print and fold ninety thousand four-page Heralds in an 

 hour. This is, to the mind which is not versed in the 

 problem of rapid printing, a feat which makes Aladdin's 

 lamp an old woman's fable. Ninety thousand per hour 

 means fifteen hundred copies per minute, or twenty-five 

 copies for every second ticked off by the clock hi 

 Trinity's steeple. 



"This press will print, cut, paste, fold, count, and 

 deliver 72,000 eight-page Heralds in one hour, which is 

 equivalent to 1200 a minute and twenty a second.

"It will print, cut, paste, fold, count, and deliver com-

 Heralds an hour, which is at the rate of 400 a minute, 

 or very nearly seven a second.

 have found all about how to put a harness on electric-

 reach its limit in the printing-press. But for the present 

 this new press marks high- water mark. 



"The new press has a well-nigh insatiable appetite

 rolls at the same time, one roll being attached at either 

 end of the press and the third suspended near the centre. 

 Each roll is sixty-three inches wide, or twice the width of 

 the Herald. When doing its best this press will consume
