Henry MULL, colored, is in jail at Washington, charged with killing his wife, a white woman, at Midland. It is alleged that MULL beat her to death with a pick handle. No one witnessed the tragedy. A mob of negroes from the Canonsburg region went to Houston to release MULL, but officers there had been notified and probably a race war was averted by the appearance of several armed officers at the lockup when the mob arrived.
