The plunger, how-ever, on being left to itself, descends by its own gravity,pressing upon the water below, which, unable to ascendthrough the annular space on account of the closing of thevalve, is forced through the small central opening in thelatter, through the pipe B, and finally out at the spout ina fine jet sixteen or eighteen inches high.
