ApTproximate cost per rod of digging ditch, laying tile, and blinding under conditions named 



above. 



Where the ground is so hard as to require a considerable use of the 

 pick or bar the cost may reach double that indicated in the table. 



The filling of a three-foot ditch will cost three cents per rod where 

 a team and plow or scraper are used, or six cents per rod when done 

 by hand labor. The cost of filling other sizes of ditch will vary from 

 these figures according to the depth and width of the ditch, and will be 

 about proportional to the cross section of the ditch. 



In Lenawee County, Mich., a common practice is to charge by the foot 

 for digging the ditch and laying the tile. When the drains average 

 3 ft. deep the price is IV2 cents per foot for laying different sizes up to 

 and including 4-inch tile, while the price is 2 cents per foot for 5 and 

 G-inch tile. Above 6-inch tile, wages are usually paid by the day.
