The details of this arrangement are suggested bySketches 5 and 6. By reference to these figures, it will be seenthat two columns In a), having their support in an extensionupon the exhaust pipe, are provided as guides for the draft pines:The draft pipe Ii slides freely on these columns, being appliedthereto h\ some form of filling which will admit of easy adjustment.
