_Vegetable Productions._--_Trees, &c._ Almost every species of timber and shrub common to the Atlantic states is found in some part of the Western Valley. The cotton wood and sycamore are found along all the rivers below the 41° of N. latitude. The cypress begins near the mouth of the Ohio and spreads through the alluvion portions of the Lower Valley. The magnolia, with its large, beautiful flower, grows in Louisiana, and the long leaf pine flourishes in the uplands of the same region. The sugar maple abounds in the northern and middle portions. The chestnut is found in the eastern portion of the Valley as far as Indiana, but not a tree is known to exist in a natural state west of the Wabash river. Yellow or pitch pine, grows in several counties of Missouri, especially on the Gasconade, from whence large quantities of lumber are brought to St. Louis. White pine from the Alleghany river is annually sent to all the towns on the Ohio, and further down. Considerable quantities of white pine grow on the upper Mississippi, along the western shore of Michigan, about Green bay, and along the shores of lake Superior. The yellow poplar, (Liriodendron tulipifera) is a majestic tree, valuable for light boards, and may be found in some parts of most of the western states. The beech tree is frequently found in company. The live oak, so valuable in ship building, is found south of the 31°, and along the Louisiana coast. The orange, fig, olive, pine apple, &c. find a genial climate about New Orleans. High in the north we have the birch, hemlock, fir, and other trees peculiar to a cold region. Amongst our fruit bearing trees we may enumerate the walnut, hickory or shag bark, persimmon, pecan, mulberry, crab apple, pawpaw, wild plum, and wild cherry. The vine grows everywhere. Of the various species of oak, elm, ash, linden, hackberry, &c. it is unnecessary to speak. Where forests abound, the trees are tall and majestic. In the prairie country, the timber is usually found on the streams, or in detached groves.
