These _Composing-sticks_ are made of Iron Plate about the thickness of a thin _Scabbord_, and about ten Inches long doubled up square; so as the Bottom may be half an Inch and half a quarter broad, and the Back about an whole Inch broad. On the further end of this Iron Plate thus doubled up, as at _a_ is Soldered on an Iron Head about a _Long-Primmer_ thick; But hath all its outer-edges Basil’d and Fil’d away into a Molding: This Iron Head must be so let into the Plate, and Soldered on to it, that it may stand truly square with the bottom, and also truly square with the Back, which may be known by applying the outer-sides of a square to the Back and Bottom; as I shewed, _Numb._ 3. _Fol._ 38, 39. About two Inches from the Head, in the Bottom, is begun a row of round holes about an Inch assunder, to receive the shank of the _Male-Screw_ that screws the _Sliding-Measures_ fast down to the Bottom; so that the _Sliding-Measures_ may be set nearer or further from the Head, as the Measure of a _Page_ may require. The lower _Sliding-Measure_ marked _d_ is an Iron Plate a _thick Scabbord_ thick, and of the Breadth of the inside of the Bottom; It is about four Inches long, and in its middle hath a Groove through it within half an Inch of the Fore-end, and three quarters of an Inch of the hinder end. This Groove is so wide all the way, that it may receive the Shank of the _Screw_. On the Fore-end of this Plate stands square upright another Iron Head about a _Brevier_ thick, and reaches so high as the top of the Back. The upper _Sliding-Measure_ is made just like the lower, only it is about three quarters of an Inch shorter. Between these two _Sliding-Measures_, _Marginal Notes_ are _Composed_ to any Width. _Compositers_ commonly examine the Truth of their _Stick_ by applying the head of the _Sliding-Measure_ to the inside of the Head of the _Stick_; and if they comply, they think they are square and true made: But this Rule only holds when the Head it self is square. But if it be not, ’tis easy to file the _Sliding-Measures_ to comply with them: Therefore, as aforesaid, the square is the only way to examine them by. ¶. 5. _Of the_ Bodkin. The _Bodkin_ is delineated in Plate 2. at _F_ Its _Blade_ is made of _Steel_, and well tempered, its shape is round, and stands about two Inches without the _Shank_ of the _Handle_. The _Handle_ is turned of soft wood as _Alder_, _Maple_, &c. that when _Compositers_ knock the Head of the _Bodkin_ upon the Face of a Single _Letter_ when it stands too high, it may not batter the Face. ¶. 6. _Of_ Chases, _marked_ G _on the_ Correcting-Stone, _Plate_ 2.
