ing 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.

The actual amount of corn, wheat, apples, and other crops shown was the
normal yield of one-hundredth of an acre of standard fertile soil of
Illinois. The milk shown was the amount that should be produced from the
same amount of land when growing crops suitable for milk production, and
the butter and cheese shown were such as could be made from this milk.

A mounted steer, which when living weighed 750 pounds, represented the
amount of beef that should be produced from an acre of soil in one year.
The same land would produce 10 such sheep as shown, weighing in all
1,100 pounds, or 100 pigs like the roaster shown, or their equivalent,
with a total weight of 1,400 pounds.

Incidentally the work in soil improvement was shown by a number of
yields from soils naturally deficient in fertility, taken both before
and after treatment, and thus showing the benefit of intelligent methods
of soil restoration.

The articles contributed by the College of Engineering were arranged in
an alcove, partly inclosed by cases of books and for folding frames, on
which were placed photographs and diagrams mounted on large cards. A
larger case contained the more bulky specimens of the work of
