of labour and materials at home, and keep open the foreign market. By neglecting that salutary measure, the Dutch have lost all their manufactures, a neglect that has<158> greatly benefited both England and France. The Dutch indeed act prudently in with-holding that benefit as much as possible from their powerful neighbours: to prevent purchasing from them, they consume the manufactures of India.
The manufactures of Spain, once extensive, have been extirpated by their gold and silver mines. Authors ascribe to the same cause the decline of their agriculture; but erroneously: on the contrary, superfluity of gold and silver is favourable to agriculture, by raising the price of its productions. It raises also, it is true, the price of labour; but that additional expence is far from balancing the profit made by high prices of whatever the ground produces. Too much wealth indeed is apt to make the tenant press into a higher rank: but that is easily prevented by a proper heightening of the rent, so as always to confine the tenant within his own sphere.
As gold and silver are essential to commerce, foreign and domestic, several commercial nations have endeavoured most absurdly to bar the exportation by penal laws; forgetting that gold and silver will<159> never be exported while the balance of trade is on their side, and that they must necessarily be exported when the balance is against them. Neither do they consider, that if a people continue industrious, they cannot be long afflicted with an unfavourable balance; for the value of money, rising in proportion to its scarcity, will lower the price of their manufactures, and promote exportation: the balance will turn in their favour; and money will flow in, till by plenty its value be reduced to a par with that of neighbouring nations.
It is an important question, Whether a bank, upon the whole, be friendly to commerce. It is undoubtedly a spur to industry, like a new influx of money: but then, like such influx, it raises the price of labour and of manufactures. Weighing these two facts in a just balance, the result seems to be, that in a country where money is scarce, a bank properly constituted is a great blessing, as it in effect increases the quantity of money, and promotes industry and manufactures; but that in a country which possesses money sufficient for extensive commerce, the only bank that will not injure foreign commerce, is what<160> is erected for supplying the merchant with ready money by discounting bills. At the same time, much caution and circumspection is necessary with respect to banks of both kinds. A bank erected for discounting bills, ought to be confined to bills really granted in the course of commerce; rejecting fictitious bills drawn merely for procuring a loan of money. And with respect to a bank purposely erected for lending money, there is great danger of extending credit too far; not only with respect to the bank itself, but with respect to the nation in general, by raising the price of labour and of manufactures, which is the never failing result of too great plenty of money, whether coin or paper.
The different effects of plenty and scarcity of money, have not escaped that penetrating genius, the sovereign of Prussia. Money is not so plentiful in his dominions as to make it necessary to withdraw a quantity by heaping up treasure. He indeed always retains in his treasury six or seven millions Sterling for answering unforeseen demands: but being sensible that the withdrawing from circulation any larger sum would be prejudicial to commerce, <161> every farthing saved from the necessary expence of government, is laid out upon buildings, upon operas, upon any thing rather than cramp circulation. In that kingdom, a bank established for lending money would promote industry and manufactures.<162>
Some useful arts must be nearly coeval with the human race; for food, cloathing, and habitation, even in their original simplicity, require some art. Many other arts are of such antiquity as to place the inventors beyond the reach of tradition. Several have gradually crept into existence, without an inventor. The busy mind however, accustomed to a beginning in things, cannot rest till it find or imagine a beginning to every art. Bacchus is said to have invented wine; and Staphylus the mixing water with wine. The bow and arrow are ascribed by tradition to Scythos, son of Jupiter, though a weapon all the world over. Spinning is so useful, that it must be honoured with<163> some illustrious inventor: it was ascribed by the Egyptians to their goddess Isis; by the Greeks to Minerva; by the Peruvians to Mamma Ella, wife to their first sovereign Mango Capac; and by the Chinese to the wife of their Emperor Yao. Mark here by the way a connection of ideas: spinning is a female occupation, and it must have had a female inventor.*
In the hunter-state, men are wholly employed upon the procuring food, clothing, habitation, and other necessaries; and have no time nor zeal for studying conveniencies. The ease of the shepherd-state affords both time and inclination for useful arts; which are greatly promoted by numbers who are relieved by agriculture from bodily labour: the soil, by gradual improvements in husbandry, affords plenty with less labour than at first; and<164> the surplus hands are employed, first, in useful arts, and, next, in those of amusement. Arts accordingly make the quickest progress in a fertile soil, which produces plenty with little labour. Arts flourished early in Egypt and Chaldea, countries extremely fertile.
When men, who originally lived in caves like some wild animals, began to think of a more commodious habitation, their first houses were extremely simple; witness those of the Canadian savages, than which none can be more simple, even at present. Their houses, says Charlevoix, are built with less art, neatness, and solidity, than those of the beavers; having neither chimneys nor windows: a hole only is left in the roof, for admitting light and emitting smoke. That hole must be stopped when it rains or snows; and, of course, the fire is put out, that the inhabitants may not be stifled with smoke. To have passed so many ages in that manner without thinking of any improvement, shows how greatly men are influenced by custom. The blacks of Jamaica are still more rude in their buildings: their huts are erected without even a hole<165> in the roof; and, accordingly, at home they breathe nothing but smoke.
Revenge produced early hostile weapons. The club and the dart are obvious inventions: not so the bow and arrow; and for that reason it is not easy to say how that weapon came to be universal. As iron differs from other metals, being seldom found pure, it was a late discovery: at the siege of Troy, spears, darts, and arrows, were headed with brass. Menestheus, who succeeded Theseus in the kingdom of Athens, and led fifty ships to the siege of Troy, was reputed the first who marshalled an army in battle-array. Instruments of defence are made necessary by those of offence. Trunks of trees, interlaced with branches, and supported with earth, made the first fortifications; to which succeeded a wall finished with a parapet for shooting arrows at besiegers. As a parapet covers but half of the body, holes were left in the wall from space to space, no larger than to give passage to an arrow. Besiegers had no remedy but to beat down the wall: a battering ram was first used by Pericles the Athenian, and perfected by the Carthaginians at the siege of<166> Gades. To oppose that formidable machine, the wall was built with advanced parapets for throwing stones and fire upon the enemy, which kept him at a distance. A wooden booth upon wheels, and pushed close to the wall, secured the men who wrought the battering ram. This invention was rendered ineffectual, by surrounding the wall with a deep and broad ditch. Besiegers were reduced to the necessity of inventing engines for throwing stones and javelins upon those who occupied the advanced parapets, in order to give opportunity for filling up the ditch; and ancient histories expatiate upon the powerful operation of the catapulta and balista. These engines suggested a new invention for defence: instead of a circular wall, it was built with salient angles, like the teeth of a saw, in order that one part might flank another. That form of a wall was afterwards improved, by raising round towers upon the salient angles;
