The public schools, designed for the general and gratuitous dissemination of knowledge among all classes, have not only increased in number but have generally outstripped those of the higher order, by seizing at once upon all the improvements which the experience of teachers in other parts of the country, and the world, has from time to time suggested. Mere innovations rather hinder than advance the progress of education. But the simplest suggestion of an enlightened experience and a sound judgment, such as are brought to bear upon this great interest throughout the whole of the northern and eastern States, is entitled to the profound regard of the Southern philanthropist, whose aim and ambition it should be, to make the most of every facility and to be no whit behind the older, but not more wealthy sections, in any thing that can promote the moral and intellectual power of the masses of the people.

The climate of Louisiana is hot and moist. In the neighborhood of the marshes, and in the summer season, it partakes of the unhealthy character of nearly all tropical climates. Diseases of the lungs, however, and other complaints so prevalent at the north, are scarcely known; and to many, the quick consuming fever which finishes its work in a few days, may be considered but a fair offset to the slow but sure consumption, which flatters its victims with the semblance of life and hope, while dragging them through its long and dreary labyrinths, to the chambers of death.

This climate is favorable to almost all the productions of the tropics. The sugar, the cotton plant, the orange, the lemon, the grape, the mulberry, tobacco, rice, maize, sweet potato, &c., &c., flourish in rich abundance, and some of them attain to a luxuriance of growth scarcely known in any other part of the world. Sugar and Cotton are the two great staples. The former is confined chiefly to that tract, which, by way of distinction, is called "the coast," lying along the shores of the Gulf, and the bayous of the Mississippi.

The average sugar crop of the whole state, is now about 180,000 hogsheads. That of cotton, for the last year is not ascertained, but the amount produced in the whole valley of the Mississippi, sent to New Orleans for export in 1843, was 1,088,000 bales. Owing to the large extension of the cotton growing districts, and excessive competition in its manufacture, the cultivation of cotton yields less profit than it formerly did, and there seems to be no substantial reason why it should not, in some degree, give place to sugar, at least until the latter can be furnished in sufficient quantity to supply the domestic consumption. Under the ordinary increase of population, the utmost exertions of the cane planters will hardly arrive at such a result, in half a century to come.

While on this subject, it will not, I trust, be deemed irrelevant or officious, to place before the reader the suggestions of an intelligent gentleman of New Orleans, in regard to the present mode of cultivating and manufacturing sugar. He observes that in order to carry on the business to advantage, and compete favorably with those already established, a large capital is required, since in addition to the ground to be cultivated, and the hands to be employed in the field, expensive mills and machinery must be set up, and kept in motion, with a large number of laborers in attendance. Consequently no man in moderate circumstances can undertake this branch of business, as it is now conducted. To obviate this difficulty, and extend the cultivation and manufacture of this important staple, he proposes a division of labor and profit, like that which prevails in the grain growing and milling regions of the north. The farmer sells his wheat, at a fair market value, to the miller, or pays him a stipulated percentage for grinding and bolting. In the same manner might the business here be divided into two distinct branches. The planter might sell his cane to the miller, or pay him the established price for converting it into sugar and molasses. This would enable men of comparatively small means to undertake the cultivation of the cane, who now confine themselves to cotton, and thus relieve the larger cultivators of the latter staple from the dangers of over production.

Casting our eyes back to no very distant period, and noticing the small beginnings of our early planters of cotton, the reader will pardon the introduction of a trifling anecdote. During the year 1784, only sixty years since, and therefore within the memory of many now living, an American vessel, having eighty bales of cotton on board, was seized at Liverpool, on the plea that so large an amount of cotton could not have been produced in the United States. The shipment in 1785 amounted to 14 bales, in 1786 to 6, in 1787 to 109, 1788 to 389, in 1789 to 842. An old Carolina planter, having gathered his crop of five acres, was so surprised and alarmed at the immense amount they yielded, which was fifteen bales, that he exclaimed "well, well—I have done with cotton—here is enough to make stockings for all the people in America!" The cotton crop of the United States for 1844 was 2,300,000 bales.

The fluctuations in the foreign cotton market, within a few years past, have produced, among scientific agriculturalists and experienced planters, no little speculation upon the course which a due regard to their own interests requires them to pursue. It is not to be wondered at, that in a country so vast, so luxuriantly fertile as ours, and teeming with the most enterprising and industrious population on the face of the earth, the strict relations of supply and demand should be occasionally disturbed in some of the many abundant productions of the soil. It is always a difficult problem to solve, especially where the field is very large, and the producers many, and constantly increasing. In attempting to meet it, the first question to be answered is, does the present supply greatly overreach the present demand?

An intelligent writer in Hunt's Merchant's Magazine for October, 1844, Henry Lee, Esq., has placed this subject, so far as he has there pursued it, in a very clear light. He commences by stating that "the consumption of cotton in Europe, other than the production of America and India, is too insignificant to have any important bearing upon prices." He goes on to show that the value placed upon the article at present, is quite sufficient, and that the advantage it gives to the manufacturer of New England, whose operations are vastly increasing, renders him a successful competitor to those of Great Britain; and nothing but an inflated currency, or imprudent speculations can produce an advance. And any advance so procured must inevitably be followed by a ruinous reaction. He shows that, through the agency of the British manufacturers, and the exporters of their goods to countries beyond the Cape of Good Hope, a considerable quantity of American grown cotton had been sent to those regions, in the form of manufactures and twist, over and above the amount of Indian grown cotton consumed in the factories of England. This simple fact, which is demonstrated as clearly as figures can speak, completely nullifies the importation of cotton from that quarter.

The proportion of raw cotton, other than the produce of the United States and India, used in the manufactures of Great Britain, is very small, and constantly diminishing in quantity. After producing statistical evidence, Mr. Lee arrives at the satisfactory result that the consumption of cotton from the United States and India, is as ninety-four to one hundred, leaving, for all other sources of supply, only six per cent. With such a ratio as this, and the competition constantly declining, it is manifest that we have nothing to fear from rival producers.

The delicate enquiry now arises, can the American planter sustain himself under existing prices? Or, can he, by the exercise of better economy, make his labors more productive? It seems to me, if it will not be presuming too far to offer the suggestion, that there should be an understanding between the larger and more intelligent planters, in relation to these points, and that they should, for their own individual and collective interests, consider, whether it would not be better partially to restrain the cultivation of this staple, rather than permit it to increase beyond the known and certain demands of commerce. The question increases in importance, as the cotton growing region enlarges, by the admission of "the lone star" into the constellation of Freedom. While it secures to the United States forever almost the entire monopoly of production, it puts it in her power, by a judicious combination among her great producers, to command a fair compensating price for cotton. Without some such combination, or, which is equivalent to the same thing, a prevailing disposition on the part of the planters, rather to wait for a demand than to anticipate, or endeavor to create it, there will always be a surplus stock in the market, which, however insignificant, will affect the price of the whole crop.
