continuing the same as before; or, the demand continuing the same as before, it may have been owing altogether to the gradual diminution of the supply; the greater part of the mines which were then known in the world being much exhausted, and consequently the expense of working them much increased; or it may have been owing partly to the other of those two circumstances. In the end of the fifteenth and beginning of the sixteenth centuries, the greater part of Europe was approaching towards a more settled form of government than it had enjoyed for several ages before. The increase of security would naturally increase industry and improvement; and the demand for the precious metals, as well as for every other luxury and ornament, would naturally increase with the increase of riches. A greater annual produce would require a greater quantity of coin to circulate it; and a greater number of rich people would require a greater quantity of plate and other ornaments of silver. It is natural to suppose, too, that the greater part of the mines which then supplied the European market with silver might be a good deal exhausted, and have become more expensive in the working. They had been wrought many of them from the time of the Romans.
It has been the opinion, however, of the greater part of those who have written upon the price of commodities in ancient times that, from the Conquest, perhaps from the invasion of Julius Caesar till the discovery of the mines of America, the value of silver was continually diminishing. This opinion they seem to have been led into, partly by the observations which they had occasion to make upon the prices both of corn and of some other parts of the rude produce of land; and partly by the popular notion that as the quantity of silver naturally increases in every country with the increase of wealth, so its value diminishes as its quantity increases.
In their observations upon the prices of corn, three different circumstances seem frequently to have misled them.
First, in ancient times almost all rents were paid in kind; in a certain quantity of corn, cattle, poultry, etc. It sometimes happened, however, that the landlord would stipulate that he should be at liberty to demand of the tenant, either the annual payment in kind, or a certain sum of money instead of it. The price at which the payment in kind was in this manner exchanged for a certain sum of money is in Scotland called the conversion price. As the option is always in the landlord to take either the substance or the price, it is necessary for the safety of the tenant that the conversion price should rather be below than above the average market price. In many places, accordingly, it is not much above one-half of this price. Through the greater part of Scotland this custom still continues with regard to poultry, and in some places with regard to cattle. It might probably have continued to take place, too, with regard to corn, had not the institution of the public fiars put an end to it. These are annual valuations, according to the judgment of an assize, of the average price of all the different sorts of grain, and of all the different qualities of each, according to the actual market price in every different county. This institution rendered it sufficiently safe for the tenant, and much more convenient for the landlord, to convert, as they call it, the corn rent, rather at what should happen to be the price of the fiars of each year, than at any certain fixed price. But the writers who have collected the prices of corn in ancient times seem frequently to have mistaken what is called in Scotland the conversion price for the actual market price. Fleetwood acknowledges, upon one occasion, that he had made this mistake. As he wrote his book, however, for a particular purpose, he does not think proper to make this acknowledgment till after transcribing this conversion price fifteen times. The price is eight shillings the quarter of wheat. This sum in 1423, the year at which he begins with it, contained the same quantity of silver as sixteen shillings of our present money. But in 1562, the year at which he ends with it, it contained no more than the same nominal sum does at present.
Secondly, they have been misled by the slovenly manner in which some ancient statutes of assize had been sometimes transcribed by lazy copiers; and sometimes perhaps actually composed by the legislature.
The ancient statutes of assize seem to have begun always with determining what ought to be the price of bread and ale when the price of wheat and barley were at the lowest, and to have proceeded gradually to determine what it ought to be, according as the prices of those two sorts of grain should gradually rise above this lowest price. But the transcribers of those statutes seem frequently to have thought it sufficient to copy the regulation as far as the three or four first and lowest prices, saving in this manner their own labour, and judging, I suppose, that this was enough to show what proportion ought to be observed in all higher prices.
Thus in the Assize of Bread and Ale, of the 51st of Henry III, the price of bread was regulated according to the different prices of wheat, from one shilling to twenty shillings the quarter, of the money of those times. But in the manuscripts from which all the different editions of the statutes, preceding that of Mr. Ruffhead, were printed, the copiers had never transcribed this regulation beyond the price of twelve shillings. Several writers, therefore, being misled by this faulty transcription, very naturally concluded that the middle price, or six shillings the quarter, equal to about eighteen shillings of our present money, was the ordinary or average price of wheat at that time.
In the Statute of Tumbrel and Pillory, enacted nearly about the same time, the price of ale is regulated according to every sixpence rise in the price of barley, from two shillings to four shillings the quarter. That four shillings, however, was not considered as the highest price to which barley might frequently rise in those times, and that these prices were only given as an example of the proportion which ought to be observed in all other prices, whether higher or lower, we may infer from the last words of the statute: et sic deinceps crescetur vel diminuetur per sex denarios. The expression is very slovenly, but the meaning is plain enough: "That the price of ale is in this manner to be increased or diminished according to every sixpence rise or fall in the price of barley." In the composition of this statute the legislature itself seems to have been as negligent as the copiers were in the transcription of the others.
In an ancient manuscript of the Regiam Majestatem, an old Scotch law book, there is a statute of assize in which the price of bread is regulated according to all the different prices of wheat, from tenpence to three shillings the Scotch boll, equal to about half an English quarter. Three shillings Scotch, at the time when this assize is supposed to have been enacted were equal to about nine shillings sterling of our present money. Mr. Ruddiman seems to conclude from this, that three shillings was the highest price to which wheat ever rose in those times, and that tenpence, a shilling, or at most two shillings, were the ordinary prices. Upon consulting the manuscript, however, it appears evidently that all these prices are only set down as examples of the proportion which ought to be observed between the respective prices of wheat and bread. The last words of the statute are: reliqua judicabis secundum proescripta habendo respectum ad pretium bladi. "You shall judge of the remaining cases according to what is above written, having a respect to the price of corn."
Thirdly, they seem to have been misled, too, by the very low price at which wheat was sometimes sold in very ancient times; and to have imagined that as its lowest price was then much lower than in later times, its ordinary price must likewise have been much lower. They might have found, however, that in those ancient times its highest price was fully as much above, as its lowest price was below anything that had even been known in later times. Thus in 1270, Fleetwood gives us two prices of the quarter of wheat. The one is four pounds sixteen shillings of the money of those times, equal to fourteen pounds eight shillings of that of the present; the other is six pounds eight shillings, equal to nineteen pounds four shillings of our present money. No price can be found in the end of the fifteenth, or beginning of the sixteenth century, which approaches to the extravagance of these. The price of corn, though at all times liable to variation, varies most in those turbulent and disorderly societies, in which the interruption of all commerce and communication hinders the plenty of one part of the country from relieving the scarcity of another. In the disorderly state of England under the Plantagenets, who governed it from about the middle of the twelfth till towards the end of the fifteenth century, one district might be in plenty, while another at no great distance, by having its crop destroyed either by some accident of the seasons, or by the incursion of some neighbouring baron, might be suffering all the horrors of a famine; and yet if the lands of some hostile lord were interposed between them, the one might not be able to give the least assistance to the other. Under the vigorous administration of the Tudors, who governed England during the latter
