ly, the carp, buffalo, the
coarser catfishes, and dogfish. The dogfish in the last few years has
become a very important factor in the food supply, having been
previously thrown away as worthless, but is now extensively used by a
class of people in the larger cities and sold alive under the name of
grass bass. In this aquarium has been carried, for a period of seven
months, perhaps the largest amount in weight ever carried in an aquarium
for that length of time with so small a percentage of loss.

In the smaller aquaria were shown the game fish of the State, a list of
which comprises the black bass, crappie, sunfishes, yellow perch, white
perch, warmouth bass, and the two varieties of striped bass.

These aquaria have attracted a great deal of attention, particularly
among those who were interested in the subject of fish propagation and
distribution, and gave people a better idea of what Illinois produced
than could have been obtained by any other method.

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 accord
