Specimens of _tobacco_, the produce of seed imported from Cuba, have been exhibited in this market, which are very little, if any, inferior to the best from that island. These samples were raised by a gentleman who resides near Jackson, who took no extraordinary pains in the cultivation. The segars manufactured from them would pass, among good judges, for the best Havana. This planter is of opinion that he can very much improve the crops, by bestowing as much care upon them as is given to the same pursuit in Cuba, and there can be little reason to question his assertion. The Natchitoches tobacco stands higher abroad, particularly for snuff, than any other. This article is so well known in France, and many other places, that those who are engaged in planting it, boast that it requires no protective duties, as it will be quite able to take care of itself. The only drawback upon the cultivation of tobacco, in this state, is the worm, which begins its depredations in early summer. But much loss by this annoyance might be avoided, by forcing the plants in their early stage, in a hot-house, so that they might sooner be brought to maturity, and two clippings be made before the advent of the worm. The thin soil on lake Pontchartrain is found to be well adapted to the _vine_. Already, considerable progress has been made in its cultivation in that neighborhood, and grapes are abundantly furnished for the New Orleans market. There is no doubt that wine might be produced in abundance. _Indigo_, one of the oldest products of this state, has been superseded by the sugar cane. Whether the planter has found more advantage in the latter than in the former cultivation, can only be inferred from his continuing to pursue it; for the maxim, that trade will regulate itself, is nearly as applicable to agriculture as to commerce.
