with the setting-up of the next, and so on with a sufficient number of lines to fill his 

 stick, and then lifts the handful, or mass of types, out of the stick, and places them 

 upon a galley, or oblong tray of wood or metal, having an edge to the left side and 

 top half an inch in height. This operation of filling and emptying the stick is 

 repeated till the galley is sufficiently full, or the taking of copy is finished ; when the 

 matter, as it is then called, is taken away by the clicker, 

 who divides it into the required lengths of pages, placing 

 head-lines, signatures, &c., and binding them round 

 tightly with cord. The clicker then lays down the pages 

 in their proper positions on the imposing stone, a flat, 

 smooth slab of stone, or, better, of iron. The chase, a 

 frame of iron, divided into compartments like the sashes 

 of a window, is put round the pages, and the form dressed 

 thus : a set of furniture, consisting of slips of wood or metal, 

 about half an inch in height, and of various thicknesses, 

 is placed, some at the head, called head-sticks, some 

 between the pages, called gutters, and others at the sides 

 and feet, called side- and foot-sticJcs. The side- and foot- 

 sticks are larger at one end than at the other, so that 

 small wedges of wood, or quoins, may be driven tightly 

 between them and the sides of the chase, locking up the 

 types so firmly, that the form, as the mass is called (fig. 

 1674), may be carried from place to place with perfect safety. A form cf eight 

 pages of this Dictionary contains between 40,000 and 50,000 separate letters and 



The sizes of books are reckoned by the number of leaves into which a sheet of 

 paper is folded. Thus the largest size is broadside, or the whole size of the sheet ; 

 folio, or half the sheet ; quarto, or a sheet folded into four leaves ; octavo, or the sheet 

 folded into eight leaves ; duodecimo, or the sheet folded into twelve leaves ; and so on. 

 In imposing, the pages are of course laid down in positions the reverse of those they 

 will take when printed. The following Tables show the mode of imposing some of 

 the most common sizes. 



When the process of imposing is completed, the form is carried to a press, and an 

 impression is taken, called the first proof. This proof, with the MS., is handed to the 

 corrector of the press, or reader, and a reading boy reads the copy to him while he 

 examines the proof and marks the necessary corrections and errors of the compositor. 

 In correcting a proof-sheet a set of symbols are used for the purpose of calling the 

 attention of the compositor to the several kinds of errors, and to direct him how they
