REPORTS OF GEOLOGISTS. CV11 



The lead ores assay as high as eighty-five per cent of metallic lead, zinc 

 ores fifty-six per cent of zinc, copper ores seventy-eight per cent of copper. 

 Bismuth, tin, antimony, molybdenum are found in small quantities. 



Analyses made in the laboratory of the lignites of Texas have been com- 

 pared by you with the German lignites which are used for making briquettes 

 and coke, and shown to be superior to them both as fuel and as steam gen- 

 erators. 



The fertilizers (Greensands) of Texas are not so good as those of New Jer- 

 sey, yet can be used with great profit on our poorer lands. In fact, there is 

 hardly a mineral of economic value that is not found in our State. 



As to the monetary value of the work done by the Chemists in the Labora- 

 tory during the year, at present I can only give approximate figures. Count- 

 ing each analysis as valued at $20, which is a very low figure, as most of the 

 ores will far exceed this estimate if regular prices were charged, it will amount 

 to more than $12,000. At the end of the year, if a careful estimate of the 

 work is made, I have not the slightest doubt but that it will exceed $25,000.
