depend on Virginia and Maryland alone as its culture becomes more difficult, the price would rise so as to enable the planter to surmount those difficulties and to live. But the western country on the Mississippi, and the midlands of Georgia, having fresh and fertile lands in abundance, and a hotter sun, will be able to undersell these two States, and will oblige them to abandon the raising of tobacco altogether. And a happy obligation for them it will be. It is a culture productive of infinite wretchedness. Those employed in it are in a continual state of exertion beyond the power of nature to support. Little food of any kind is raised by them; so that the men and animals on these farms are badly fed, and the earth is rapidly impoverished. The cultivation of wheat is the reverse in every circumstance. Besides clothing the earth with herbage, and preserving its fertility, it feeds the laborers plentifully, requires from them only a moderate toil, except in the season of harvest, raises great numbers of animals for food and service, and diffuses plenty and happiness among the whole. We find it easier to make an hundred bushels of wheat than a thousand weight of tobacco, and they are worth more when made. The weavil indeed is a formidable obstacle to the cultivation of this grain with us. But principles are already known which must lead to a remedy. Thus a certain degree of heat, to wit, that of the common air in summer, is necessary to hatch the eggs. If subterranean granaries, or others, there

Moisture then, or external

fore, can be contrived below that temperature, the evil will be cured by cold. A degree of heat beyond that which hatches the egg we know will kill it. But in aiming at this we easily run into that which produced putrefaction. To produce putrefaction, however, three agents are requisite, heat, moisture, and the external air. If the absence of any one of these be secured, the other two may safely be admitted. Heat is the one we want. air, must be excluded. The former has been done by exposing the grain in kilns to the action of fire, which produces heat, and extracts moisture at the same time; the latter, by putting the grain into hogsheads, covering it with a coating of lime, and heading it up. In this situation its bulk produced a heat sufficient to kill the eggs; the moisture is suffered to remain indeed, but the external air is excluded. A nicer operation yet has been attempted; that is, to produce an intermediate temperature of heat between that which kills the egg, and that which produces putrefaction. The threshing the grain as soon as it is cut, and laying it in its chaff in large heaps, has been found very nearly to hit this temperature, though not perfectly, nor always. The heap generates heat sufficient to kill most of the eggs, whilst the chaff commonly restrains it from rising into putrefaction. But all these methods. abridge too much the quantity which the farmer can manage, and enable other countries to undersell him, which are not infested with this insect. There

is still a desideratum then to give with us decisive triumph to this branch of agriculture over that of tobacco. The culture of wheat by enlarging our pasture, will render the Arabian horse an article of very considerable profit. Experience has shown that ours is the particular climate of America where he may be raised without degeneracy. Southwardly the heat of the sun occasions a deficiency of pasture, and northwardly the winters are too cold for the short and fine hair, the particular sensibility and constitution of that race. Animals transplanted into unfriendly climates, either change their nature and acquire new senses against the new difficulties in which they are placed, or they multiply poorly and become extinct. A good foundation is laid for their propagation here by our possessing already great numbers of horses of that blood, and by a decided taste and preference for them established among the people. Their patience of heat without injury, their superior wind, fit them better in this and the more southern climates even for the drudgeries of the plough and wagon. Northwardly they will become an object only to persons of taste and fortune, for the saddle and light carriages. To those, and for these uses, their fleetness and beauty will recommend them. Besides these there will be other valuable substitutes when the cultivation of tobacco shall be discontinued such as cotton in the eastern parts of the State, and hemp and flax in the

western.

It is not easy to say what are the articles either of necessity, comfort, or luxury, which we cannot raise, and which we therefore shall be under a necessity of importing from abroad, as everything hardier than the olive, and as hardy as the fig, may be raised here in the open air. Sugar, coffee and tea, indeed, are not between these limits; and habit having placed them among the necessaries of life with the wealthy part of our citizens, as long as these habits remain we must go for them to those countries which are able to furnish them.

The weights, measures and the currency of the hard money? Some details relating to exchange with Europe?

Our weights and measures are the same which are fixed by acts of parliament in England. How it has happened that in this as well as the other American States the nominal value of coin was made to differ from what it was in the country we had left, and to differ among ourselves too, I am not able to say with certainty. I find that in 1631 our house of burgesses desired of the privy council in England, a coin debased to twenty-five per cent.; that in 1645 they forbid dealing by barter for tobacco, and established the Spanish piece of eight at six shillings, as the standard of their currency; that in 1655 they changed it to five shillings sterling. In 1680 they

sent an address to the king, in consequence of which, by proclamation in 1683, he fixed the value of French crowns, rix dollars, and pieces of eight, at six shillings, and the coin of New England at one shilling. That in 1710, 1714, 1727, and 1762, other regulations were made, which will be better presented to the eye stated in the form of a table as follows:

The first symptom of the depreciation of our present paper money, was that of silver dollars selling at six shillings, which had before been worth but five shillings and ninepence. The assembly thereupon raised them by law to six shillings. As the dollar is now likely to become the money-unit of America, as it passes at this rate in some of our sister States, and as it facilitates their computation in pounds. and shillings, &c., converso, this seems to be more
