submitted. The effect of heat on these gases has not yet been
sufficiently tried, to lead us to any very precise notions of the
additional power which its application to them will supply.
The elasticity of air is sometimes employed as a spring,
instead of steel: in one of the large printing-machines in London
the momentum of a considerable mass of matter is destroyed by
making it condense the air included in a cylinder, by means of a
piston against which it impinges.
352. The effect of competition in cheapening articles of
manufacture sometimes operates in rendering them less durable.
When such articles are conveyed to a distance for consumption, if
they are broken, it often happens, from the price of labour being
higher where they are used than where they were made, that it is
more expensive to mend the old article, than to purchase a new.
Such is usually the case, in great cities, with some of the
commoner locks, with hinges, and with a variety of articles of
hardware.
NOTES:
1. The amount of obstructions arising from the casual fixing of
trees in the bottom of the river, may be estimated from the
proportion of steamboats destroyed by running upon them, The
subjoined statement is taken from the American Almanack for 1832:
βBetween the years 1811 and 1831, three hundred and
forty-eight steamboats were built on the Mississippi and its
tributary streams During that period a hundred and fifty were
lost or worn out,
βOf this hundred and fifty:
worn out 63
lost by snags 36
burnt 14
lost by collision 3
by accidents
not ascertained 34
Thirty-six, or nearly one fourth, being destroyed by accidental
obstructions.
Snag is the name given in America to trees which stand nearly
upright in the stream, with their roots fixed at the bottom.
It is usual to divide off at the bow of the steamboats a
watertight chamber, in order that when a hole is made in it by
running against the snags, the water may not enter the rest of
the vessel and sink it instantly.

has been thus marked in the above extract, from its importance,
and from the conviction that the most extended discussion will
afford additional evidence of its truth.

On Combinations Amongst Masters or Workmen against Each Other
353. There exist amongst the workmen of almost all classes,
certain rules or laws which govern their actions towards each
other, and towards their employers. But, besides these general
principles, there are frequently others peculiar to each factory,
which have derived their origin, in many instances, from the
mutual convenience of the parties engaged in them. Such rules are
little known except to those actually pursuing the several
trades; and, as it is of importance that their advantages and
disadvantages should be canvassed, we shall offer a few remarks
upon some of them.
354. The principles by which such laws should be tried are,
First. That they conduce to the general benefit of all the
persons employed.
Secondly. That they prevent fraud.
Thirdly. That they interfere as little as possible with the
free agency of each individual.
355. It is usual in many workshops, that, on the first
entrance of a new journeyman, he shall pay a small fine to the
rest of the men. It is clearly unjust to insist upon this
payment; and when it is spent in drinking, which is,
unfortunately, too often the case, it is injurious. The reason
assigned for the demand is, that the newcomer will require some
instruction in the habits of the shop, and in the places of the
different tools, and will thus waste the time of some of his
companions until he is instructed. If this fine were added to a
fund, managed by the workmen themselves, and either divided at
given periods, or reserved for their relief in sickness, it would
be less objectionable, since its tendency would be to check the
too frequent change of men from one shop to another. But it
ought, at all events, not to be compulsory, and the advantages to
be derived from the fund to which the workman is invited to
subscribe, ought to be his sole inducement to contribute.
356. In many workshops, the workmen, although employed on
totally different parts of the objects manufactured, are yet
dependent, in some measure, upon each other. Thus a single smith
may be able to forge, in one day, work enough to keep four or
five turners employed during the next. If, from idleness or
intemperance, the smith neglects his work, and does not furnish
the usual supply, the turners (supposing them to be paid by the
piece), will have their time partly unoccupied, and their gains
consequently diminished. It is reasonable, in such circumstances,
that a fine should be levied on the delinquent; but it is
desirable that the master should have concurred with his workmen
in establishing such a rule, and that it should be shown to each
individual previously to his engagement; and it is very desirable
that such fine should not be spent in drinking.
357. In some establishments, it is customary for the master
to give a small gratuity whenever any workman has exercised a
remarkable degree of skill, or has economized the material
employed. Thus, in splitting horn into layers for lanterns, one
horn usually furnishes from five to eight layers; but if a
workman split the horn into ten layers or more, he receives a
pint of ale from the master. These premiums should not be too
high, lest the material should be wasted in unsuccessful
attempts: but such regulations, when judiciously made, are
beneficial, as they tend to produce skill amongst the workmen,
profit to the masters, and diminished cost to the consumers.
