8 MARKET GARDENING 



Wlicn the rows arc close together and hand work must 

 be employed, the choice of tools will largely determine the 

 cost of the cultivation. The two-wheel ami single-wheel 

 hoes are commonly used in cultivating the smaller vege- 

 table crops. The two-wheel hoe is designed and intended 

 to run straddle of the row with a wheel each side and close 

 to the plants. The various teeth and cutters furnished with 

 the double or single-wheel hoes arc adjustable so that the 

 cultivation may be ^•er^' close or farther from the plants. 

 The single-wheel hoe is designed for use between the rows. 

 There arc a number of combination seed drills and wheel hoes 

 on the market which ai'e very desirable for the small grower, 

 the cost of the combined tool being but little more than the 

 cost of the seed drill alone. The best makes of the combina- 

 tion tools allow for the elimination of the seed di'ill or wheel 

 hoe attachments as may be desired. Others make it neces- 

 sary to use both the seed drill and the wheel hoe attachments 

 at the same time; the drill simply being thrown out of gear 

 and the teeth attached.
