clay aud maintaining on an average 7 or 8 per cent, of water. As 

 the soil becomes heavier in texture, and the amount of water increases, 

 other grades and types of tobacco are produced. 



" The export tobacco lands of Kentucky and Tennessee contain 

 about 22 or 2o per cent, of clay, and, as a characteristic feature, they 

 contain from 40 to 60 per cent, of silt. These soils contain on an 

 average about 15 per cent, of water. 



" The characteristic soil of the limestone area of Kentucky, 

 adapted to the White Burley tobacco, may be said to maintain on an 

 average about 20 per cent, of water. 



" Records have not been kept of the manufacturing tobacco soils 

 of Virginia, but from investigations which have been made on 

 adjacent lands, it is probable that the mean water content of these 

 soils, having as much as 40 per cent, of clay, will not be far from 

 20 to 22 per cent, of moisture." 



The Mechanical Analysis of a Few Typical American Subsoils. 



For comparison with the figures of the Edi soils, the returns are 

 given below of the average results of the mechanical analysis of a 

 large number of typical American subsoils. The very great ditference 

 in the relative clay percentage of the various soils adapted to each 

 type of tobacco, will indicate the very important part the physical 

 properties of the soil play in the production of the varying charactei'- 

 istics of the product.
