146 MINERAL RESOURCES OF MISSOURI. 



of pure lead that is known to exist, it is impossible to estimate. Lead has 

 been found in 61 counties of Missouri, of which there are but 27 counties 

 that are being worked, viz : Camden, Christian, Cole, Dallas, Dent, Frank- 

 lin, Henry, Hickory, Iron, Jasper, Jefferson, Lawrence, McDonald, Madison, 

 Maries, Miller, Moniteau, Morgan, Newton, Perry, Eeynolds, St. Francois, Sa- 

 line, Shannon, Washington, Webster and Wright. The counties in which lead 

 mining is not developed, although it is know to exist in paying quantities, 

 are 14, viz : Barry, Barton, Bollinger, Cooper, Crawford, Douglas, Greene, 

 Howell, Laclede, Eipley, Ste. Genevieve, Texas, Warren and Wayne. There 

 are also strong traces of lead in 20 counties, viz : Benton, Boone, Carroll, 

 Clark, Clay, Dade, Oregon, Osage, Pettis, Phelps, Polk, Pulaski, Eay, Eip- 

 ley, St. Louis, Schuyler, Scott, Stoddard, Stone and Yernon, but it will ne- 

 cessitate more thorough explorations to tell if in these latter counties lead 

 can be procured in paying quantities. Copper has been found in 19 coun- 

 ties that give promise of yielding profitable results. In several localities it 

 lies at an average of about 15 feet below the surface, the deposits being sev- 

 eral feet thick and paying about 50 per cent, of pure copper. Zinc ore is 

 abundant, but until recently it had no commercial value, and thousands of 

 tons of the sulphuret of zino were thrown away as worthless by the lead 

 miners, who found it an impediment in lead mining. Tin ores have been 

 found in large quantities, and so rich in metal that considerable capital has 

 been spent in efforts to mine and reduce them, but as yet without pecuniary 

 success. Gold has been found in two or three counties, but has never been 

 profitably worked. Silver has been discovered in regular lodes in five 

 counties, and in small quantities in nearly all the lead mines of the State, 

 in combination with lead. Cobalt exists in considerable quantities at Mine 

 La Motte, and it has also been found in one other locality. Nickel is worked 

 at Mine La Motte — it is abundant and of good quality. Antimony has been 

 discovered in large quantities in Cedar, Ste. Genevieve and other counties. 

 Saltpetre has been found in a number of different localities, but as yet none 

 has been manufactured. Platinum has been reported as existing in Madi- 

 son county, but nothing has been found to substantiate the assertion. Mar- 

 ble in Missouri is found in numerous and extensive beds, of various shades 

 and qualities, and will become a very important item of the State resources. 

 Livitstone. — There is a great variety of limestone in all parts of Missouri. 

 Hydraulie Limes have been found and tested in numerous localities and 

 found to possess first-class properties. Sulphate of Baryta is very abundant 

 in this state. It is largely utilized as a pigment in connection with lead, 

 Kaoline, from which ironstone china is manufactured, has been found in 

 several localities, and worked in one or two. Clays. — Potters', brick and 

 fire-clays have been found and worked in numerous parts of the State, 

 Paints. — There are several beds of raineral paints in Missouri of the finest 

 qualities. Sandstones are abundant, of various shades and color, that make 

 them readily valuable for architectural purposes. Granite and Sienite of 

 numerous qualities occur in this State. The most abundant is the red, cross-
