‘The value of the output [11894] was $62,350, which is quite 'an increase 
over the product of a few years ago. The output comes from quarries in

“There appears to have heen quite a falling off in the limestone industry 
in Texas. The total value of the output was only $41,526. OVIost of this 
went for building and road making. The productive counties are Coryell, 
El Paso, Bell, Williamson, Travis, Hood, Grayson, Hamilton, Lampasas, and
