war will come global reconstruction. We can hardly shirk our leading part in that reconstruction. "Not only is there a need for greater numbers of chemically trained men in wartime, but there is a need for even a better quality of men. This is because the problems involved are much more serious.. For instance, in peacetime, a mistake by a poorly qualified chemist may cut someone's profit, but in wartime it may mean death to thousands of our men." I would call your attention to the fact that we as a nation are not over 10% into the war effort a t the present time. Right now there is no noticeable excess of chemically trained personnel. We have no chemical reserve at the present time except men who are not yet completely into war work. FRANKC. WHITMORE PENNSYLVANIASTATECOLLEGE Sr~m C o ~ ~ s PENNSYLVANIA oa

To the Editor: As regards chemistry being a critical field, I would remind you that there bas never been an excess of chemists except for a short period during the middle of the depression. I don't know whether you have read the comments of Senator Millard E. Tydings about the deferment of technically trained men. In writing him about these comments, I made the following remarks: "In peacetime, about 5000 chemists and chemical engineers graduate from our colleges and universities each June. These men are absorbed by peacetime industry by September. The only exception to this was in the very bad year of 1932 when about 900 were not absorbed until the next spring. This figure came from a survey by a committee of the American Chemical Society of which I was chairman. Of course, many of these 5000 young men each year go into many phases of Exit t h e Splash industry which might not be called strictly chemical, T o the Editor: but which require a chemical background. To prevent the splashing and noise resulting from "From the above facts and others, it appears that there has never been an excess of chemically trained the use of water aspirators to obtain evacuated condimen in the country.
