plates of iron inclining forward, or turned up like sleigh runners, 

 so as to prevent their clogging. The mold-board, M, and stand 

 ard between c and M, are all cast in one piece, and the edge of 

 c is cold chilled to make it wear well ; and they are bolted to the 

 wood with carriage-bolts. For preparing stiff soils for hoed crops, 

 or for any other crop, such a harrow is worth two ordinary har 

 rows. J. J. Thomas says of this harrow : " Every farmer who 

 cultivates a farm of any considerable size, especially if the soil 

 be strong and adhesive, would certainly pay for this harrow in 

 one year, by the work it would enable him to perform. Nothing 

 can exceed it in preparing inverted sod for corn, or for any other 

 crop. It is one of the best inventions of late years for the farmer."

 the centre of each collar for the tooth. Three-quarter-inch round 

 rods are used for the largest size. The frames are made in two 

 parts, hinged together as shown by the figure. The above cut 

 is a perspective view of one tooth, and the collars, or flanges, 

 as they clasp the rods. One flange is placed beneath the rods 

 and one above them, when the tooth is put in its place, and screwed 

 up firmly. 



The chief advantages of this harrow are, it is as durable as
