THE GENESEE FAEMER. 



SMITH S WEB-HAEROW. 



SMITH'S WEB-HAKROW. 



"We annex an engraving of an ingenious harrow 

 invented by the late Mr. Smith, of Deanston, Eng- 

 land. It is designed to cover small seeds ; the aim 

 being to combine the operations of the roller and 

 harrow. It is called the web-harrow, and was 

 alluded to in the last volume of the Genesee Farmer. 

 "We have now the pleasure of presenting a cut of it. 

 It consists of an iron chain web, connected by discs 

 or quoits of iron which, lying obliquely upon their 

 sides when in operation, roll around, thus tearing 

 and abraiding the surface of the ground, and grind- 



ing the smaller clods, so as to expose and dis^ 

 the surface sufficiently to cover the small s( 

 strewn upon it. The serrated form of the dis 

 shown at a in the accompanying figure, where 

 mode in which these dies bind the whole fra 

 work together is also exhibited at 5. It is by 

 rubbing of the sides of the discs against the 1 

 as they revolve, that they are especially us 

 more than by the action of their edges, the 

 that is also efficient to some extent. Tke j 

 of this harrow in England is about $25, cove 

 25 square feet of ground.

PLOWS FOR CirmNG TTNDERDRAINS. 



It is frequently the practice, in cutting under- 

 drains, to throw out the first eight or ten inches 

 of earth by means of the common plow. The 

 accompanying figure, taken from Morton's CpcJo- 

 pedia of Agriculture represents a plow sometimes 

 iippf? ^v Scotland for throwing out a lower spit. 



In addition to the ordinary coulter, it also cai 

 another, c, supported by two iron arms attache 

 the beam at a and 3. By means of the two cou 

 and the shoveled-shaped mouth, or share, a fai 

 slice is at once cut out the width of the drain, 

 ten to twelve inches deep. The vertical rollc 

 preserves the position of the implement in I
