by long stirrups made from % round iron. These are 

 counedled with a tilting lever so as to raise them in

 the frame and the team is attached to a strong pole. 

 The advantage of this machine is that it firms the seed- 

 bed and at the same time makes small furrows for the 

 irrigating water. This prevents flooding and baking, 

 and permits the water to seep through from one corru- 

 gate to the other without injuring the surface. In a 

 meadow these corrugations will remain for years and 

 do not interfere with harvesting machines.
