STEAM CARRIAGES ON COMMON ROADS.

[One of the most accredited works upon this vital topic is _An

Historical and Practical Treatise upon Elemental Locomotion;_ by Mr.

Alexander Gordon, Civil Engineer. It shows the commercial, political,

and moral advantages; the means by which an elemental power is obtained;

the rise, progress, and description of steam-carriages; the roads upon

which they may be made to travel; and the ways and means for their

general introduction. This arrangement of the subject is exceedingly

well executed by Mr. Gordon, who has added a series of efficient

illustrations--from a diagram simplifying the high-pressure modification

of the steam-engine as applied to steam-carriages, to the last completed

Steam Drag and Carriage attached; while the most material points of Mr.

Gordon's views are fortified by a condensation of the evidence before

the select committee of the House of Commons. All this and much more is

accomplished within two hundred octavo pages, which a less economical

and therefore less praiseworthy editor would have expanded into a costly

quarto. Mr. Gordon's work has thus been planned and executed in the

right spirit: he maintains national benefits which must arise from the

adoption of steam carriages, and he seeks to place his views in the

hands of all who are immediately interested in the subject by means as

efficient as economical. We quote a few extracts, (the most interesting

to the general reader,) from the first chapter, which aims at a cursory

estimate of a few of the leading commercial, political, and moral

advantages which will accrue to the community by the substitution of

inanimate or steam power for animate or horse power, for locomotive

purposes; leaving its spirit of fairness to the just appreciation of

the reader.]

_Economy of Conveyance_.

In a great commercial country like ours, extending its ramifications to

every branch of natural and artificial produce, it is almost superfluous

to remark that a vast capital is sunk annually in the mere transport of

marketable commodities: and which is not only a loss to the seller as

being an unproductive outlay, but entails a heavy increase of expense

to the buyer also upon every article of daily consumption. Any means,

therefore, that will accelerate the conveyance, and at the same time

reduce materially the expense of carriage, bears upon its surface a

great public gain.

Expeditious locomotion, to the commercial world more particularly, in

every mercantile transaction, is equivalent to capital: and such is the

vast importance of economy of time here, that no extra expense is

considered as too great to accomplish the utmost speed. We have this

practically illustrated in the preference which society gives to a

complicated machinery put into motion at an enormous expense, to

travelling by the winds of heaven which cost nothing.

To the merchant time gained is equal to money: for time occupied in

travelling is just so much profitable employment lost. Time occupied

in the transport of goods is equivalent to so much interest of capital

spent: for a thousand pounds invested in merchandise is unproductive so

many days as the transport is tedious. That part of the capital of an

individual which is employed in the carrying of his goods to and from

market, is so much abstracted from his means of producing more of the

article in which he exerts his ingenuity and labour, whether it be in

agriculture or manufacture.

Easy communication lessens the time occupied in the transport; and a

saving of time lessens the distance, or our notion of distance. This

effects a saving of money: and a saving of money permits of a greater

employment of capital. The man who can only afford to keep one traveller

soliciting orders for his goods, will thus be enabled to keep two;

because the expense of travelling will be reduced a half. Or it may be,

he will find it more advantageous to employ the saving in the production

of a more delicate and desirable article in the way of his trade. The

increased traffic from place to place will give likewise an impulse to

business, which, in the present stagnant times, is most desirable. The

manufacturer in Scotland will find the London market more easily arrived

at: and the merchant in the metropolis will be able to get his orders

more rapidly given and executed. A conveyance which, in good management,

would be a weekly one, is, in bad management, a monthly one: and the

carrier is obliged to quadruple his charge for the transport. To meet

this charge the merchant has to add to the cost of the article, and so

on throughout the various gradations of mercantile transition, until the

consumer pays the necessarily increased price. Hence, whatever reduces

the price of transportation, reduces the price of the commodity

transported. Whatever reduces the traveller's time, reduces his claim

for compensation, and (competition being always at work) he is content

with a smaller profit upon his merchandise. If a scarcity of any article

occurs at one point of the kingdom, the monopolist there cannot continue

his increased price for any duration of time. Commerce may, in this

respect, be resembled to water, for, if not obstructed, it will always

circulate till it finds its level. An opening or channel being

furnished, an equalised supply will make its way wherever required.

Thus we see that the strength, wealth, and happiness of a nation, depend

very much upon facility of communication. The ill-defended spot in the

empire is alive to the reality, that subsidies having bad roads or a

tedious navigation to pass may arrive too late to present an effectual

resistance to a plundering enemy. The hard-working emigrant of a remote

settlement, distant from a market, feels the difficulty and loss he

sustains in bringing produce to the spot where merchants and dealers

meet for the purposes of exchange. A spot uncommunicated with may be

visited by the honors of famine, and no channel exist for conveying

thither the food required. A grievous pestilence may sweep off an

isolated people before the aid of the physician can arrive to arrest

its progress.

