There were also jars with samples showing the amounts of water, butter fat, casein, albumen, and other ingredients entering into the composition of a 30-pound tub of butter. Tables showing the value of the great dairy industry of Illinois, the production of butter and cheese in the Elgin district, the butter and cheese market of Chicago, and large photographs portraying typical Illinois dairy cows and Illinois creameries and the condensing plants occupied prominent positions among the exhibits. Several bulletins from the University of Illinois agricultural experiment station, showing the importance of clean milk and pure butter and other information of value to dairymen, were distributed from the superintendent's desk. The cheese exhibited consisted of samples made by students at the University of Illinois, and a large collection installed by M. Uhlmann & Co., of Chicago, occupied a space in the cheese case directly opposite the butter exhibit. The refrigerator which contained these exhibits had a glass front formed of three thicknesses of plate glass, with air spaces between. The temperature inside the case was kept close to the freezing point by an ice-making machine in constant operation. The Illinois commission set apart $15,000 to make a duplication as far as possible of premiums won by the breeders of live stock exhibited in the Louisiana Purchase Exposition, less than $1,000 of which was reserved to provide for the necessary expenses incident to printing, allotting, and distributing the said prize fund. The live stock from the State of Illinois won one-twentieth of the entire premiums offered by the Louisiana Purchase Exposition. Five thousand square feet of space was secured in the Palace of Horticulture at the exposition for the exhibit and installation and fixtures placed thereon prior to the opening of the exposition, May 1, 1904, upon which date the exhibit was put in place and maintained with apples from storage of 1903 crop until the crop of 1904 began to mature about June 1. From this latter date fruits of all kinds were supplied as they matured during the period of the exposition. Among the most popular varieties of apples exhibited were: For early apples--Yellow Transparent, Red June, Benoni, Wealthy, Duchess, Maiden Blush. For fall or early winter--Grimes Golden and Jonathan. Winter varieties--Wine Sap, Willow Twig, Rome Beauty, Ben Davis. Peaches--Reeves, Elberta, Diamond. Pears--Bartlett, Tyson, Sechel, Duchess. _Mines and metallurgy exhibit._--The mines and metallurgy exhibit covered a space 25 by 75 feet facing on two of the main aisles near the southeast entrance to the Mines and Metallurgy Building. The installation was uniform with that of the other exhibits of the State. The object of the exhibit was to show particularly the mineral and to some extent the mineral industries.
