The faculty iiuniberetl GO, in tulditioii to IS speakers at the special 

 sessions and conferences. It included 19 officers of the United States 

 Department of Ajrriculture, 25 members of the faculty of Cornell 

 University and 7 members of the staff of the New York Station, and 

 17 professors and experts from ten other agricultural colleges and 

 experiment stations, besides the United States Commissioner of 

 Education, a representative of Teachers College of Columbia l^ni- 

 versity, and the New York State Commissioner of Agriculture and 

 the State P^ntomologist. 



In addition, lecture courses and seminars w^ere offered by Dr. C. B. 

 Davenport, of the department of experimental evolution of the Car- 

 negie Institution: Director A. D. Hall, of the Rothamsted Experi- 

 mental Station ; Prof. L, B. Mendel, professor of physiological chem- 

 istry in the Sheffield Scientific School of Yale University, and Prof. 

 Dr. N. Ziintz, professor of animal physiology in the Royal Agricul- 

 tural College of Berlin, which attracted particular attention. So 

 great was the interest manifested in these courses that not mfre- 

 quently the rooms assigned proved inadequate. Dr. Davenport gave 

 five lectures and a seminar in the poultry husbandry course, the sub- 

 jects of the lectures being : Origin of Domestic Fowl, Characteristics 

 of Poultry, (jeneral Principles of Heredity, and Application of 

 Princij^les of Heredity to the Breeding of Poultry (two lectures). 

 Director Hall had the same number of lectures in the agronomy 

 course, his lectures taking up Special P^ffect of Fertilizers upon the 

 Character and Composition of the Crop, Sj^ecial Effect of Fertilizers 

 upon the Reaction and Texture of the Soil, and General Discussion 

 of the Theory of Fertilizers in Relation to the Soil and the Plant. 



Unusual interest centered around the course in biochemistry. This 

 course w^as offered for the first time and proved exceedingly popular 

 and profitable, and may be sunnnarized as an example of the 

 advanced grade of work offered by the school. Following an intro- 

 ductory lecture by Dr. C. F. Langworthy, of this Office, on Physio- 

 logical Chemistry in Relation to Animal Nutrition, the remaining 

 four lectures of the first week were given by Dr. A. L. Winton, of 

 the Bureau of Chemistry of this Department, who took \\p the Micro- 

 scopical Methods for Detecting Adulteration in Feeding Stuffs. Dr. 

 Winton outlined the technique of such microscopical work and (bs- 

 cussed methods showing in detail hcnv it is possible to identify 

 adulterants by differences in their structure as shown by the micro- 

 scope in comparison with the standard food materials. In the weekly 

 seminar opportunity Avas given for demonstrating in greater detail 

 his methods and their application. 



Dr. Mendel gave five lectures and two seminars during the follow- 

 ing week. The first of the lectures discussed the Chemical Processes
