In offices where two readers are employed, it is advisable that a proof-sheet should be read over by both; because the eye, in traversing the same ground, is liable to be drawn into mistake and oversight. The interest excited by the first reading having abated, a degree of listlessness imperceptibly steals upon the mind, which greatly endangers the correctness of a proof. Should _outs_ or _doubles_ occur in a proof, it ought to be again read by copy, to detect any improper correction in the overrunning or transposition of lines. Figure work should always be read twice by copy. The duty of amending the punctuation should be generally confined to one reader. Where a compositor is liable, in this particular, to the whim or caprice of several readers, he certainly suffers injustice, because his time is unnecessarily frittered away; and not only is the work retarded, but the types are needlessly exposed to injury, to say nothing of the liability of creating fresh errors, &c. Before a manuscript is brought to the printer, it ought to be as perfect as the author can make it. The compositor is bound to “follow the copy,” in word and sentiment, unless, indeed, he meets with instances of wrong punctuation or false grammar, (and such instances are not rare,) which his intelligence enables him to amend. After the matter has been read and corrected in the office, a proof is sent to the author; and, if it corresponds with the copy, the compositor’s responsibility is at an end. He has done all he is paid for; and, should the author desire any changes made in his matter, of course he must pay for them. Sentiments in print look marvellously different from the same ideas in manuscript; and we are not surprised that writers should wish to polish a little; nor do we object to their natural desire of amending or beautifying their mental products. But let them not forget that pay-time will come,—when the item for alterations will loom out with a startling distinctness in the bill. They found it easy in the proof to erase a word or two here and insert a word or two there; without dreaming, perhaps, that in consequence of these little erasures and insertions the compositor would be compelled to alter and reconstruct much of his work. We know of a volume on which the alterations alone have consumed time equal to one man’s work for nearly two and a half years. How unreasonable—nay, how transparently unjust—the expectation that the printer should give gratuitously the time and trouble requisite for the radical changes in the type which an author’s whim or taste may demand!