358. In some few factories, in which the men are paid by the
piece, it is usual, when any portion of work, delivered in by a
workman, is rejected by the master on account of its being badly
executed, to fine the delinquent. Such a practice tends to remedy
one of the evils attendant upon that mode of payment, and greatly
assists the master, since his own judgement is thus supported by
competent and unprejudiced judges.
359. Societies exist amongst some of the larger bodies of
workmen, and others have been formed by the masters engaged in
the same branches of trade. These associations have different
objects in view; but it is very desirable that their effects
should be well understood by the individuals who compose them;
and that the advantages arising from them, which are certainly
great, should be separated as much as possible from the evils
which they have, unfortunately, too frequently introduced.
Associations of workmen and of masters may, with advantage, agree
upon rules to be observed by both parties, in estimating the
proportionate value of different kinds of work executed in their
trade, in order that time may be saved, and disputes be
prevented. They may also be most usefully employed in acquiring
accurate information as to the number of persons working in the
various departments of any manufacture, their rate of wages, the
number of machines in use, and other statistical details.
Information of this nature is highly valuable, both for the
guidance of the parties who are themselves most interested, and
to enable them, upon any application to government for
assistance, or with a view to legislative enactments, to supply
those details, without which the propriety of any proposed
measure cannot be duly estimated. Such details may be collected
by men actually engaged in any branch of trade, at a much smaller
expense of time, than by persons less acquainted with, and less
interested in it.
360. One of the most legitimate and most important objects of
such associations as we have just mentioned, is to agree upon
ready and certain modes of measuring the quantity of work done by
the workmen. For a long time a difficulty upon this point existed
in the lace trade, which was justly complained of by the men as a
serious grievance; but the introduction of the rack, which counts
the number of holes in the length of the piece, has entirely put
an end to the most fertile cause of disputes. This invention was
adverted to by the Committee of 1812, and a hope was expressed,
in their report, that the same contrivance would be applied to
stocking-frames. It would, indeed, be of great mutual advantage
to the industrious workman, and to the master manufacturer in
every trade, if the machines employed in it could register the
quantity of work which they perform, in the same manner as a
steamengine does the number of strokes it makes. The
introduction of such contrivances gives a greater stimulus to
honest industry than can readily be imagined, and removes one of
the sources of disagreement between parties, whose real interests
must always suffer by any estrangement between them.
361. The effects arising from combinations amongst the
workmen, are almost always injurious to the parties themselves.
There are numerous instances, in which the public suffer by
increased price at the moment, but are ultimately gainers from
the permanent reduction which results; whilst, on the other hand,
the improvements which are often made in machinery in consequence
of βa strikeβ amongst the workmen, most frequently do injury, of
greater or less duration, to that particular class which gave
rise to them. As the injury to the men and to their families is
almost always more serious than that which affects their
employers, it is of the utmost importance to the comfort and
happiness of the former class, that they should themselves
entertain sound views upon this question. For this purpose a few
illustrations of the principle which is here maintained, will
probably have greater weight than any reasoning of a more general
nature, though drawn from admitted principles of political
economy. Such instances will, moreover, present the advantage of
appealing to facts known to many individuals of those classes for
whose benefit these reflections are intended.
362. There is a process in the manufacture of gun barrels for
making what, in the language of the trade, are called skelps. The
skelp is a piece or bar of iron, about three feet long, and four
inches wide, but thicker and broader at one end than at the
other; and the barrel of a musket is formed by forging out such
pieces to the proper dimensions, and then folding or bending them
into a cylindrical form, until the edges overlap, so that they
can be welded together.
About twenty years ago, the workmen, employed at a very
extensive factory in forging these skelps out of bar-iron,
βstruckβ for an advance of wages; and as their demands were very
exorbitant, they were not immediately complied with. In the
meantime, the superintendent of the establishment directed his
attention to the subject; and it occurred to him, that if the
circumference of the rollers, between which the bar-iron was
rolled, were to be made equal to the length of a skelp, or of a
musket barrel, and if also the groove in which the iron was
compressed, instead of being of the same width and depth
throughout, were cut gradually deeper and wider from a point on
the rollers, until it returned to the same point, then the
bar-iron passing between such rollers, instead of being uniform
in width and thickness, would have the form of a skelp. On making
the trial, it was found to succeed perfectly; a great reduction
of human labour was effected by the process, and the workmen
