principal stream fliie timbered region extends westward to the State line; but in both 

 The northern and middle portions of ibe length of the county, considerable jiortiona of 

 its territory form parts of the Grand Prairie, which stretches, with few breaks, north- 

 ward to the Illinois Elver and westward nearly to the Mississippi.— (Firsi Re-port, 18b9, 

 p. 139.) 



Vigo Cottnty contains the usual variety of trees found in this latitude. Many of 

 the large black walnut and poplar trees have been converted into lumber, and vast 

 tracts of timber-lands are annually cleared for cultivation, but a noble forest yet re- 

 mains on portions of the uplands. — {Fimt Report, p. 114.) 



Washington County: 



Our most valuable timber is the poplar, of which about 80 per cent, has been used. 

 Next in value is black walnut, used for lurniture, of which about 85 per cent, has been 

 disposed of. Of the oaks, about 70 per cent, has been used ; and next, the hickory, of 

 which half remains. Of the white and gray ash, 80 per cent, has been used, as has 

 been nearly all the wild cherry. Of the sugar-maple, four-fifths has been cut off, for 

 lumber and cord-wood. — iLexoU J. Reijman, Salem, Washington County, Indiana.) 



White County: 



Sufficient for past and present wants has been obtained in the oak-openings and 

 along the streams. East of Monticello, I am informed, timber is abundant, and of 

 excellent quality.— (TAird and Fourth Reports, 1871-72, p. 302.) 



ILLINOIS. 



According to a list prepared some years since by Dr. George Vasey 

 (now botanist in the Uepartuaent of Agriculture), the number of species^ 

 of native forest trees growing throughout this State is 61 ; the number 

 peculiar to the northern part of the State is C, and the number peculiar 

 to the southern part is 14, making the total number of native species 81.^ 

 To this number there have since been added as peculiar to Southern 

 Illinois.
