The luxuriant soil of Louisiana is capable of of producing many articles even more lucrative than cotton, of which there is no immediate danger of creating an over supply. For some of them, there is a very large and increasing home consumption, as well as an active demand in other parts of the world that are open to our commerce. Of sugar, I have spoken already. Madder, silk, hemp, tobacco, may also be mentioned, as promising sure results to any who are disposed to try them. Under the impression that, in view of what I have already presented, the subject will be interesting to my readers, I shall venture to add a few words in relation to some of the above-mentioned articles.

Madder,[3] (rubia tinctorum,) the roots of a plant, which consist of several varieties. They are long and slender; varying from the thickness of a goose quill, to that of the little finger. They are semi-transparent, of a reddish color, have a strong smell, and a smooth bark. Madder is very extensively used in dying red; and, though the color which it imparts be less bright and beautiful than that of cochineal, it has the advantage of being cheaper and more durable. It is a native of the south of Europe, Asia Minor, and India; but has long since been introduced into, and successfully cultivated in Holland, Alsace, Provence, &c. The attempt to cultivate it in England, like that of Indian corn, has proved a complete failure. The English, for a long time, depended upon Holland for their supplies; but now large quantities are imported from France and Turkey, under a duty of two shillings sterling on the manufactured, and sixpence on the roots. The duties, formerly, were much higher.

The plant is raised from seed, and requires three years to come to maturity. It is, however, often pulled in eighteen months, without injury to the quality, the quantity only being smaller. It requires a light vegetable mould, that retains the greatest quantity of water and adheres the least to the tools. When the soil is impregnated with an alkaline matter, the root acquires a red color, in other cases it is yellow. The latter is preferred in England, from the long habit of using Dutch madder, which is of this color; but in France, the red sells at a higher price, being used for Turkey red die.

The Zealand or Dutch madder is prepared for market in a manufactured state; and is known in trade by the terms, mull, gamene, ombro, and crops. In some other countries, the roots are packed up promiscuously, and the article is sold by the quintal. The price of madder, like every thing else, is affected by the quantity in market, and ranges in France from its minimum 22, to 100 francs a quintal. It does not deteriorate by age. The quantity used in this country is very considerable—but nothing equal to that required in Great Britain. For the particular manner of cultivating madder, the reader is referred to an excellent essay upon that subject, from the pen of M. De Casparin, which was laid before the Academy of Sciences at Paris, and a prize awarded to its author.

The mulberry is grown with little difficulty in these latitudes, and therefore, silk may be produced in abundance, and rendered an article of domestic and commercial consequence. Plantations have already been commenced in several of the parishes, which will soon test the feasibility of the undertaking. A gentleman by the name of Vasseur, recently from France, has purchased land and made preparations to enter into that business, under many years of experience. In the parish of St. James, particularly, considerable attention is being paid to the culture of silk. It would be extremely gratifying to be able to lay the result of these experiments before the reader; but the necessary information is not at hand.

Hemp is raised in Missouri and Kentucky to some extent, as the quantities annually landed on the levee in New Orleans afford ample evidence. The demand for it will be good for many years, and the hint should not be neglected by the citizens of Louisiana, who possess the higher grounds, which are calculated for its production. When it is considered that this is a raw material of vast demand, which has heretofore been furnished from abroad, there can scarcely be any excuse for neglecting the culture, provided the profits be equal to those on sugar and cotton. The time may come, when even foreign nations will look to this republic for cordage and duck; at all events, we should not depend upon them for articles necessary for domestic purposes, and especially for those which may with propriety be classed "among the sinews of war."

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.
