AMERICAN GARDENER. $5 



^found, or placed, beyond the end of the 

 work, and should have directed the head of 

 the ox in a line with those two objects. Before I 

 started, I should have measured off the width to 

 find where the ox ought to come to again, and 

 then have fixed two objects to direct his coming 

 back. I should have done this at each end, till 

 the piece had been finished. 



166. But, is there no other use, to which this 

 roller could be put ? Have I not seen, in the 

 marking of a corn-field, a man (nay the farmer 

 himself) mounted upon ahorse, which dragged a 

 log- of wood after it, m order to indicate the lines 

 upon which the corn was to be planted ? And 

 have I not, at other times, seen the farmer making 

 these marks, one at a time, with a filough ? And 

 have I not seen the beauty of these most beautiful 

 scenes of vegetation marred by the crookedness 

 of the lines thus drawn ? Now, take my roller, 

 take all the teeth out but three, let these three be 

 at four feet apart. Begin well on one side of the 

 field ; mount your horse ; load the teeth well with 

 a stone tied on each ; drop the bar ; take two 

 objects in your eye ; go on, keep the two objects 

 in line, and you draw three lines at once, all 

 straight and parallel, even if a mile long. Then, 

 turn, and carefully fix the horse again, so that 

 you leave four feet between the outside line drawn 

 before and the inside tooth. You have already 

 measured at the other end (where you started,) 

 and have placed two objects for your guide. Go 

 on, keeping these objects in aline; and you have 

 three more lines. Thus you proceed till the field 

 be finished. Here is a great saving of time ; but, 

 were it for nothing but the look, ought not the log 

 to give place to the roller ?
