PROGRESS IN AGRICULTURAL EDUCATION. 283 



BELGIUM. 



It was the purpose of the organizers of the Brussels Exposition of 

 1910 to make it more than a demonstration of the industrial and 

 commercial activity of the nations participating. With a view to 

 giving it a permanent intellectual value, a series of congresses and 

 conferences was provided for as one of the main groups of the expo- 

 sition, which were held from April to October. There were some 69 

 of these congresses and a number of conferences, which had to do 

 with a wide variety of subjects. 



Among the congresses of special interest to students of agriculture 

 may be mentioned the international congresses of horticulture, bot- 

 any, tropical agronomy, entomology, popular education, agricultural 

 associations and rural demography, apiculture, and alimentary 

 hygiene, and the rational nutrition of man, as well as conferences 

 which had to do with municipal sanitation and domestic architecture. 



The Brussels congress of alimentary hygiene and the rational nutri- 

 tion of man was the second international congress to be held, and 

 like the fii'st is due to the initiative of the French Societe Scientifique 

 d'Hygiene Alimentaire. The foreign countries invited to participate 

 in this congress were asked to form organization committees, and Dr. 

 H. W. Wiley, chief of the Bureau of Chemistry, acted as chairman of 

 the American committee. Dr. C. F. Langworthy, who was chairman 

 of the Am^ican subcommittee of section 1, biological physics and 

 energetics, also supervised the collection of American papers on nutri- 

 tion and other branches of home economics, and was in attendance 

 at the congress. 



In view of the interest and activity in human nutrition in this 

 country, as evidenced by the work and the teachings of the federal 

 department, the experiment stations, and the agricultural colleges, 

 it seemed desirable that the American work along these lines should 

 be adequately represented at the Brussels congress, and an effort 

 was accordingly made to collect papers and other illustrative material. 



The response from the teachers, investigators, and others con- 

 cerned was quite general, although the time was short. Some 30 

 papers were received from the land-grant institutions, other col- 

 leges, normal schools, etc., in the United States, which give home 

 economics courses. 



These papers treated of such subjects as descriptive accounts of 

 courses in home economics at the University of Wisconsin, Univer- 

 sity of Minnesota, Teachers College, and University of Illinois; the 

 respiration calorimeter of this office and the work undertaken with 

 it; the respiration calorimeter used in cooperative experiments at 

 the Institute of Animal Nutrition, Pennsylvania State College; the 

 American Home Economics Association and its work* a brief account