Such facts are obvious to even the most indifferent observers of human

society. Yet, nevertheless, there have been, and are, short-sighted

individuals, in every gradation of it, with minds and views so warped

and distorted by an ignorant selfishness, that they have opposed

every improvement which tended to make the least change in their

long-established habits. Such persons were they, who, during the last

century, promoted petitions from counties in the neighbourhood of

London, praying Parliament not to extend the turnpike-roads into remoter

parts of the country, lest these remote districts, by means of a less

expensive labour, should be able to sell their agricultural products

in the London markets at a cheaper rate than themselves!--and such in

our own day are the attempts made to put down steam conveyance. How

short-sighted we are! Did we consult our own advantage we should see

that those facilities of communication, against which we oppose

ourselves, are the growing sinews of a greater fabric of wealth and

prosperity.

Such are the numerous and important advantages, in a commercial point of

view, which will result to society from the substitution of elementary

for physical power. But even these, great though they be, are of

trifling consideration when compared with the immense benefits which

will result from the substitution when brought into operation as an

economic principle.

_Substitution of Steam for Horse Power_.

[Mr. Gordon then refers to the conclusion of political economists "that

the grand source of all our evils is _redundancy_ of population; or in

other words, an increase of animated life _beyond_ the nourishment

adequate to support it."]

The substitution of inanimate for animate power, if not the panacea which

is to cure all the evils of our condition, is at least one that comes

recommended as a matter of fact--easy of operation, and effectual in its

result. If want of food, or, in other words, redundancy of population

be the bane of the country, it does not propose to meet that evil by a

visionary project, tending in its operation to unhinge society--tedious in

its process, and ending at length in bitter disappointment--but it meets

the evil directly, substantially, and effectually, by the substitution of

food.

And how are all these immense advantages to be effected?--By the

substitution of inanimate for animate power. At present, the animate

power employed in the commercial transportations of this great kingdom is

estimated to amount to two millions of horses: each horse consumes as much

food as is necessary for the support of eight men. Hence the conversion of

its consumption to purposes of human existence would, if carried to this

practical extent, amount to a quantity of food equal to support sixteen

millions of people.

Where the product is so enormous--so vastly beyond our immediate

necessities--it is not requisite to go into any minutiae of detail. To

calculate all the gains we will leave to the political economist, as also

to bring the matter out in its fair proportions; but to establish the

matter clearly within the bounds of a safe, an easy, and practical issue,

we have merely to state, that a conversion of food from a physical to a

moral purpose, adequate to the supply of one-fourth part of the above

aggregate estimate, that is to say, to four millions, is amply sufficient

to relieve us at the present moment from that pressure of pauperism which

sits like an incubus upon the energies of the nation, and which will

precipitate us, if not timely avoided, into speedy and irretrievable ruin.

Now the suppression of the stage-horses upon our principal thoroughfares,

and of the dray-horses in the great commercial towns, may be calculated

to economize a saving of food equivalent to the supply of the above number

of human beings.

It is, perhaps, not superfluous to remark, that the amount of food,

equal to the supply of the said four millions, is not the produce of an

extended agriculture and proportionate outlay, but is just _that part_

of the annual produce of the country, subtracted from the whole, which

is at present required for the mere purpose of _transportation_--i.e. to

feed the animals used for draught,--and is consequently a dead loss as

unproductive capital.

In addition to the evil arising from such a consumption of unproductive

food, is also to be considered the very great loss consequent upon the

heavy capital sunk in _horse_ purchase. Were this viewed, as properly it

ought, as money withheld from other purposes of trade, and which might

be more advantageously invested, our capitalists and men of science

would not oppose the substitution of inanimate for animate power in the

way they have done. Neither, did the landed interest maturely weigh the

varied benefits it will produce in agriculture, would they view it in

the light of an invasion upon their respective interests. They do not

give a _quid_ without receiving a _quo_ every way as valuable. The

reduction of farm consumption--the bugbear of the project--will be

met and compensated by a steady and proportionate demand from other

quarters. Whilst in the United Kingdom, the 8,100,000 acres of land now

required to feed the horses, together with the capital sunk in their

purchase, will, when both applied to other and general purposes, amply

compensate for the exchange.

In order more readily to show one effect, let the horses be considered

only 1,000; a smaller number may not make the argument so difficult. Let

us reduce _this_ number, and the farmer may then turn his oat-ground

into wheat-ground; and instead of so much land being employed to furnish

food for a thousand horses, the same land, when turned into tillage fit

to sow wheat upon, will produce sufficient bread-corn to feed two

thousand poor families.

Again, if instead of 20,000 horses, we keep 30,000 fat oxen, butchers'

meat will be always cheap to the operative classes, whilst the quantity

of tallow will of course make candles cheap: and so many hides lower the

price of leather, and of shoes and all other articles made of leather.

Or the same quantity of land may then keep thirty thousand cows, the

milk of which will make both butter and cheese cheaper to the poor,

as well as the labouring manufacturer; all which articles are very

considerable, and of material moment in the prices of our manufacturers,

as they, in a great measure, work their trade to rise and fall in price,

according to the cheapness of their materials and the necessaries of

life. The same may be said in favour of more sheep and woollen cloths.

(_To be concluded in our next_.)
