causes Avoukl also seem to l)e in order. Furthermore, " the question as 

 (() whether inrophosphates will induce a hypersensibility and thus in- 

 crease the activit}^ of pathogenic organisms should be investigated." 



The importance of this discovery as a contribution to our knowledge 

 regarding cotton-seed meal as a feeding stulf will be generally recog- 

 nized. P)ut beyond this the study will make possible and suggest a 

 wdiole train of studies upon various ingredients of feeding stuffs in 

 their relation to the animal organism. The desirability of investiga- 

 tions starting out from this point of view has been previously re- 

 ferred to, and is illustrated by several studies now in progress. 



The session of the Graduate School to be held this summer at the 

 Iowa State College bids fair to be one of unusual interest in a number 

 of respects. It offers an attractive program of advanced study in a 

 variety of subjects, and is held in a typical region, at one of the best 

 equipped agricultural colleges in the country. 



This is the fourth session of this school, held under the auspices of 

 the Association of American Agricultural Colleges and Experiment 

 Stations. The undertaking is cooperative between the association 

 and the institution at which the sessions are held, and is designed to 

 furnish facilities for a brief period of advanced study in the science 

 of agricidture Avitli special reference to the methods of investigating 

 agricultural problems and teaching agricultural subjects. The first 

 session Avas held at Ohio State University in 1902, the experiment 

 being so successful that a continuance of the school seemed desirable. 

 Provision was therefore made for its continuance b}^ the association, 

 the plan being to hold sessions every two years. The second session 

 took i)lace at the University of Illinois in 190G, and the third session 

 at Cornell University in 1908. 



With each succeeding session this school has assumed increasing 

 importance as an agency for study and for meeting the leaders in 

 agricultural instruction and investigation. The attendance has in- 

 creased steadily, that at the last session being one hundred and sixty- 

 four students and seventy-eight lecturers. The enthusiasm has run 

 high, and the spirited discussions and personal contact have served to 

 make the time both inside and outside the class room very profitable. 

 The change of instructors each week brings a new lot of men upon the 

 scene, and has the effect of keeping up the interest throughout the 

 session. To instructors and hearers alike the sessions have been 

 stimulating and helpful, as well as informational, and to the younger 

 assistants entering agricultural college and experiment station work 

 the schools have afforded an exceptional opportunity for broadening 

 their grasp and coming to know" many of the prominent men in these 

 lines of work.
