Cobbett's book on the subject, from a conviction that it is the best essay that has ever been published on the culture and use of this valuable plant. It will be seen, however, that we differ from Mr. C. in the distances in which the plants are to be set, and in the manner of forming the ridges. He forms his ridges by four gathering furrows, by which the ridges are each about 4 feet in breadth. We propose to form the ridges by two gathering furrows, and at the distances of 30 inches. In England, the plan we recommend is generally pursued, and the ridges are usually but 27 inches wide. (To be continued.) FROM NILES' WEEKLY REGISTER. _Cotton, Rice, Tobacco, Sugar, Wine._ The National Intelligencer informs us that in New York 133 bushels of Indian corn have been gathered this year from _one acre_; and 714 bushels of potatoes from one acre. This has led to the following statistical facts. COTTON.--In 1817 the export of cotton from the United States was (85,649,328_lbs._) more than eighty-five million. One acre yields, at a moderate estimate, 250lbs. of clean cotton. The whole export, therefore, is the product of only 535 square miles: this is less than the 108th part of Georgia, and less than the 520th part of the cotton regions of the U. States. RICE.--The maximum export of rice was 73,329 tierces, (in 1790,) or (43,997,400_lbs._) nearly forty-four million pounds. This, on an average crop, is the produce of only sixty-five square miles, which is less than the 440th part of South Carolina, and less than two-thirds of the District of Columbia. TOBACCO.--The maximum export of tobacco was 12,428 hogsheads, in 1791. A hogshead is about one thousand weight; and, on average, one acre will yield one hogshead. The export, therefore, was the product of about 176 square miles, which is less than the 363d part of Virginia. Each of the 97 counties of that state contains, on an average, more than 659 square miles, viz: more than three times the quantity of land which furnished the above export. SUGAR.--Such is, generally, the fertility of the equinoctial regions of America, that all the sugar consumed in France, estimated at twenty million kilogrammes, (about 54,000,000 pounds,) may be produced on an extent of 7 square leagues, which is not equal to one-thirtieth part of the smallest department of France. WINE.--About 1,600,000 arpents, or 1,350,400 acres, are in France employed in the culture of the vine. The value of the annual product is about 100,800,000 dollars, at about twenty cents a gallon. In 1790 Bordeaux alone exported more than fifteen million gallons of wine. The 1,600,000 arpents are less than one 80th part of France, and less than one 20th part of Pennsylvania. The value of the annual produce of these five interesting articles, may be thus estimated:
