 intended to be used where the growth of grass is ver\' rank. It was originall}^ 

 designed to be used \\ith the hona-hona {Comtnelina nudiftora) grass of the

 the soil along with the cane trash.

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

 knives revolve and break up and pulverize the soil.

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

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