It is the general custom to print of every work what is termed an _even_ number,—either 250, 500, 750, 1000, &c. These quantities are given out for the wetter in _tokens_,—viz.: for 250 sheets, one token, containing 10 quires 18 sheets; for 500, two tokens, one 11 quires, and the other 10 quires and a half; for 750, three tokens, two of them 11 quires each, and the other 10 quires 6 sheets; and for 1000, four tokens, three of them 11 quires each, and the other 10 quires. If a work is printed in half-sheets, it of course requires only half the above quantities. It would be difficult to form any positive and invariable rule for the quantity to be given out for short numbers, as it must depend in some degree upon the quality of the paper. The more expensive papers, on which, generally, short numbers or line copies are printed, must be given out more sparingly than common paper, and the tympan and register sheets be supplied by a more common sort, cut to the size of the finer. For numbers up to 150, on ordinary paper, six sheets over will be sufficient. Some publishers are very testy on this point of allowance for waste. In giving out paper for what are termed _jobs_, the amount necessary can easily be found by a simple calculation in division. For example, a job, (label or any thing else,) 750 in number, 32 on a sheet, will require 24 sheets, which will give an overplus of 18. Where a sheet has to be cut into many parts, allowance must be made for accidents. The overplus sheets are allowed for tympan-sheets, register-sheets, and other incidents, such as bad sheets, faults committed in rolling, pulling, bad register, &c.; in any of these casualties, the pressman doubles the sheet in the middle and lays it across the heap. In laying out the paper, the warehouseman reverses every other token, to enable the wetter to distinguish the different tokens. When this is done, he labels the heap, thus: _American Printer, May 10, 1878_,—that the pressman may know how long it has been wet, and the state it is in for working. 32)750(23 64 --- 110 96 --- 14 HANGING UP PAPER TO DRY. When the paper is worked off and counted, the warehouseman carries the heap to the drying-room, where the poles are fixed for the purpose of hanging the sheets upon to dry, and lays it down on a table of convenient height, with one end of the heap toward him. He then takes the handle of the peel in one hand, and lays the top part down upon the heap, so that the upper edge may reach near the middle of the sheet; then, with the other hand, he doubles over as much of the printed paper as he thinks sufficient to hang up at one lift, which should be about twelve sheets, according to the pole-room to hang them.
