January 9. 1912, and during this time 11 days were lost on account of unfavor- 

 able weather. 



The equipment consisted of an 8 by 16 inch crusher, with a 30-ton portable 

 bin, elevator, and screen, besides plows and hand tools. The crusher had a 

 capacity of from 8 to 10 tons per hour. Nine hundred cubic yards of limestone 

 were quarried at a cost of $395, and other inoidoiital work made the total cost 

 $424.75. Labor cost $0.50 per day and teams $2.50. 



On account of the lack of preparation by the local officials and continued 

 unfavorable weather conditions, no construction work was done during the 

 period that the office was connected with it, excepting 1.075 feet of ditch, but 

 preparations were made for crushing stone, and a local engineer was employed 

 for continuing the work.
