The exhibits of the common schools and the five State normal schools were installed under the direction of the State superintendent of public instruction. The material of the exhibits was furnished, except that from the normal schools, by the school districts, without expense to the commission, and in substantial conformity to the following suggestions, sent to the schools about November 1, 1903: _Classification of schools._--Group 1. Elementary education.--Class 1. Country schools. Class 2. Semigraded schools. Class 3. Graded schools. Group 2. Secondary education.--Class 4. High schools. Class 5. Normal schools. Under this classification it is desired to exhibit: (1) Legislation, organization, general statistics; (2) buildings, photographs, plans, models; (3) administrative methods; (4) results obtained by methods of instruction. The educational exhibit of the university of Illinois occupied a space 30 by 45 feet, or an area of 1,290 square feet, open upon an aisle on its long dimension. Against the back and the two side walls were glass-inclosed cases 7 feet high, and above these were many enlarged photographs in frames, showing the main buildings, views of the campus, etc., together with numerous pictures from the department of art and design, also a set of finely colored plates of the food and game fish of Illinois. Other cases occupied a part of the central area of the space, with room for seats and a writing table. The exhibits were classified according to general subjects illustrative of the equipment and work of the colleges of the university from which they came. An attendant was on hand to supply published documents and information to visitors. The exhibit of the college of science contained diagrams and photographs and a set of bound volumes of the contributions to science published by the members of the college faculty, but was otherwise almost wholly illustrative of the work of only one of its eight departments, that of chemistry, and in this it was confined to the results of two line of investigation, which have for some years been closely associated with the work of the department; first, a study of the chemical composition and heating value of the coals of the State, and, second, a sanitary survey of Illinois waters. The importance of the first is emphasized by the fact that Illinois ranks second among American States in tonnage output, with a valuation in the aggregate of $35,000,000 annually. The agricultural portion of the university exhibit was designed to show the comparative produce of Illinois soils expressed in terms of both crops and animal products. The yields shown were of corn, wheat, oats, beans, potatoes, apples, tomatoes, milk, butter, cheese, port, mutton, and beef.
