goodly uumber of them having all the desired 

 advantages of indigo and others equally- 

 numerous, possessing highly prized advantages 

 which indigo lacks. All of these good ones 

 are free from certain disadvantages of indigo 

 and, what is more important, their shades 

 cover every tint in the rainbow satisfactorily 

 except the reds and those can not much longer 

 elude the searchers. Some day a new blue 

 dye may result from these researches or from 

 other researches growing out of them and 

 indigo will no longer be king. In still other 

 directions the chemical study of indigo has 

 been fruitful. By proceeding along lines sim- 

 ilar to those of the 1897 method, but dis- 

 placing the nitrogen by sulfur, an entirely 

 new line of materials has been made accessible 

 through chemical research and no man is wise 

 enough to place the limit upon the directions 

 and the extent that chemical ingenuity and 

 research will ultimately go in this one very 

 small field of chemical effort, which requires 

 and draws upon all the sources of chemical 

 knowledge we have. The possibilities seem 

 limitless. 



True research must be intentional and in- 

 tensive. We must really seek if we would 

 find. We must really knock at the doors of 

 the secret chambers of knowledge, if they are 

 to be opened to us. We must have imagina- 

 tion, it is true, but we must have more than 

 that. There must be the foundation of sound 

 education, and the ability to extend it to em- 

 brace new and unexpected knowledge, and 

 apply this in turn as we progress upwards. 



To fit a man for research in cheinistry or 

 any other science, many things must be ac- 

 complished before the candidate is ready to 

 take his first advanced step. Many methods of 

 procedure have been suggested, and some heat 

 of argument generated; but all agree that 

 education which produces real practical knowl- 

 edge is absolutely essential. All agree, also, 

 that the person to be prepared must be a likely 

 subject; and that energy and time should not 

 be wasted on those who do not show that they 

 possess certain necessary qualifications. I think 

 that it will also be generally admitted that the 

 teacher himself should not only have great 

 attainments, but must also possess the rare 



quality of being able to transmit knowledge 

 in such a way that it will be truly absorbed by 

 the pupil and form part of him. One of the 

 greatest mathematicians I have ever known 

 was about the poorest teacher. He knew but 

 could not impart. The future of the world, 

 therefore, depends in a very large degree, on 

 the teacher in the school and on the professor 

 in the college. They have an opportunity to 

 mold the world, which many of them thor- 

 oughly appreciate. Alas, in most instances, 

 the consciousness of work well done is about 

 their only reward. Some day, and I hope not 

 a very distant one, it will be generally recog- 

 nized that, like other laborers, they are worthy 

 of their hire, and their compensation will more 

 nearly approximate the value of the work 

 done. When that happy day arrives, they 

 may experience a little less of the satisfaction 

 of sacrifice, but they will have other comforts 

 and hopes which will more than make this up 

 to them and to their families. Like others 

 before me, I advise the people of this country 

 that they can make no better investment than 

 one liberal enough to cause the teaching pro- 

 fession to attract not only those whose high 

 sense of duty leads them to embrace it at a 

 sacrifice, but also those who can not afford to 

 make the sacrifice, however anxious they may 

 be to do so. Men preparing for research 

 must have the best men in the country to 

 gTiide them, and it is not fair to expect these 

 men, as so many have done in the past, to live 

 the narrowing life of poverty. Neither is it 

 wise. 



There are a few foundations specifically 

 provided for chemical research, such as the 

 Warren Fund of the American Academy of 

 Arts and Sciences, the C. M. Warren Fmid of 

 Harvard University, and the Wolcott Gibbs 

 Fund of the National Academy of Sciences. 

 There are a number of foundations for pro- 

 moting research generally which have in- 

 cluded chemical research within their fields, 

 such as the Bache Fund of the National 

 Academy of Sciences and the Elizabeth 

 Thompson Science Fund. The Rockefeller In- 

 stitute for Medical Research fosters chemical 

 research contributory to its main object, the 

 Carnegie Institution of Washington supports
