In the one case, the product is entirely made by a single machine,
 which performs all the various operations previously done by one handicraftsman
 with his tool; as, for instance, by a weaver with his loom; or by several
 handicraftsman successively, either separately or as members of a system
 of Manufacture. [15] For example, in the manufacture358 of envelopes, one man folded the paper with the folder, another laid on
 the gum, a third turned the flap over, on which the device is impressed,
 a fourth embossed the device, and so on; and for each of these operations
 the envelope had to change hands. One single envelope machine now performs
 all these operations at once, and makes more than 3,000 envelopes in an
 hour. In the London exhibition of 1862, there was an American machine for
 making paper cornets. It cut the paper, pasted, folded, and finished 300
 in a minute. Here, the whole process, which, when carried on as Manufacture,
 was split up into, and carried out by, a series of operations, is completed
 by a single machine, working a combination of various tools. Now, whether
 such a machine be merely a reproduction of a complicated manual implement,
 or a combination of various simple implements specialised by Manufacture,
 in either case, in the factory, i.e., in the workshop in which machinery
 alone is used, we meet again with simple co-operation; and, leaving the
 workman out of consideration for the moment, this co-operation presents
 itself to us, in the first instance, as the conglomeration in one place
 of similar and simultaneously acting machines. Thus, a weaving factory
 is constituted of a number of power-looms, working side by side, and a
 sewing factory of a number of sewing-machines all in the same building.
 But there is here a technical oneness in the whole system, owing to all
 the machines receiving their impulse simultaneously, and in an equal degree,
 from the pulsations of the common prime mover, by the intermediary of the
 transmitting mechanism; and this mechanism, to a certain extent, is also
 common to them all, since only particular ramifications of it branch off
 to each machine. Just as a number of tools, then, form the organs of a
 machine, so a number of machines of one kind constitute the organs of the
 motive mechanism.
