to be superior to all others. The advantage of this lies in the 



form of the colters, which 

 are broad thin blades of cast- 

 iron ; or, what is far better, 

 of steel, because lighter, less

 to wear dull. These teeth, 

 or colters, incline forward, 

 which prevents clogging with 

 grass roots, stones, or clods. 

 There is a mouldboard at-

 made seven feet long, and 

 weighs about one hundred

 very effectively, pass over 

 and press down the sod, 

 while, at the same time, shaving off and grinding up finely the 

 upper surface. A single passage of this implement will mellow 

 the surface more than twice as deeply as the ordinary harrow ;

The same firm manufacture, also, an Improved Horse Hoe. 

 By a simple change in the arrangement of the teeth or colters 

 it is admirably adapted to the cultivation and hoeing of most 

 kinds of crops, while the high standards prevent the liability to
