Calculation of the labor-saving properties of the Tnachine. 

 One acre of ground is 160 rods, or one-half mile long, and 16§ 

 feet, or one rod wide. Man and team travels, 



_ Miles.

To put in an acre with the machine four feet wide, in the most 

 perfect manner, the farmer has, in addition to the other advan- 

 tages, no labor to perform but driving, and the team travels but 

 2yV miles ; with a six foot machine, one and two-fifths of a mile. 

 So if the team can travel 18 miles a day, the farmer can put in 

 8| acres per day; with a six foot machine and three horses 13^
