Road dragging {Mo. Bui. ifissouri St<ne Bd. Agr., 3 {1903), No. 1, pp. 42, figs. 7). — 

 This Ijulletin discusses the method of road dragging proposed and successfully prac- 

 ticed by D. W. King, of Maitland, IMo. The construction and use of the" road drag 

 is thus described: "The drag is made by splitting a log, placing the two pieces about 

 30 in. apart (with the flat sides both facing in the same direction), and pinning them 

 togetlier. The lower edge of the front piece is protected with iron; an old wagon 

 tire will do. The log should be 10 or 12 in. thick and about 10 ft. long. Fasten a 

 chain or heavy wire a foot or 18 in. from each end by which to haul it. Hitch the 

 team so the drag will move the dirt toward the center of the road. The hitch is 

 next in importance to the time at which the dragging is done. The right time is 

 just as the road dries after a rain or when it is thawed on top during the winter and 

 spring, and it should be dragged every time." 



The bulletin also contains articles on The Best Application of Our Road Laws, by 



G. AY. Waters, and The General Interest of the United States Government in the 

 Improvement of Public Roads, by W. R. Richardson.
