   • 1951, "Nation's Owners Can Expect 400,000 Fires Every Year," Milwaukee Journal, 11 March, p. 12:

     If you own or are building a frame house, make sure that it is adequately fire stopped. Fire stops are blocks of wood, brick or gypsum board placed between the walls and partitions at each floor level and at the eaves level. These blocks retard the upward passage of fire between the studs in hollow walls.
