During the forty-two years that have elapsed since the first illustrated newspaper was founded, there has never been any long interval of peace. War of some kind, big or little, has broken out, like a volcano, on some part of the earth's surface, and kept the Argus-eyed newspaper editor on the alert. From Alma to Tel-el-Kebir and the desert warfare of the Soudan, there has been a succession of conflicts, with only a short interval of a few years between; so that the food on which picture newspapers thrive best has been abundantly supplied, and this remarkable offspring of the printing-press has consequently increased and multiplied, and is now found in every corner of the earth, 'from China to Peru.' The reader may form some idea of the magnitude of the operations in connexion with illustrated journalism when I state that at the marriage of the Prince of Wales the _Illustrated London News_ of that week consisted of three sheets, and 930,000 sheets were printed of that issue in one week. These sheets, if placed side by side, would cover 660 miles, so that, as they were printed on both sides, they represent a printed surface of, after deductions for margin, more than 1115 miles in length. Nearly eighty tons of paper and twenty-three hundredweight of printing-ink were used in the production of that number. Larger quantities have been printed of some issues, but the production was spread over a longer period of time. 930,000 sheets is the largest quantity ever printed _in one week_. It will thus be seen what an amount of business this represents to the paper-maker, the ink-maker, the wood-draughtsman, the engravers, the electrotypers, the compositors, printers, machine-men, roller-makers, warehousemen, and the numerous other workers in a newspaper printing-office.
