The hot, dry sawdust was charged at the upper end and the charcoal was removed continuously from the lower end. The ingenious devices 2 for. introducing the sawdust without introducing air and for removing the charcoal without allowing the escape of gas were found to work very satisfactorily 011 this demonstration retort.

It is reported that these
