chestnuts and the beeches belong here. The oaks (Quercus) 

 are represented by many species. One of these is the 

 pinnatifid-leaved oak, from Japan, with its odd leaves cut 

 into long linear lobes; it is said to be a form of the toothed 

 oak of Japan. Near by is the rock chestnut oak, of eastern 

 North America; its wood is strong and durable, especially 

 when in contact with the soil, and is therefore of great 

 value for railroad ties and fence posts, and its bark is 

 largely used for tanning. The mossy-cup, or bur oak, also 

 of eastern North America, may be found here; this was 

 discovered by the botanist Michaux in 1795, and is a 

 valuable timber tree, its wood largely used for boat-build- 

 ing, for the manufacture of carriages and agricultural im- 

 plements, for the interior finish of houses, and, on account 

 of its durability in contact with the soil, for railroad ties. 

 The red oak and the swamp white oak are natives of 

 eastern North America; the latter is also a good timber 

 tree, its wood being used for cabinet work and in various 

 kinds of construction. The Japanese silkworm oak forms 

 a part of this collection; its leaves are much like those of 

 the chestnut, and might easily be mistaken for them; it is 

 often planted in Japan in the silk districts, as its leaves are 

 available as food for the silkworms, whence its name; the 

 Japanese make charcoal from its wood, and from the bark 

 they extract a black dye. The post, or iron oak is a native 

 of the eastern United States. Here may be seen also the 

 sessile-flowered English oak, a native of Europe and western 

 Asia. The large-toothed oak, of Japan, a valued timber 

 tree there, is represented near by; as is also the gland- 

 bearing oak, another Japanese species. The shingle, or 

 laurel oak, of the central parts of the United States, is not 

 of much commercial value, as its wood checks badly in 

 drying; it is sometimes used in making clapboards and 

 shingles. Schneck's red oak comes from the south central 

 parts of the United States. The Turkey oak, of south- 

 eastern Europe and western Asia, is valued in that region 

 on account of its bark which is used in tanning leather.
