Mill Full of Flour Burns.Fire completely destroyed the flour mill of W. J. Paff at McKinney, entailing a loss of $20,000, of which $15,-000 was on the building and $5,000 on machinery and grain stored. There was no insurance, the policies having been allowed to lapse a few days before the flre. The fire broke out late at night, from an unknown cause. The building was packed to its capacity with flour, none of which was saved.
