The Argo mill, which caught fire at 3 o'clock yesterday afternoon, burned to the ground, causing a loss of nearly $50,000. Insurance to the amount of $32,000 is carried in six milling companies, but this amount includes the grist mill and 9,000-bushel elevator, valued at about $4,500, which were saved. The fire broke out in the roller room and was discovered by head Miller Sherk and his assistant, H. F. Wolf, who had been in the room only a few moments before, when everything was all right. An alarm was turned in at once, but the flames spread with almost incomprehensible rapidity and by the time the fire department arrived the entire interior of the building was a raging furnace.
