Thus, in one
hour, four thousand sheets of paper are printed on one side; and
an impression of twelve thousand copies, from above three hundred
thousand moveable pieces of metal, is produced for the public in
six hours.
333. The effect of machinery in printing other periodical
publications, and of due economy in distributing them, is so
important for the interests of knowledge, that it is worth
examining by what means it is possible to produce them at the
small price at which they are sold. 'Chambers' Journal', which is
published at Edinburgh, and sold at three halfpence a number,
will furnish an example. Soon after its commencement in 1832, the
sale in Scotland reached 30,000, and in order to supply the
demand in London it was reprinted; but on account of the expense
of 'composition' it was found that this plan would not produce
any profit, and the London edition was about to be given up, when
it occurred to the proprietor to stereotype it at Edinburgh, and
cast two copies of the plates. This is now done about three weeks
before the day of publication--one set of plates being sent up
to London by the mail, an impression is printed off by steam: the
London agent has then time to send packages by the cheapest
conveyances to several of the large towns, and other copies go
through the booksellers' parcels to all the smaller towns.
