Each of us Committee on Professional Training represent the is responsible for one of the more advanced courses in the department but this common interest in the elementary work brings us all in touch with the younger students and gives to the work a human interest and an intellectual stimulus which is difficult to attain where chemistry must be taught by mass production methods. Expensive of skilled personnel, yes, but this has been met in considerable part by a department organization that frees the teaching staff from the time-consuming care of equipment, preparation of the laboratory, and the general mechanics of laboratory management. That was an idea taken over from Dr. Alexander Smith at Chicago and later at Columbia when he turned over the laboratory "business" to Dr. Thomas B. Frees. Our department has an Assistant Director, who had majored in chemistry and has made laboratory management her profession. This means that the teaching staff is relieved of this hehind-the-scenes work and has made possible the continuation of some research with our fairly heavy teaching schedules. For.more than twenty years Mount Holyoke has had a system of general examinations which are given to seniors a t the end of their college course. This is an all-day examination which covers all the work of the maior subiect. Althoueh the denartment has never felt Vacuum Spectrograph satisfied .with the types of examination which we have given, nor with the results, for that matter, yet the maximum number of hours which our curriculum allows examinations are undoubtedly valuable to the students in one department.

is a very real value also to the members of the department in that the direction of honors problems and Masters theses keeps us alert and interested in productive research. The department has developed over t h e years a method of advising major students in their junior and senior years in the election of courses, which is again rather expensive of time but is possible where we have had from fifteen to twenty-five major students from each class. Insteadof delegating the advising to one or two members of the department, we get together as a group around the library table and twice a year discuss with each student individually her plan ofwork.

t o the department and the college cannot be so easily evaluated. According to our plan of work the assistant gives half of her time to department work and half to graduate study. Four graduate seminars are offered-in thermodynamics, advanced physical, advanced organic, and physical chemistry applied to organic problemsand students very frequently fulfill a part of their requirement by advanced work in a related department, most frequently physics. The course in thermodynamics is required of all Master's candidates and ordmarily they take two of the other courses. The content of these courses varies somewhat from year to year and includes recent work and literature search whenever possible. The major portion of the graduate student's time is given to experimental work on her special problem, the report of which is presented in the form of a thesis which must be approved by the department and the Graduate Committee of the college. The requirements are usually completed in the two years of half-time work. At the end, the candidate must pass a written examination in her graduate courses and an oral one on her thesis. The research interests of the department include both synthetic organic and physical chemistry, together with a combination of the two fields of work. The study of hydantoin derivatives extended over many years and a number of papers with student collaborators have been published. Studies in the absorption spectra of organic compounds were begun in the department in 1914. This type of physical measurement was undertaken in order that we might use it in connection with the synthetic organic research and thus give to the young graduate student as varied a training as possible, and at the same time that we might become skilled ourselves in

the use of a new physical tool which gave promise of wide application. As the work progressed it seemed advisable to undertake a systematic study of the characteristic absorption of a single chromophoric group, the carbon-carbon double bond. This investigation necessitated the preparation of very highly purified hydrocarbons and examination of their absorption spectra in the near ultraviolet with the quartz spectrograph and later in the far ultraviolet with the fluorite vacuum spectrograph. This extensive study of simple hydrocarbons has continued for almost twenty years and has been carried on as a group research project in which an organic chemist, a physicist, and two physical chemists have collaborated. It offered particularly favorable problems for honors and graduate s~udentsand our library has more than fifty graduate theses and honor's papers which report work in this field. In addition, there have been thirty-five publications by members of the staff and student collaborators which cover differentphases of the investigation. Group research in a small department adds much to the zest and interest of the work. Research develops slowly with the brief time a t one person's disposal when so much time and energy must go to teaching, but i t can repreaent a worth-while contribution to science if there can be the cooperative effort of an enthusiastic group. As is so often true, when a research project gets under way it is then possible to obtain financial support and this investigation has been aided greatly by grants from the National Research Council and the Rockefeller Foundation. The absorption spectra of .organic compounds in the far ultraviolet wave was almost completely unexplored and new techniques and new methods had to be developed. Equipment for this work in our laboratory was made possible through these grants. This theoretical investigation of the hydrocarbons was discontinued during the war for a group research project in organic chemistry in connection with the government's antimalarial program. The laboratory in which we work is old and far from adequate for our needs. It is a serious fire hazard, as fireproof buildings were not deemed necessary or possible when this was built in 1892. Our department library and spectrographic laboratories are housed temporarily in the near-by fireproof biological laboratory. The physics wing of a new physics-chemistry building was built in 1931 and this gave us additional muchneeded space in the old building. But the number of students taking chemistry has grown tremendously and the scope of the work increases constantly. Plans have been drawn for the completion of the building and it is hoped that this may not be too long delayed. Since its beginning in 1837 Mount Holyoke has always had a decidedly scientifictrend in its curriculum. It is indeed remarkable that a t that time seven sciences out of a total of twenty-three subjects were required of all students before graduation. Mary Lyon was herself an early teacher of chemistry and introduced indi-
