These _Galleys_ are commonly made of two flat _Wainscot Boards_, each about a quarter and half quarter of an Inch thick, the uppermost to slide in Grooves of the Frame, close down to the undermost, though for small _Pages_ a single Board with two sides for the Frame may serve well enough: Those _Wainscot Boards_ are an Oblong Square, having its length longer than its breadth, even as the form of a _Page_ hath. The three Sides of the Frame are fixed fast and square down on the upper Plain of the undermost Board, to stand about three fifth parts of the height of the _Letter_ above the superficies of the _Slice_. The Sides of the Frame must be broad enough to admit of a pretty many good strong _Oaken Pins_ along the Sides, to be drove hard into the Bottom Board, and almost quite through the Sides of the Frame, that the Frame may be firmly fixed to it: But by no means must they be Glewed on to the Bottom Board, because the _Compositer_ may sometimes have occasion to wet the _Page_ in the _Galley_, and then (the _Galley_ standing aslope upon the _Case_) the Water will soak between the sides of the Frame, and under Board, and quickly loosen it. §. 6. _Of the_ Correcting-stone. The _Correcting-Stone_ marked B in Plate 2. is made of _Marble_, _Purbeck_, or any other Stone that may be made flat and smooth: But yet the harder the Stone is the better; wherefore _Marble_ is more preferable than _Purbeck_. First, Because it is a more compact Stone, having fewer and smaller Pores in it than _Purbeck_. And Secondly, because it is harder, and therefore less subject to be prick’d with the corners of a _Chase_, if through carelessness (as it sometimes happens) it be pitch’d on the Face of the Stone. It is necessary to have it capacious, _viz._ large enough to hold two _Chases_ and more, that the _Compositer_ may sometimes for his convenience, set some _Pages_ by on it ready to _Impose_, though two _Chases_ lye on the _Stone_: Therefore a _Stone_ of about Four Foot and an half long, and Two Foot broad is a convenient size for the generality of Work. This _Stone_ is to be laid upon a strong _Oaken_-wood Frame, made like the Frame of a common Table, so high, that the Face of the _Stone_ may lye about three Foot and an Inch above the Floor: And under the upper Rail of the Frame may be fitted a Row or two of Draw-Boxes, as at _a a a a a a_ and _b b b_ on each of its longest Sides to hold _Flowers_, _Brass-Rules_, _Braces_, _Quotations_, small _Scabbords_, &c. §. 7. _Of_ Letter-Boards, _and_ Paper-Boards.
