 each way, wliich are brought alternately into use as 

 the rake makes a semi-revolution at each forming win- 

 row in its onward progress. They are kept flat upon 

 the ground by the pressure of the square frame on their 

 points beneath the handles ; but as soon as a load of 

 hay has collected, the handles are slightly raised, throw-
