various improvements, prominent among which were No. 18,640, Nov. 17, 1857; No. 25,199, Aug. 23, 1859 (re-issue No. 4,429); No. 84,627, Dec. 1, 1868 (re-issue No. 4,400); No. 113,769, April 18, 1871; No. 124,460, March 12, 1872; No. 131,217, Sept. 10, 1872. The first rapid printing press of the Hoe Company was set up in the office of the _New York Tribune_ in 1871, and its maximum output was 18,000 an hour. This marked the great era of rapid newspaper printing, and following it many further improvements, such as devices for folding and counting the papers automatically, have been added, until to-day the great Hoe Octuple Press, shown in Fig. 124, is the wonder of the Nineteenth Century. It prints 96,000 papers of four, six, or eight pages in an hour, or at the rate of 1,600 a minute, and these papers are not only printed, but in the same operation and by the same machine are cut, pasted, folded, and counted automatically. Fifty miles of paper of the width of an ordinary newspaper pass through it each hour from its several rolls. The machine weighs over 60 tons, and is composed of about 16,000 parts, and yet its touch is so deft, and its members so delicately and accurately adjusted that it does not tear the tender sheet as it flies through the machine--so fast that one-fifth of a second only is required to print a page.

PRINTS, CUTS, PASTES, FOLDS AND COUNTS NEWSPAPERS AT RATE OF 1,600 A MINUTE.] The latest development in the printing press has been in color printing, which has recently been introduced in the illustration of some of the largest daily newspapers. Such a press contains from 50,000 to 60,000 parts, and its cost is from $35,000 to $45,000. Collateral with the development of the printing press are three important branches of the art--stereotyping, paper making, and type setting.
