This was a Class B building. The walls were of brickwith wood floors s\i|)|iorte(l by steel framing. The only part of the building fire-proofed was the columns. These were coveredwith stone concrete, anchored with No. 10 gauge steel wire wrapped spirally around the column at IG centres. Thisbuilding was filled with a stock of paints, oils, etc., producing a hot, spectacular fire, and causing the total wreck of thestructure. Note the tenacity of the concrete cfihmin protection, which remains in jilace after the .severe fire test and the jarringsustained by the columns in falling over. The granite bases are badly spalled, this material being unsuited for carrying loadsin locations where it is exposed to fire. 256 The liollow tile blocks which were most generally used \aried considerably in efficiency.
