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. The kinds of timber that grow in this State from which a five-inch board can be sawed and which were represented as described, are as follows: Cucumber Tree Tulip Tree Basswood Linden Holly Striped Maple Hard Maple Silver Maple Red Maple Box Elder Staghorn Sumach Kentucky Coffee Tree Honey Locust Red or Canada Plum Wild Plum Green Ash Sassafras American Elm Rock Elm Slippery Elm Wild Red Cherry Wild Black Cherry Wild Crab Apple Mountain Ash Cockspur Thorn Black Haw Scarlet Fruited Thorn Shad Bush Witch Hazel Sweet Gum Flowering Dogwood Pepperidge Persimmon Black Ash White Ash Red Ash Scarlet Oak Black Oak Pin Oak Jack Oak Hackberry Red Mulberry Sycamore Butternut Black Walnut Bitternut Shagbark Hickory Mockernut Hickory Pignut Hickory King Nut Hickory Small Fruited Hickory White Oak Post Oak Burr Oak Chestnut Oak Chinquapin Oak Yellow Oak Swamp White Oak Red Oak White Pine Red Pine Pitch Pine Jersey Pine Yellow Pine Jack Pine Tamarack White Poplar Crack Willow Weeping Willow Lalanthus Chestnut Beech Ironwood Blue Beech Black Birch Yellow Birch White Birch Red Birch Canoe Birch Yellow Willow Black Willow Peach Willow Aspen Large Toothed Poplar Swamp Cottonwood Balm of Gilead Cottonwood Red Cedar White Cedar Arbor Vitae Black Spruce Red Spruce White Spruce Hemlock Balsam Lombardy Poplar Wild Apple Yellow Locust Horse Chestnut Blue Willow These specimens of wood were built into panel work in seven frames of the following seven species of wood, respectively: Maple Cherry Chestnut Rock Elm White Oak Black Ash Black Birch LABELING OF SPECIMENS
