Five Lumber Fires in Three Weeks. What the police declare to be the fifth incendiary lumber yard fire to occur in Philadelphia within three weeks, on November 5 wiped out the plant of the Improved Moulding Manufacturing company in the northwestern section of the city. Shortlv before the fire was discovered a man was seen jumping the fence which surrounded the plant. The loss is estimated at $40,000. All the fires have occurred in the northern and northwestern sections of the city. The Lumbermen’s Exchange of Philadelphia offered a reward of $1,000 for the arrest and conviction of a firebug after the night fire at Williams’s lumberyard on November 2, when $300,000 worth of lumber was burned.
