In this plough, the mouldboard is attached to the sole 

 or slide, in place of bdng connected with the frame or 

 body, as is usually the case ; this arrangement enables, 

 amongst other advantages obtained by it, the beam, the 

 handles, and the body to be made of wrought-irou, and 

 all in solid pieces. The end of the lever neck is made 

 spherical, and passes into a corresponding hollow part 

 made in the front part of the sole. The junction of the 

 two is so complete that, although the easy movement of 

 one within the other is secured,, no dirt or extraneous 

 matters can obtain admittance, to clog and interfere 

 with the action of this most important part of the 

 plough. A conical opening, wider at the end nearest 

 the handles than at that nearest the coulter, is made in 

 the frame j through this the lever of the lever neck is 

 passed, and is allowed, from the conical-shaped aperture, 

 free movement in every direction , laterally as well as 

 vertically. The lever is carried backward towards the 

 handles, and is attached at its further extremity to a 

 snug fixed to the frame or body of the plough. This 

 snug is not a fixture, but is'provided with a bolt and nut, 

 which secure the snug to, and allow it to work up and 

 down in a curved slot or opening made in the framing. 

 This curved slot is of the same radius as a circle de- 

 scribed by the outer end of the lever of the lever neck, 

 the centre being its centre of working in the spherical 

 hollow of the slide or sole. The result of this arrange- 

 ment is a means of giving any required degree of vertical 

 adjustment to the " share," which is attached to the 

 lever neck, so as to give it more or less inclination to 

 the soil ; and this is simply effected by fixing the mov- 

 able snug — bearing the end of the lever— at any desired 

 point in the curved slot or opening. A lateral adjust- 

 ment of the lever, however, is also required, so that the 



lever neck and the share attached to it shall have less or 

 more inclination to the land side as desired. This, again, 

 is simply effected by giving to the movable snug a 

 flat upper table, in which a slot or opening from side to 

 side is made. A bolt connected with the end of the 

 lever of the lever neck passes through this slot, and is 

 secured by a nut resting upon the table of the snug ; by 

 loosening this nut, the bolt, and with it the lever to 

 which it is attached, can be placed in any part of the 

 slot of the snug, and by tightening up the nut there 

 retained. 



By these arrangements any degree of vertical adjust- 

 ment (share with more or less inclination to the soil), 

 and of lateral or side-adjustment (more or less incli- 

 nation to the land side), may bo easily made. 



To secure an ease of draught and a facility in keeping 

 the plough working in a right line, the land-side of the 

 plough is made longer than the sole or slide ; the hard 

 pan or sole made in the bottom of the furrow is thus 

 reduced to a minimum. 



In the department of cultural implements now under 

 consideration, Messrs. Crosskill, of Beverley, exhibited 

 the Revolving Harrows (Marriott's patent). Two cir- 

 cular harrows are joined together by a connecting bar, 

 jointed with an eye to the central bar of each harrow. 

 To the central bar, links are jointed ; and these, 

 provided with shackles, are adjusted to the Whipple or 

 swing-trees. By this arrangement, the harrows are 

 capable of adjusting themselves to any inequality of sur- 

 face and to any irregularity of draught. The giving- 

 and-taking motion, so to speak, produced by the irre- 

 gularities of the surface acted upon, produce a rotatory 

 and cross-action of the harrows, taking a firm hold of 

 the earth, and giving, it is said, a peculiarly fine tilth.
