One of great free-wheeling oil booms of America before proration was enforced. Population in Mexia increased from 4,000 to 50,000 within days after oil discovery in 1920 at Rogers No. 1 Well, located 1.6 miles west of this marker, just off FM Road 1633 Earlier (in 1912), Blake Smith and other Mexia men had brought in a gas field. Believing oil also could be found here, they interested a veteran operator flamboyant wildcatter A. E. Humphreys-- who struck oil at 3,105 feet. By May 1912 gushers were flowing. Humphreys had 2,000 men; did a $4,000,000 business. His fortune later was estimated at $37,000,000. The boom was on. Other companies were formed. A second renowned wildcatter, J. K. Hughes, shared the leadership in developing the field to capacity. Millionaires, merchants, celebrities, operators and workers swarmed to Mexia for a share in the "Black Gold." Many undesirables came also, and one day were ousted by the thousands by Texas Rangers. In 1920-1921 first boom year, $5,000,000 went into construction; tanks for over 30 million barrels of oil were built; but even so storage area was inadequate for output. A park and clubhouse developed near this site by Col. Humphreys-- mementos of boom-- are still in use. 1967
