THE HUSBANDRY OF THE CANE 



123 



hilling up rows of cane (Fig. 34) the revolving knives and discs alone are 

 used, the subsoiler being detached. 



In Fig. 37 is shown the Horner combined weeder, cultivator and harrow, 

 intended to be used where the growth of grass is very rank. It was originally 

 designed to be used with the hona-hona (Commelina nudiflora) grass of the 

 Hawaiian Islands ; the semicircular teeth tear up the weeds and at the same 

 time cultivate the soil. The load of weeds gathered in the cradle can be 

 discharged by lifting up the handles of the implement. 



Spaulding Deep-tilling Plough. This implement (Plate XIV) is used;"to 

 an increasing extent in the Hawaiian Islands in turning under cane trash. 

 In operation the front disc takes off a slice of soil, turning it into the bottom

of the previous furrow. The second disc operating about four inches inside 

 the track of the other on a space cleared of cane stumps and grass by the 

 first disc has no difficulty in effectively turning over and burying a slice of 

 the soil along with the cane trash. 



Stubble Digger. This implement, Fig. 38, is mainly confined to Louisiana- 

 It consists of a rotary shaft, on which are fitted blades, arranged about a 

 helix. When the carriage is drawn along the rows of ratoon cane, the 

 knives revolve and break up and pulverize the soil. 



Stubble Shaver. This instrument, Fig. 39, the use of which is also con- 

 fined to Louisiana, is used to cut down cane stumps flush with the ground. 

 Its essential mechanism is a horizontal circular knife, which rotates as the 

 carriage is drawn along.
