Rh becomes for life a reader, and to some extent, a purchaser of books. The value of the school-books manufactured in the United States annually, has been estimated at fifteen million dollars. Of Webster's Spelling-Book alone, thirty-five million copies have been sold, and a million copies are printed every year. If printing were deprived of the support it receives from public schools, there would at once follow a noticeable decrease in the production of printed matter, and a corresponding decrease in the number of readers and book-buyers.

Railroads, steamboats and package expresses are aids of as great importance. The New-York daily newspaper, printed early in the morning, is sold within a radius of three hundred miles before sunset of the same day. Newspapers now find hundreds of eager purchasers in places where they would not have found one in the days of stage-coaches. The benefits of cheap and quick transportation are also favorable to the sale of books. A bookseller's package, weighing one hundred pounds, will be carried from New York to St. Louis, on the Mississippi, within sixty-five hours, at an average expense of three dollars. When there was no railroad from St Louis to San Francisco, the overland charges on one hundred pounds of books were one hundred dollars.

The greatest legislative aid that printing has received is through the facilities which are furnished by post-offices and mails. They create readers. Weekly newspapers are now sent, for one year, for twenty cents, to subscribers in the most remote corner of the Union. Books are sent three thousand miles at the rate of one cent per ounce.
