POTATO CULTUBE. 



The wheels and irons they run on, doubletree, whiffletrees, 

 and draft-irons, are taken from a two-horse sulky cultivator, 

 and the spring seat from the Eureka mower. All the joints 

 in the frame are simply bolted together, which makes it 

 quite cheap. 



FIG. 6. SECTION OF ROW. 



The two marks, when made, look about like Fig. 6. After 

 the potatoes are dropped, all that is necessary to cover them 

 nicely is to level down the center-ridge X. A light scraper,

shown in Fig. 7, does this perfectly. Use doubletrees and 

 neck-yoke twice as long as the width between two rows; 

 the horses then walk between the rows (at P, P, Fig. 6), arid 

 not on the potatoes. The other pair of handles, sawed off 

 from the plows, are put on the scraper as shown at N. The 

 plank O, for rows 32 inches apart, should be about 64 inches 

 long; and 20 inches is about the right width. The pole 

 should be at right angles with the plank, both up and down 

 and sidewise. This plank should be of light wood, as it is 

 easier to bear down to make it take more earth, if it is too 

 light, than to lift up to make it take less, if it is too heavy. 

 The front bottom edge should have a piece of band iron 

 fastened on, projecting down a little below the wood. This 

 scraper carries a quantity of earth ahead of it all the time,
