A DAY AT THE BOOKBINDERY OF LIPPINCOTT, GKAMBO, 4 Co.

Havino given our readers, in our last artiele, an insight into the meehanieal operation required to set the types and print the sheets of a book, we this month take them to one of the largest publishing heuses in the eountry, that they may know something of the manner in whieh books are bound and eireulated through the Union. We are enabled to do this through the eourtesy of Messrs. Lippineott, Grambo, A Co., whe allowed us the privilege of examining their extensive range of rooms, a general

idea of the labor performed in whieh we shall endeavor to give in the following pages.

When we reeeived the eonsent of the senior partner of the firm for this privilege, we expeeted to sesmueh that would surprise us, but were not prepared to find so vast an amount of business performed, or eapital invested. We were eompletely lost in astonishment, as we passed through room after room peopled with workmen engaged in the various branehes to whieh the rooms were devoted. It wns our intention, at first, to give a deseription of bookhinding only, but were so struek with the extent of labor employed in the establishment, that we have eoneluded, so far as we are able, to make our readers aequainted with the general maehinery of a largo publishing house, hoping it may prove as interesting to them as it was to us. We will first deseribe the

BOOKBINDING TtEPAItTMENT.

After the sheets are finished in the drying-room, as deseribed in our last, and are pressed, they are sent in bundles to the hindery, where they are opened and given out to the girls employed to fold them.

When the whole of the impression has been folded, eaeh sheet is laid out in a row, in piles of one hundred. The folder then takes one from the top of eaeh pile, and, plaeing them together, they form the printed matter of a book. The eopies thus eolleeted are knoeked evenly together, and put into a hydraulie press, between steel boards, in rows of two deep, and as many along-side of eaeh other as the boards will hold, for the purpose of eompressing them into a eompaet form. If the work be

newly printed, eare must be taken not to allew it to set off, as the fresh ink has a tendeney to make an impression on the opposite page, as was generally the ease with now books when eompressed by the old method, whieh was to beat them on a large smooth stone with a east-iron bell-shaped hammer weighing twelve or fourteen pounds. This required some skill so as to eompress or eondense the sheets without marking them with the edge of the hammer, and to give the paper a smooth polished surfaee. This proeess was very mueh improved some years ago by a rolling-press, eonsisting of two iron eylinders, mounted and set in the usual way at any required distanee apart. A number of sheets, varying from six to fourteen, aeeording to the size, being

i plaeed between two tinned iron plates, are passed j through the rollers. This method not only renders \ the paper smoother than by hammer-beating, but ( the eompression of the book is one-eixtb greater, a i very desirable objeet, inasmueh as the book-shelves \ will eontain nearly one-sixth more books. These \ superior effeets are also produeed by the rollers in > one-twentieth of the time required by the hammer. j This method is now adopted for books that have \ been printed some time, in whieh the ink is proper; ly set, and also for books that require rehinding. s After pressing, rolling, or hammering, eaeh book s is eollated, to see that all the signatures run pro( perly, and the plates, if any, are inserted in their j proper plaees. The waste leaves are added at the < beginning and end; the haek and head are then j knoeked up square, and one side of the book is ( plaeed on a pressing-board of the size of the book itself, and another similar board is laid on the upper side of the book, taking eare to let the haek of the. sheets projeet about half an ineh between the two boards. The workman then grasps the boards firmly between the thumb and fingers of the left j hand, and lowers them into the eutting-press, whieh j eonsists of two strong wooden eheeks e e, eonneeted j by two slide hars b b, and two wooden serows t *. j The use of the two guides on one of the eheeks will

i be explained hereafter; but it maybe remarked that

> when these guides are not wanted, the press is

i turned eompletely over, so that these guides maybe

\ at the bottom, and out of the way. When the

I sheets are lowered between the eheeks er, the press

\ is serowed up tight by working an iron har in the

J heads of the serows. The man then passes a tenon

^ saw aeross the haek of the sheets, so as to make a

\ number of grooves, aeeording to the size of the

> book, for the reeeption of the eords or hands for

s holding the threads in the sowing, and also for

\ seeuring the boards whieh are to form the side

\ eovers. The number of hands depends upon the

i style of hinding or method of finishing the book;

; boarded books, or books bound in eloth, have only

( two hands. But in the better deseriptions of hind

< ing, 32mos. sometimes have three hands; 18mosM

\ 12mos., 8vos., and two-leaf 4tos., have four hands:

; royal oetavos and whole sheet 4tos., five hands: and

j folios from five to seven hands. In addition to

1 these grooves for the hands, a groove is also formed

\ at eaeh end for the eateh or kettle stiteh. Suppos
