implement of entirely new character, and rendered capable of 

 very desirable preparation of the gronnd l)y deep woriting. The 

 additions are very readily ap})lied when the transformation is 

 reqnired, and as easily laid aside again Avhen it is wanted for 

 ordinary work without impairing in any degree its utility or con- 

 venience. 



Fig. 2 represents the most important of the additions for the 

 transformation to which all of the others are accessory or sup- 

 plemental. This consists chiefly of an inclined 

 plane or share, either in one or more pieces, as 

 circumstances may determine. This arrangement 

 has a corresponding land side, to Avhich the 

 original gives place in transformation. There are 

 two sizes of the inclined plane, designated as No. 1 and No. 2. 

 The latter is able to raise its slice of suljsoil from the greater 

 depth. Each size of the inclined planes has a corresponding 

 accessory part for rendering them more efficient for certain pur- 

 poses that will be noted in the account of the operation of the 

 implement. There are also two supplementary pieces for increas- 

 ing the width of the mould-board at its upper edge, the wider of 

 which is used for the deeper working.

Fig. 3 represents the most simple form of the Transformed No. 

 1, having the narrow supplemental plate and the No. 1 inclined 

 plane without any of the accessories, all of which are important 

 in fitting it for the variety of uses to which it is adapted. These 

 are of the utmost simplicity in their manner of application, are 

 durable in wear, and not liable to break or get out of repair. 

 These plows perform easily and thoroughly the operation of 

 trench plowing, that is often attemvjted Hjut always with a very
