REPORT OF THE DIRECTOR. 15 
«charge of an examination of some of the more interesting and 
important materials there exhibited. This investigation. was 
made in accordance with the purpose of the World’s Columbian 
Commission, which was to make the Fair educational and to 
provide that its influence should continue after the Fair 
itself should end. Probably no other occasion has offered such 
an opportunity for comparison of materials used for the nutrition 
-of man. Certainly none has been so favorable for collecting 
‘specimens of food materials which are most interesting to us in 
the United States. An examination of cereal grains was made 
«under the direction of Professor Wiley, Chemist in the U. S. De- 
partment of Agriculture. The prepared food products as such, 
including especially the animal foods, were assigned to myself. 
By the courtesy of the authorities of the University of Chicago, 
the use of the chemical laboratory-of that institution was given 
for the investigation. In ogder to save the expense of apparatus 
and the time required for preparing it, the trustees of the Storrs 
Station authorized the use of its material for the purpose, and 
more than a ton of packages of apparatus and chemicals was 
‘shipped from Middletown to Chicago and used in the investiga- 
tion. Mr. Woods, the Vice-Director of the Station, assumed for 
a time the immediate charge of the analyses. Messrs. H. B. 
“Gibson, H. M. Smith, F. W. Frost, A. E. Loveland, and H. M. 
Burr, who had been previously connected with the work of the 
Experiment Station or with that of the chemical laboratory of 
Wesleyan University; and Dr. C. F. Langworthy and Mr. E. L. 
Sturtevant, who have since become associated with the chemical 
laboratory, and Mr. O. S. Blakeslee of the physical laboratory, 
accompanied me to Chicago to share in the work. The services 
-of a number of other gentlemen were secured so that, all told, 16 
chemists, representing 12 American and foreign colleges and 
universities, were occupied there for a longer or shorter time 
during the summer. Somewhat over 600 specimens of food 
materials were collected. The analyses were made, so far as 
possible, in Chicago during the Fair. At its close the work was 
transferred to Middletown, where it has been continued with the 
aid of the Station and of Wesleyan University. Analyses of 500 
specimens have been completed and a report of the work is now 
being prepared. The investigation is thus more extensive than 
any previously undertaken.
