_Potguns_ (vol. vi., p. 612.).--DR. RIMBAULT, in reply to J. R. R.,
explains _potguns_ by "small guns." {191} They are, in fact, short
cylinders set perpendicularly in a frame, "flat-candlestick"-wise, four or
six in a row; and were fired by a train of powder running from touch-hole
to touch-hole, as a part of the entertainment (a _feu-de-joie_, I suppose)
at the public grounds at Norwich some twenty years ago, as I remember.
