Pl.  XL.    Metal  Tray  and  Label  Holder. 
This  sketch  presents  a  device  for  exhibiting  lump  coal,  or  coal  in  broken 
fragments,  or  other  friable  substances.  The  form  is  that  of  a  deep  tray  with 
two  sides  divergent,  cut  down  in  front  to  a  narrow  strip,  the  contents  giving 
support  to  the  label. 
The  tray  is  made  of  tinned  iron,  bound  at  the  edges  with  wire  and  enameled 
a  drab  color  outside  and  white  inside.
