The situation most preferable for a plantation is the southern declivity of a hill, rather gradual than abrupt; or a spot that is sheltered by a wall, a bank, or any other means, from the blighting north winds which so frequently blow, during the spring months, in this island: but at the same time it is necessary to observe, that the plants must enjoy a free current of air; for if that be obstructed they will not prosper. CHAPTER IV. _Of its Culture, with a Description of the Worm that annoys it._ As the tobacco plant, being an annual, is only to be raised from seed, I would particularly recommend to such as mean to cultivate it, the greatest care in purchasing these, lest by sowing such as is not good, they lose, with their expected crop, the season. The different sorts of the seeds not being distinguishable, like the plants, from each other, nor the goodness to be ascertained by their appearance, the purchaser, till he has raised a supply from his own cultivation, must depend on the veracity of the seedsman; who may be also sometimes deceived, having nothing to rely on but the honour of the person who raised it: prudence therefore requires that he should apply to a person of character in that profession. In describing the manner in which the plant ought to be raised from the seed, as well as in the succeeding process, I shall confine myself (without regarding the methods usually pursued in Virginia or Maryland, which, from the difference of the climate, can be of little service here) to the practice of the northern colonies of America; as these are more parallel in their latitude to England. And there being even a difference between the climate of these and that of Great-Britain, to the disadvantage of the latter (I mean with regard to the cultivation of the tobacco plant) I shall minutely attend to this variation, and in the directions I give endeavour to guard against the inconveniences of it. These instructions shall likewise be given in plain and familiar terms, and not in a language that can be only understood by the Botanist or Gardener, that this Treatise may be of general use. About the middle of April, or rather sooner in a forward spring, (for the season must be attended to, as this plant will not bear forcing) sow the seed in beds first prepared for the purpose, composed of such soil as before described, mixed with some warm, rich manure. In a cold spring, regular hot beds would be most eligible for this purpose; and indeed the Gardeners of this country are persuaded, that the Nicotania cannot be raised in any other way; but as these are seldom to be found in the garden of the farmer, and as I am convinced that if the weather is not remarkably severe, they might be reared without doors, for his benefit I shall give the following instructions relative to their treatment.
