_Fig._ 3. is the Share, lying Bottom upwards. _a_ is its Point. _b_ the Socket, Three Inches long, Seven Sixteenths of an Inch broad. _c_ is the Hole, by which it is fastened up to the Sheat. _d_ is another Hole, which is never made use of, except when the Share, being fasten’d up by the other Hole, inclines to either Side; then we draw it right by a Nail driven into this Hole. _e_, _e_, are Two very small Notches, into which the Sides of the Trunk are jointed, to protect them from being torn out by the Earth or Stones that might rub against them, _f_ is the Tail of the Share, which, when it is in its Place, will make the right Angle before described in _Fig._ 2. and from which Tail, to the Fore-part of the Socket, is the Length of the Bottom of the Sheat, _viz._ Six Inches and an half. The Breadth of the Share Three quarters of an Inch. _Fig._ 4. shews one Side of the Share. The prick’d Line _a e_ shews the Bevel of the Fore-end of the Socket, the upper Edge of which must bear upon the Fore-part of the Sheat below _f_ in _Fig._ 2. and the other Part of the Share will bear against the Bottom of the Sheat, from _d_ to _c_, and will be fastened up by a flat Nail, passing thro’ the foremost Hole of the Share, and entering the Hole _g_ in the Sheat; which Nail being bended in the said Hole (which Hole should be at least an Inch Diameter) will hold the Share fast to the Sheat; and, by unbending this Nail, the Share may be easily taken off, upon Occasion, without damaging the Sheat. _Note_, This Hole in the Share ought to be wider below than above, and the Head of the Nail of the same Shape; or else, as the Share wears thinner, it might come off. The prick’d Line, near the Fore-part of the Sheat, shews where a Shoulder must be cut on each Side of it, because otherwise the Sheat, being thicker than the Breadth of the Socket of the Share, could not enter it: But take care, that the Share do not bear against these Shoulders. _Fig._ 5. is one Side of the Trunk, being a thin Plate of Iron, and is often made of the Blade of an old Scythe: It is to be riveted on to one Side of the Sheat, to another of the same on the opposite Side, by Three Rivets passing thro’ them both, with the Sheat in the Middle of them; which Holes appear both in the Plate and in the Sheat. These thus riveted on do form the Trunk at the Back of the Sheat. The whole Breadth of this Plate is an Inch and Three quarters; but Three-eighths of an Inch being riveted on to the Sheat, there remains but an Inch and Three-eighths for the Trunk. The Length of the Plate is the same with the Depth of the Sheat and Share, except that it should not reach to the Bottom of the Share, by about the Thickness of a Barley-corn, to the end that it may not bear against the Ground, as the Share doth. The Notch at the Bottom of the Plate is that which answers the Notch in the Tail of the Share: The Corner of the Plate at _a_ we make a little roundish, that it may not wear against the Ground.
