From 1830 to 1860 the progress made in the mechanical department of the business was slow and unimportant in comparison with recent inventions. Cylinder presses came into general use for the printing of daily papers, but the weekly and monthly publications continued to use the primitive hand machines. The speed of press-work was still limited to a few hundred copies per hour, so that an extensive circulation could not be supplied even if there had been a demand for it. The white paper used was still made entirely of rags, and most of the material was imported from Austria and Italy. The cost of production was high, and few newspapers in the United States were published at a fair profit. The uncertainty of the financial returns from the business greatly retarded its development. Inventors found that their ingenuity would receive more substantial rewards in other fields, and editors and publishers were rarely practical men who could discover imperfections in mechanism and suggest improvements in their own shops. Throughout the first half of the century most of the improved methods of printing were developed in the establishments of book and job printers. There new presses and all new mechanical devices were first installed, and the newspaper followed, instead of leading, in the work of material progress in the art.

FROM THE NEW YORK EVENING POST OF DECEMBER 23, 1801.] To the New York Herald is generally credited the departure from old-time methods that resulted in the creation of newspapers devoted entirely to the publication of news, the reporting of the happenings of the world day by day. The innovation was not well received by the editors, who believed that the public cared more for opinions than a record of events. The new method proved popular, however, and the development of the newspaper from the personal journal and party organ dates from that time. The founder of the Herald and the new school of journalism spent money to obtain the news of the world ahead of the ordinary channels of communication. He established a system of special couriers, employed correspondents, and made the collection of reports of events of general interest a matter of first importance in the business of making a newspaper. Other editors followed the new movement slowly, and often with much doubt and hesitation, but those who stood still and refused to supply their readers with the news were in time compelled to go out of the business.
