thousand.  Finding it impossible, from the growing circulation of the paper, to supply the demand with the two six-cylinder presses printing from type, it was determined, early in the year, to stereotype the forms, so that duplicate plates could be used simultaneously on both.  The requisite machinery was introduced therefor, and on June 8, 1870, was put in use for the first time.  For nearly ten years the Herald was the only paper in Boston printed from stereotype plates.  In 1871 the average daily circulatian was eighty-three thousand nine hundred, a gain of nearly eleven thousand over the previous year.  On a number of occasions the edition reached as high as one hundred and twelve thousand.  On October 1 George G. Bailey disposed of his interest in the paper to the other proprietors, and retired from the firm.  In 1872 there was a further increase in the circulation, the daily average having been ninety-three thousand five hundred.  One issue (after the Great Fire) reached two hundred and twenty thousand, and several were not much below that figure.  The first Bullock perfecting-press ever used east of New York was put in operation in the Herald office in June, 1872; this press feeds itself from a continuous roll of paper, and prints both sides, cutting and delivering the papers complete.  On January 1, 1873, Justin Andrews, who had been connected with the Herald, as one of its editors since 1856, and as one of the proprietors who succeeded Mr. Bailey in 1869, sold his interest to his partners, and retired from newspaper life altogether.  Since that date, the ownership in the Herald has been vested in R.M.  Pulsifer, E.B.  Haskell, and Charles H. Andrews.  The circulation in 1873 exceeded one hundred and one thousand daily; in 1874 one hundred and seven thousand; in 1875 one hundred and twelve thousand; in 1876 one hundred and sixteen thousand five hundred.  On November 8, of that year, the day after the presidential election, the issue was two hundred and twenty-three thousand two hundred and fifty-six.  The two six-cylinder Hoe presses had given place, in 1874, to two more Bullock machines, and a Mayall press was added in 1876; the four were run to their utmost capacity on the occasion just mentioned, and the magnitude of the day’s work will be better understood when it is stated that between 4 A.M. and 11 P.M. fourteen tons of paper were printed and sold, an amount which would make a continuous sheet the width of the Herald two hundred and fifty miles long.  In 1877 a fourth Bullock press was put in use, and the Mayall was removed to Hawley Street, where type, stands for fifty compositors, a complete apparatus for stereotyping, and all the necessary machinery, materials, and implements are kept in readiness to “start up” at any moment, in case a fire or other disaster prevents the issue of the regular editions in the main office.
