THE WORK THICKENS. 55 



For the earlier cultivatings we want one or the other of 

 tliese double-wheel hoes. They straddle the row, and allow 

 the operator to direct all his attention upon a single row. 

 The single-wheel hoes, among them the Planet, Jr., and 

 Ruhlman's, which latter is also a serviceable implement, 

 come handy after the onions are half grown. 



No man can hope to be successful in commercial onion- 

 growing without being well equipped with these imple- 

 ments, or without using them, less as weed slayers, as they 

 have sometimes been called, but rather as preventives 

 against Aveeds.

 days after the seed is sown by the old method, or imme-

 the wheel hoe should be started. Do the work thoroughly, 

 letting the cutting blades go as close to the rows as is safe,
