This simple liorse-rake has nearly gone out of use, and 

 yet, on account of its simplicity and cheapness, it is wor- 

 thy of being retained on small farms, and especially on 

 meadows with uneven surfaces. The cost need not be 

 more than three or four dollars. From twelve to fifteen 

 acres could be raked with it in a day. 



The Bevolviiig Horse-rahe (fig. 185) was next generally 

 adopted, possessing the great advantage of unloading

Revolving Horse-rake, 



"without lifting the rake or stopping the horse. It has a 

 double row of teeth, pointing each way, which are brought 

 alternately into use as the rake makes a semi-revolution 

 at each forming windrow, 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, ^he handles are 

 slightly raised, throwing this frame backwards, off the 

 points, and raising them enough for the forward row to 

 catch the earth. The continued motion of the horse 

 causes the teeth to rise and revolve, throwing the back- 

 ward teeth foremost, over the windrow. In this way, each 

 set of teeth is alternately brought into operation. The 

 cost of this rake is from $7 to $10, and twenty acres 

 or more could be raked with it in a day. 



A further improvement has been made in the revolving 

 rake, by attaching it to a sulky, on which the operator
