"  This  plant  is  a  narcotic  poison,  and  is  employed  in  some  fam- 
ilies for  destroying  the  house-fly.  The  bulbs  are  triturated  and 
mixed  with  molasses  or  honey,  and  the  preparation  is  spread  upon 
plates  and  placed  in  parts  of  the  house  most  infested.  The  flies  are 
soon  attracted,  and  the  poison  takes  effect  while  they  are  sipping  it. 
They  are  perceived  to  stand  unsteadily,  totter,  and  fall  supine.  The 
flies,  unless  swept  into  a  fire  or  otherwise  destroyed,  revive  in  the 
course  of  twenty-four  hours."  (Stephen  Elliott,  A  Sketch  of  the 
Botany  of  South  Carolina  and  Georgia,  Vol.  I,  p.  421,  Charleston,
