 The two parts of the roller should be one inch and a half apart, 

 as at the dotted lines, and should run as close to the hind girt as 

 practicable, in order to scrape off any dirt that may adhere to it. 

 But soil should never be rolled when it is wet enough to stick to

 thirty-six cents, eight carriage-bolts fifty cents, for bolting-tongue 

 and bearing-boxes, and two and a half days' work, $3 13. Rec- 

 oning the timber at one cent per foot, the cost of a good roller 

 will not exceed 192 + 192 + 50 + 27 + 10 + 30 + 36 + 50 + $3 13
