Missouri Agricultural Report. 



The fourth one-fourth of the mile was a long 4 per cent grade with 

 a genuine hard-pan and chert soil. It was not difficult to work, for while 

 hard to plow, only requiring power, it contained few large rocks or 

 boulders, and after loosening with the rooter, was easily handled with the 

 graders. 



We found that the county highway engineer here, alive to the situ- 

 ation and determined to make the most ofo\ir short stay, had employed 

 an additional traction engine and twenty gravel teams and wagons. The 

 entire mile was staked out 20 feet between centers of ditches. The first 

 one-half mile was graded, crowned, ditched, shaped and rolled complete. 

 The first one-fourth mile was then graveled with an 8-foot center strip of 

 gravel, shouldered and rolled down. The gravel was put on 10 inches 

 thick, loose, on the fills (of which there were two short ones), and 4 

 inches thick over the chert soil foundation. Some of this chert soil would 

 not need surfacing, but the soil was of a coarse, rough formation and the 

 gravel was fine enough to give it a smooth surface.

The second one-half mile of the one mile selected, owing to the rain 

 on Friday morning, the bog holes, loads of boulders and the corduroy, 

 was ditched and partially shaped and crowned, but left in an unfinished 

 condition from a lack of time. A 40-inch circular concrete culvert 17 

 feet long with head walls was also constructed. The interest shown here 

 was as intense as in any place on the trip. The total attendance on the 

 work was about 200, but it was sincere. About 70 attended the road 

 meeting and lecture on the last evening in Marshfield. 



Rain so interfered at Republic that practically nothing was at-
