Triumphs and wonders of the 19th century, the true mirror of a phenomenal era, a volume of original, entertaining and instructive historic and descriptive writings, showing the many and marvellous achievements which distinguish an hundred years of material, intellectual, social and moral progress .. . oll of paper is guarded against is a device in the shape of a short endless belt of rubber which passesover two pulleys and rests on top of the roll of paper. The paper is thenpulled from the roll as gently as the thread is pulled from the spool of asewing machine. The belt pushes the roll along at a speed equal to andsometimes a little greater than that of the stereotype cylinders. Hence, alltension is removed from the paper. From the stereotypers department, where they have been made in a fewminutes, come the plates of curved, bright metal. Passed to the pressmen,they are locked on the cylinders as fast as they can be handled. The rolls ofpaper have been placed in their proper positions. This accomplished, the men step back from the machine, the brakemanpulls the lever, and the giant press begins its work. Slowly its cylindersrevolve at first, but as headway is gained the rumble that accompanied thestart increases into a shrill shriek as the limit of speed is LITHOGRAPHIC PRESS. The paper rushes from its continuous rolls, is printed, folded, cut, andthrown out from the four outlets at a speed that would be over twice greaterthan that of any express train if it were confined to one roll. Every paperis just like every other one, perfect in every detail. When this has gone on for an hour, two hours, or however long it maytake to run off the editions, the monster press can be stopped in an the simple touching of a lever all its movement will cease before thecylinders can revolve five times, and they had been revolving two hundredtimes a minute before. The two wonders just described are confined to newspaper work. Thissame American fi
