GALLERIES OF THE SOUTH COURT. 
Cases 1 and 1A.— The Cork Oak {Quercus suber) and its 
utilization. 
Among the specimens exhibited is a very fine and costly de- 
cortication of a tree with three branches. This specimen is con- % 
sidered to be the best example of dextrous cork-peeling ever 
procured. 
Cases 2A, 2B, 2C, 2D, and the wall space accompanying 
same, are devoted to the indigenous trees of Illinois. 
Notable in this collection is a complete set of the oaks of Illi- 
nois, accompanied by water-color representations of the leaves 
and fruits. 
Cases 2E, 2F, 2G, and the accompanying wall space, are 
devoted to the cultivated trees of Illinois. 
Fine examples of Honey Locust, White Ash, and several 
species of Oak. 
Case 2H. — Grains of Illinois. 
RUSSIA. 
Case 3. — Russian Tobacco. The first tier in this case com- 
prises the original natural species (. Nicotiana rustica ), from which 
most of the finer cultivated forms have sprung. The balance of 
the specimens are of the variety known as Turkish leaf, from dif- 
ferent sections of the country. 
Case 3A.— Russian Flax. In this case may be found ex- 
cellent specimens of dressed and undressed flax, together with 
the plants from which this useful fiber is obtained.
