Shade-tree insects. Like that representing forest insects, the exhibit of shade-tree pests was very largely biologic. It occupied three horizontal trays and a nearly vertical one of the exhibit case, and was devoted to species which are destructive largely on account of their depredations upon shade trees.
Adirondack insects. This was a small collection occupying one of the nearly perpendicular trays, and comprised over one hundred species. This portion of the exhibit represented the more characteristic forms occurring in the Adirondacks.
Natural group of forest insects. This group occupied the central glass box and contained thirty-one species of insects or representations of their work upon wax models of their food plants, namely, white birch, red oak, elm and maple. Eleven species of beetles, fifteen of butterflies and moths, two of the bee family and three of the bug family were to be seen upon the plants or on the ground at their base. This group gave an excellent idea of the appearance of insects when amid their natural surroundings.
COLORED PLATES
A series of quarto and octavo colored plates illustrating the work and various stages of some of the more important depredators upon forest and shade trees, was exhibited in two double-faced frames attached to the top of this case. The more important insects included in this group were the following: Sugar maple borer, elm snout beetles, twig girdler or twig pruner, white marked tussock moth, gypsy moth, brown tail moth, bag worm, forest tent caterpillar, elm leaf beetle, oyster scale, scurfy bark louse, San Jose scale, elm bark louse, cottony maple scale. One plate was devoted to characteristic insects affecting oak, and another to those depredating upon hard pine.
SPECIMENS OF NATIVE WOODS
The forest product of the State was represented by a collection of specimens of all the native woods of New York, built into panel work, showing both sides. Each species was represented by two specimens and each of the four surfaces was finished in a different manner. One surface was highly polished, one oiled, one planed and one rough. Ninety-one species of native and nine species of introduced woods were exhibited in this manner. Displaying the several species in four different ways enabled the discriminating observer to study and compare the various woods profitably. The manner of labeling was greatly appreciated. Some students copied all the labels, each spending many hours on this task.
