I'O REWORD 3 



of the thing sought for, and new researches are begun with definite 

 ends in \'\e\\. Thus it has come about that the communication 

 engineer has become an original investigator and is extending the 

 boundaries of human knowledge and supplementing the advances of 

 pure science to find solutions for his various and sundry problems. 



Hence, while well equipped physical and chemical laboratories are 

 still a necessary part of the communication engineer's equipment, he 

 is equally active in pushing his investigations in many other direc- 

 tions. Questions involved in the making of proper rate schedules and 

 adequate fundamental plans for new construction are originating 

 profound researches in such fields as political science, psychology and 

 mathematics. A casual examination of recent technical literature 

 dealing with electrical communication would show articles which 

 touch upon almost every branch of human activity, which we designate 

 as science. 



With this intense and growing interest in the proper application of 

 scientific methods to the solution of the problems of electrical com- 

 munication, it is natural that a widespread desire should have arisen 

 for a technical journal to collect, print or reprint, and make readily 

 available the more important articles relating to the field of the com- 

 munication engineer. These articles are now appearing in some 

 fifteen or twenty periodicals scattered throughout the world and in 

 the majority of instances receive their first and last printing in these 

 widely separated mediums. The need already felt for such a journal 

 will grow keener as new developments extend the scope of the art and 

 the specialization of its engineers of necessity increases. It is hoped 

 that the Bell System Technical Journal will fill this need, and 

 as implied above, it is intended that the range of subjects treated in 

 the Journal will be as broad as the science and technique of electrical 

 communication itself. 



While many of the articles which will appear in the Journal will 

 be original presentations of some phase of the research or develop- 

 ment or other technical work of the Bell System, it is not intended 

 that the Journal should be the sole means by which this work is 

 presented. Just as in the past, original articles and papers will con- 

 tinue to be presented before various societies and in different technical 

 and non-technical magazines. Moreover, the Journal will reprint 

 articles on important research and development work in the communi- 

 cation field generally so that the results of such work may be given 

 greater publicity and become of greater value to communication 

 engineers.
