plain, witli many lakes and morasses. The soil is of inexhaustible 

 fertility, and when reclaimed from the dense fjrests and . wild vegeta- 

 tion, will be the great center of agricultural wealth. 



All the leading geological formations, from the inetamorphic rocks 

 to the Tertiary, are well developed. The soils are nowhere more 

 varied, and the climate presents almost every phase from a tropica^ 

 summer to a frigid winter. For the study of geology and mineralogy 

 no State in the Union is more attractive. 



More than one half of the State is yet covered with the unreclaimed 

 forest trees, among which are the white ash, blue ash, red ash, water 

 ash, beech, birch, red cedar (in the counties of Marshall and Bedford, 

 solid cedar logs have been cut that would square twenty-four inches 

 for a distance of thirty feet), chestnut, wild cherry, cotton wood, 

 cypress, dog wood, white elm, slippery elm, wahoo, balsam fir, black 

 fir, black gum, sweet gum, shell-bark hickory, thick shell-bark hickory, 

 common hickory, pignut hickory, small-nut hickory, linn, black locust, 

 honey locust, sugar maple, swamp maple, wliite maple, red mulberry, 

 white oak, red oak, post oak, chestnut oak, black oak, scarlet oak, 

 black jack oak, swamp white oak, overcup oak, yellow oak, chinquapin 

 laurel oak, Spanish oak, willow oak, bear oak, yellow pine, white pine, 

 blue poplar, white poplar, yellow poplar, sassafras (a section of a sassa- 

 fras tree exhibited at the Industrial Exhibition, in Nashville, measured 

 five feet in diameter exclusive of the bark, which was one and a half 

 inches thick), sycamore, tupello, white walnut, and black walnut. 

 On the Cumberland table-land, in the eastern part of Morgan county, 

 walnut trees grow six feet in diameter, and rise to the height of more 

 than one hundred feet. One of the reasons that induced the city of 

 Cincinnati to invest $10,000,000 in the Southern Railroad was to get 

 access to this timber. [?] It is a curious fact, however, that a great 

 deal of walnut timber is shipped from Ohio to the Eastern States, and 

 even to Europe, and that the Tennessee timber will, sooner or later, be 

 shipped direct to the Atlantic coast. 



This work of the Bureau of Agriculture of Tennessee is much more 

 valuable than the books generally published by State Boards of Agri- 

 culture, and is creditable alike to the industry and ability of its authors.
