tlio slieatli immediately above the mold-board, aud connected only at 

 the point of the beam by a rod moving in a rabbet. This arrangement, 

 while it ])laccs the point of dranght immediately at the work, relieves 

 the beam from the danger of strain and consequent displacement, so 

 destructive of the whole implement. Plows are distinguished by being 

 cither right or left handed; that is, throwing the furrow to the right or 

 left side. The use of either is cotamon to particular localities ; in some, 

 such a thing as a right-hand plow is not to be found, while in others a 

 left-hand plow is scarcely known. But it may be remarked that Whore 

 the left-hand plow is used the team is almost invariably driven with a 

 single line, and that of a right-hand plow with a double lice ; and fot the 

 reason— and it is one of the advantages claimed for the left-hand plow- 

 that the lead-horse walks in the furrow, and consequently requires less 

 guiding and less skill in the plowman. There is, perhaps, no implement 

 of husbandry which has undergone so many changes and so many im-* 

 provements as the plow ; and now every part of it is calculated with a* 

 mechanical nicety, thatitmay be the better adapted to the work which 

 it has to perform. 



The harrow is an implement of no less importance than the x>loW, 

 and has, perhaps, undergone as many changes. The rotary, the square, 

 the conical, the single, and the double harrows have all, in their titrn, 

 claimed precedence of each other. The position of the teeth,whether they 

 shall incline backward, forward, or laterally, are all mooted points which 

 elicit the inquiry of the farmer. To attain the great object of pulveriz- 

 ing the soil, the rotary harrow has in it a plausibility which demands 

 attention, and if the ground to be harrowed were always free from stub- 

 ble and weeds it would act well its part; but for practical every-day 

 work, upon all qualities of soil, it is not to be relied upon. Its machin- 

 ery is too complicated, aud it may very well be doubted whether any 

 imi)lement having spindles and Journals which come in contact with 

 plowed ground, will answer the purpose intended. But there are certain 



principles connected with the construction and use of the harrow which 

 should always be kept steadily in view. The teeth should have such a 

 relative position that they should not follow each other in the same
