Thus probably the first coke in any quantity was burned from coal piled in heaps on level ground, with suitable flues through the piles built of lumps of coal, refuse coke and slabs of wood for igniting the coal and regulating the supply of air, the whole banked with earth. I have seen a fair quality of coke produced in this way not more than six years ago. Meeting of Structural Section, September 2," l'.iOli. t W. G. Wilkins Co., Westiiighpuse Building, Pittsburgh, Pa.
