gray south to Mason ?li Record of the rim valley, we saw the next lower thin bedded as shale=Upper Cambrian and finally the hard Silic. and argillaceous. further SE Sandstone. Then came red granite and finally schist. In places near to N.1/4 Mason saw hard Sandstone and finally that the town is built on hardening sandstone. The State map is all wrong in this matter. From Mason to Austin it is 125 miles. Left Mason 2:30 P.M. Ten miles S of Mason we are again in basal Silic.=Upper C. Mostly gneiss and schist. At 13 mile S. more Silic., above Silic at 16 and SE, between schist and greens. The schist and green continues to 25 miles S of Mason where the Comanchian rests directly on these ancient complexes. Left to Fredericksburg in due time. Thirteen miles east of Freed. in the Pedernales river bottom saw the Ellensburgn explored. It continues explored far to the NE of Houston City. See State Map. Comanchian overlies it. Left to the hotel at Austin at 7:30 P.M. Great crowd here; tomorrow the State Legislature meets.
