The steam traction engine costs $1,500, while the Monroe lev- 

 eller and engine costs $3,200. The Monroe leveller is a form of 

 road drag or grader which covers the entire roadway from ditch 

 to ditch. Its field is the earth road, which must be graded to a 

 good crown prior to use of leveller and the surface of the road 

 must be practically free from vegetation, especially sod. The road 

 should also be practically free of rocks. The machine and engine 

 each cover a width of 12 feet, so that all culverts and bridges must 

 have at least a width of 12 feet to allow crossing. The machine 

 is so constructed that the grading blades may be drawn in, thus 

 permitting the machine to pass over bridges and culverts, and also 

 permitting its use on roads of less width than the maximum draft 

 of the machine.
