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 compared 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 generators.

The fertilizers (Greensands) of Texas are not so good as those of New Jersey, 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 Laboratory during the year, at present I can only give approximate figures. Counting 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.

Below is a table showing the amount and character of work done during the year:
