870 ANNUAL BEPORTS OF DEPARTMENT OP AGRICULTURE. 



to the earth road, with burnt clay at a considerable advance in cost, and with 

 ordinary macadam surfacing. It was suRgested that in view of the fact that 

 many miles of road still remained to be hiillt in the county, experiments be 

 made, with each of the various classes of surfacing recommended, on the road 

 from England to district No. 4 in Pulaski County. Special emphasis was laid 

 In the engineer's report concerning maintenance and the use of the road drag. 



Walton County, Fla. — Work in this county during October, 1911, was for 

 the purpose of investigating conditions in connection with the use of a bond 

 issue for $70,tK)0 for the particular road district which contains the county 

 Beat, De Funiak Springs. 



The proposed system involves approximately 60 miles of road, 34 miles of 

 which is the central county road, and the remaining 25 miles are lateral roads 

 extending north and south from the principal railroad points to the district 

 line. 



A study was made of existing conditions and road materials. Clay and sand 

 deposits were located, and also some fine gravel. The road location and the 

 right-of-way width were determined by law. Recommendations covering clear- 

 ing of the right of way, grading the width of traveled way, and other details 

 were supplied. Specific information for surfacing with sand-clay was sub- 

 mitted, together with specifications for culverts, etc. 



Pulaski County, Ga. — An engineer from this office made an investigation in 

 Pulaski County during May, 1912. This county covers an approximate area of 

 463 square miles and has about 373 miles of public roads. About 113 miles of 

 this system sustain the largest amount of the traflic. The soil is generally 

 sand or clay, or a mixture of both. There are limited deposits of gravel. Con- 

 ditions are favorable for the construction of siind-clay roads, as the materials 

 will not be hauled for more than a mile, and frequently are to be found along 

 the road. There is stone suitable for concrete use in nearly every creek. The 

 present condition of the roads was studied, particularly with reference to drain- 

 age and grades. 



The county's finances were investigated, and a table prepared showing the dis- 

 tribution of property and road mileage. A study was made of the present 

 road law and i-ecommendations were submitted for its improvement. A general 

 system for improving the roads of the county was developed and detailed infor- 

 mation was supplied for the three natural subdivisions of the county. The 

 estimated cost of constructing eight sections, aggregating approximately 35 miles, 

 was supplied, together with specifications and detailed plans for earth and sand- 

 clay surfacing, culverts, end walls, etc. 



The report submitted gave special attention to the financing and management; 

 of future maintenance operations under the improved road system. 



St. Joseph County, Ind. — During the interval from May 27 to June 15, 1912, 

 an iasi)ection of about 300 miles of road leading in various directions from 

 South Bend was made by an engineer from this office. The general condition 

 of the roads was observed and the location of gravel deix)sits and other road 

 materials investigated. As a result of the study it was recommended that the 

 less important roads be built with gravel and that concrete be used for those 

 of more importance. An excellent quality of sand and gravel is present for use 

 in concrete work. 



The roads under consideration for improvement were the Goppart Road, con- 

 sisting of six separate sections leading from the town of Walkerton, a total of 

 78,862 feet; the Whittmer Road, near South Bend, 15,000 feet; the Markham 

 Road, near South Bend, 15,800 feet ; and the Leach Road, also near South Bend, 

 15.800 feet. Sjiecifications for the construction of the first two of the above 

 roads were supplied. It was proposed to build the last-mentioned roads of 

 crushed bowlders, but specifications were prepared for constructing them with 

 concrete. 



Estimates and recommendations were developed with the cooperation of the 

 county engineer. It is expected that other roads will be considered for con- 

 struction in the future. 



Noxubee County, Miss. — Supervisor's district No. 1. — During March, 1912, 

 an investigation for the construction of two permanent highways was made by 

 an engineer from this office. These roads require financing by bond issue, 

 and may be regarded as the beginning of systematic road improvement in this 

 district. A report was made by the engineer showing the existing conditions of
