potash, or ashes, should be spread on the surface, be* 

 cause such heavy fertilizing material has a tendency to 

 work downward into the soil. The main point, in my 

 own estimation is, to make rich manure, and cover 

 it with a thin dressing of soil. J. Harris says, &quot; There, 

 is not enough ammonia in a ton of such stuff as many 

 farmers call manure, to make hartshorn enough for a 

 lady s smelling- bottle ! ! ! Instead of ploughing in so 

 much clover for wheat, then, let us convert it into wool 

 and mutton ; and if we can give our sheep peas, or 

 beans, or oilcake in addition, it will tell wonderfully on 

 the manure, and on the crops to which it is applied.&quot; 



The illustration herewith given represents a new and 

 eminently useful coulter, to prevent clogging when 

 ploughing stubble ground, or when turning under 

 coarse manure or 

 clover invented by 

 M. A. Spink, Rensse- 

 laer Falls, New York, 

 and sold also by R. 

 H. Allen & Co., 189 

 Water street, New 

 York city. It can be 

 readily attached to 

 the beam of almost 

 any plough, with the 

 same fastening that 

 is required to secure 

 an ordinary coulter 

 in the desired posi 

 tion. The shank of the coulter should stand perpen 

 dicularly on the beam of the plough, as represented by 

 the illustration. The upper part of the blade is made as
