As by my title I profess to be addressing myself to Englishmen, I think I need not tell them that they live by trade; that their commerce has raised them from what they were to what they are, and may, if cultivated and improved, raise them yet further to what they never were; and this in few words is an index of my present work. It is worth an Englishman's remark, that we were esteemed as a growing thriving nation in trade as far back as in the reigns of the two last Henries; manufactures were planted, navigation increased, the people began to apply, and trade bringing in wealth, they were greatly encouraged; yet in king Henry VIII.'s reign, and even towards the latter end of it, too, we find several acts of parliament passed for regulating the price of provisions, and particularly that beef and pork should not be sold in the market for more than a halfpenny per pound avoirdupoise, and mutton and veal at three farthings. As the trading men to whom I write may make some estimate of things by calculating one thing by another, so this leads them to other heads of trade to calculate from; as, first, the value of money, which bore some proportion, though I think not a full and just equality to the provisions, as follows:--silver was at 2s. 4d. per ounce, and gold at 2_l._ 5s. to 2_l._ 10s. per ounce; something less in the silver, and more in the gold than half of the present value. As for the rate of lands and houses, they bore a yet greater distance in value from what they produce now; so that indeed it bears no proportion, for we find the rent of lands so raised, and their value so improved, that there are many examples where the lands, valued even in queen Elizabeth's days at 20_l._ to 25_l._ per annum, are now worth from 200_l._ to 300_l._ per annum, and in some places much more. It is true, this advance is to be accounted for by the improvement made of the soil, by manuring, cultivating, and enclosing; by stocks of cattle, by labour, and by the arts of husbandry, which are also improved; and so this part is not so immediately within my present design; it is a large subject, and merits to be spoken of at large by itself; because as the improvement of land has been extraordinary great, and the landed interest is prodigiously increased by it, so it is capable of much more and greater improvement than has been made for above a hundred years past. But this I say is not my present design; it is too great an article to be couched in a few words. Yet it requires this notice here; viz., that trade has been a principal agent even in the improvement of our land; as it has furnished the money to the husbandman to stock his land, and to employ servants and labourers in the working part; and as it has found him a market for the consumption of the produce of his land, and at an advanced price too, by which he has received a good return to enable him to go on.
