face. The draught of this plow is easy, and in light and 

 medium soils it leaves the surface eyen and mellow. Being 

 short on the sole it is well adapted to stony land. It is remark- 

 ably evenly balanced, and in stubble land it scarcely requires 

 holdino-. This shows the plow to be made on true mechanical 

 principles. 



A plow has been constructed for the purpose of opening 

 drills to plant corn or potatoes, and for ridging up for certain 

 kinds of vegetables or root-crops. {Fig. 31.) It is a double 

 mould-board, as shown in the foregoing cut, and throws the 

 furrow out both ways. It has often been found convenient in 

 digging potatoes. 



A plow is often required for side hills, or rough and un- 

 even land where the ordinary plow cannot readily be worked. 



"What is called the Swivel plow, {jig. 32,) is used for this 

 purpose, the mould-board being constructed double, and so as to 

 revolve from one side of the standard and beam to the other, 

 making a right or left hand plow at pleasure, while the team is 

 in the act of turning at the end of the land. The hook being 

 lifted it turns of itself, or with only a slight efibrt, from one 

 side to the other. The plowman may begin on the lower edge 

 of a side hill, and turn his furrows all down the slope, or he 

 may begin on one side of a level field, and lay his furrows all 

 one way, and so avoid the dead furrow in the centre and the 

 ridging on the sides. Now that the mowing machine has be- 

 come so universal, it is quite important to keep the land level, 

 and hence the Swivel plow is coming into general use upon 

 well managed farms. 



This plough, manufactured by the Ames Plow Company of 

 Boston, received the medal, or highest premium, of the Ne«r 

 England Agricultural Society, at the great plow trial at Am 

 herst, in 1868.
