346 MEMOIR OF DANIEL TREADWELL. 



Presses Avere also sent to Mr. Isaac Ashmead, of Philadelphia, for the American 

 Sunday School Avork, and with them went two of Mr. Treadwell's most efficient 

 female assistants, one of whom soon after became .the wife of one of the most 

 eminent printers in the city. In 1827 and 1828 presses were put in operation in 

 Washino-ton and Baltimore ; these were all for book-work. It was first used for 

 newspapers in 1829, in printing tlie Boston Daily Advertiser, and soon after 

 adopted in New York for the same purpose. Many of these presses were con- 

 structed by Mr. Treadwell in Boston, and also the steam-engines and other machin- 

 ery for putting them in operation. At the same time he was directing the nail 

 manufactory at the Mill-dam. 



Notwithstanding this pressure of mechanical employment, he found time to 

 edit, with the aid of Dr. John Ware and Prof. J. W. Webster, " The Boston Jour- 

 nal of Philosophy and the Arts." The object of this work, according to the pro- 

 posals issued in 1822, " is to render accessible to the American public the various 

 and important information which is constantly communicated to the European 

 world through the transactions of their learned societies and their scientific jour- 

 nals," and also to publish original articles relating to American science. The first 

 number was issued in May, 1823, containing about one hundred pages, and was 

 followed by others, once in two months, (the first volume being printed upon the 

 Treadwell Power Press,) until December, 1826, when the patronage no longer war- 

 ranted its continuance. This want of patronage " the editors feel themselves 

 warranted in attributing to the peculiarity of the public taste in regard to works 

 of this kind generally, rather than to the individual character of the papers which 

 they have published, from the fact that the selected articles, which comprise 

 the greater part of this journal, were written by men most celebrated for genius 

 and attainments in Europe, and on subjects that have occupied a great share of 

 the attention of the scientific world during the progress of this publication." 

 That the journal deserved patronage, the selected articles fully prove. Its original 

 articles by Dr. Ware, Mr. Treadwell, and others, are interesting and valuable con- 

 tributions to science. 



The manufacture of presses was continued until the year 1829. Mr. Treadwell 



says : — 



" Being from this time engaged in other pursuits, I made no efforts to alter or improve 

 the plan of the ])rcss. Others soon came in witli machines made all of cast-iron, more compact 

 in form, and somewhat more rapid in their operation. These were preferred to my machines ; 

 and, as the printers ahout this time enlarged the size of their paper, my early presses were 

 incapable of working it, and were necessarily given up."
