Interior of the oven house of the Tapper Lake Chemical Co., Tupper Lake, 

 N. Y., showing the outside doors of the oven?. In the immediate foreground 

 is a turn-table from which the loaded wood cars are sent into the oven for 

 distillation. The residual charcoal is withdrawn from the same door and sent 

 into the first cooling ovens, which are on the right of the picture. The white 

 spot in the left foreground indicates the opening through which the charcoal 

 is fed into the furnaces beneath. For fuel, charcoal, wood gas and tar are used. 

 On the right is a wood car containing charcoal which is shovelled directly into 

 the fiunaces. Twenty-five foot ovens which contain two cars at a charge, 

 are used in this plant. There are seven ovens arranged in a row.
