Air. Charles Joly, of Paris, is doing inestimable service to the French people, by keeping them informed of what the rest of the world is doing, and by which they may profit. An address of his on the subject cited, before the Societe Nationale et Central d"orticulture de la France, has just been issued in pamphlet form, which shows that while the business in Paris, Nantes and Bordeaux at one time almost controlled the world, these cities now have powerful rivals in the United States, Australia and Brazil. Steam has revolutionized the fruit trade, and Mr. Joly says that pineapples from Florida are sold in the streets of London at the same price that first-class apples bring. New Orleans comes in for a good share of favorable notice - "New Orleans, where its numerous languages, as well as its products, furnish the best living example of what happened at the destruction of the Tower of Babel." The address is filled with statistics of the American fruit trade, given in detail, and is profusely illustrated by representations of American fruit peelers and the various first-class appliances by which Americans dry and prepare fruits.
