370 CONTBIBUTIONS TO ECONOMIC GEOLOGY, 1902. [bull. 213. 
Iii the extension of the marbles southwest of Knoxville line quarry 
sites are to be found 10 or 12 miles from Knoxville. In that vicinity 
the strata dip at small angles and cover a great surface. Conditions 
of drainage are also excellent there. In most of the other areas of 
marble the beds are more folded and dip at greater angles, so that 
prolonged quarrying will necessitate a great deal of stripping. Also, 
in districts far from the Tennessee River, the marble is likely to be in 
low ground, so that quarries would be near the drainage level. At 
present the great bulk of marble quarried comes from the vicinity of 
Knoxville. It is here well situated with respect to transportation over 
different railroads, besides being of the best quality. Good marble 
exists in immense quantities, however, in the other regions, and will 
become available as more favorable places are exhausted, as new means 
of transportation are found, or as the fashion in color changes.
