Excerpt from Contributions to Plant Physiology The work of this department has thus far been exclusively graduate work, so that all of our students are intellectually rather mature. The scarcity of opportunities for carrying on advanced work in plant physiology, together with the fact that numerous educational institutions offer opportunity for ele mentary academic courses in this and the related subjects, have made it appear undesirable to institute undergraduate courses here. Experience seems to show, furthermore, that the intellectual power of graduate students is greater among those who have migrated from one institution to another, than it is among those who have performed their undergraduate work in the same institution as that in which graduate work is undertaken. Whether a causal relation is mainly involved here is questionable, for the very fact of student migration generally bespeaks a serious purpose and a definite aim; but it is also undoubtedly true that student migration tends strongly to prevent and to obliterate provincial traits of men tal character, and to give to the student who has thus migrated one or more times a more extensive series of in terests and a deeper appreciation of relative values.
