Dr. William H. Welch, of Johns Hopkins 

 Uniyersity, is president of the conference. 



An attempt will be made to work out a 

 feasible three-year program for each of the 

 countries of the western hemisphere. Pre- 

 liminary organization is in charge of Paul 

 Popenoe. Headquarters of the conference are 

 at 411 Eighteenth Street, N.W., Washington,

DYE DIVISION OF THE AMERICAN CHEMICAL 

 SOCIETY 



The Dye Division of the A. C. S., which had 

 its inception first as a Dye Symposium then 

 as a Dye Section, is now a duly organized 

 part of the American Chemical Society. The 

 division is undertaking to carry on regular 

 and systematic work for the benefit of the 

 dye industry of America in general; and the 

 users of dyes, manufacturers of dyes, and dye 

 chemists in particular, laying, of course, its 

 especial emphasis upon the chemistry of dyes 

 and dyeing. 



It is the duty and the privilege of every 

 chemist in America, who is interested in the 

 chemistry, manufacture, or use of dyes, to 

 enroll himself as a member of the American 

 Chemical Society and its Dye Division, to 

 attend and participate in the semi-annual 

 meetings. The advantage will be mutual, 

 both to the members and to the industry. 



To enroll yourself in the division, write to 

 the secretary, and also inform him if you 

 have ready for presentation any paper on the 

 manufacture or application of dyes and inter- 

 mediates. Enclose the sum of $1.00 as dues 

 for 1920. The dues are for the expenses of 

 the division, consisting mainly of postage and 

 stationary. It is planned as soon as funds 

 permit, to compile and distribute a directory 

 of dye chemists who are registered in the Dye 

 Division of the A. C. S. 



The next meeting of the Dye Division will 

 be at the fall meeting of the American Chem- 

 ical Society, to be held in Chicago September 



7 to 10, 1920. At that time it is expected 

 that a number of dye concerns will come for- 

 ward with papers of intensive scientific 

 interest. 



There has been some considerable feeling in 

 the past that the concerns should keep all 

 their research work secret, and that none of it 

 could be revealed at such meetings without 

 detriment. However, since every research 

 laboratory turns out a large amount of work 

 which is of very great scientific interest to the 

 trade in general but may have no sjtecific 

 bearing on any process in particular, we may 

 expect that a large number of papers will be 

 presented of such a nature as to demand the 

 attention of every dye laboratory. 



Please plan to attend this meeting and in- 

 form the secretary of the title of any paper 

 pertaining to the dye industry that you will 

 have ready for presentation.

 The Federated American Engineering So- 

 cieties. 



The joint conference committee of the American 

 Society of Civil Engineers, the American Institute 

 of Mining and Metallurgical Engineers, the Amer- 

 ican Society of Mechanical Engineers, and the 

 American Institute of Electrical Engineers, acting 

 as the ad interim committee in accordance with 

 the authorization of the organizing conference held
