The operating expense of the Monroe leveller outfit is $9.00 

 per day. This figure includes gasoline, lubricant and hire of two 

 men, one to operate the leveller and the other to run the engine. 

 It is claimed by the manufacturers that 15 to 20 miles of road can 

 be traversed per day one way, and that once going over the road 

 is sufficient to put it in first-class condition. This assumes the 

 road to be in ideal condition, for work. It is our opinion, however, 

 that one round will be necessary on most roads to give satisfactory 

 results. Admitting that 20 miles can be traversed per day, and 

 that one round is necessary to put the road in prime condition, a 

 length of 10 miles of road can be graded per day. The cost will 

 therefore be 90 cents per mile. 



Hannibal and Palmyra macadam road, Marion county. 



At the present time a macadam road is under construction be-

 of the road has been constructed. The work of construction is still 

 going on, but it is not expected that the road will be completed be- 

 fore the summer of 1913. The rocking of the road is being done 

 under a contract of $1.25 per cubic yard in the finished road, the 

 county furnishing the crushing and quarrying equipmen.t, consist-
