Miscellaneous  Impalements  Exhibited  at  Gloucester,  1909.  217 
bring  the  manure  down  to  the  feed  wheels.  This  appears  to 
be  an  improvement  on  other  machines  of  this  class. 
No.  2610. — Tank  of  Re-inforced  Concrete.  Price  for  10ft. 
diam.,  3Z.  per  ft.  of  depth. — Exhibited  by  William  Hopkins, 
Montpellier  Works,  Cheltenham.  A segment  of  such  tank  is 
exhibited,  with  the  wrought  iron  mould  plates  in  position.  In 
light  soil,  where  the  construction  of  storage  tanks  is  at  once 
both  necessary  and  difficult,  this  plan  is  certainly  advantageous, 
more  especially  as  the  makers  propose  to  hire  out  the  moulds  at 
a reasonable  price,  and  the  work  can  then  be  done  by  ordinary 
farm  labour. 
Stand  223. — Butter  Moulder. — R.  A.  Lister  & Co.,  Ltd., 
Dursley,  Glos. — For  dealing  with  butter  or  margarine  in  large 
quantities,  delivering  it  in  pieces  moulded  to  shape  and  of  a 
definite  weight.  A near  approximation  to  an  ordinary  semi- 
plastic brick-making  machine.  The  butter  is  placed  in  a 
container,  where  it  is  worked  by  a series  of  pug  blades,  and 
forced  through  a die  on  to  a table,  where  it  is  cut  into  lengths 
by  a wire  frame  worked  by  hand.  The  name,  &c.,  of  the 
dealer  is  impressed  on  the  under  side,  by  a suitably  engraved 
roller,  immediately  the  butter  leaves  the  die. 
Nos.  2954-2956. — Millstones,  Diamond  Brand  Composi- 
tion.— Exhibited  by  Wm.  Garner  & Sons,  72  Mark  Lane, 
London,  E.C.  The  well-known  French  burr  stone  has  become 
difficult  to  procure.  The  above  stones  are"  made  of  the  quarry 
chippings,  ground  up  and  mixed  with  a suitable  binding 
cement,  so  as  to  nearly  resemble  the  natural  stone,  than 
which  they  are  somewhat  lower  in  price  and  more  equable  in 
texture. 
Stand  245. — The  Agent-General  for  Queensland,  1 Victoria 
Street,  Westminster,  S.W.  Of  very  considerable  interest, 
exhibiting  samples  of  all  the  products  of  the  colony. 
Nos.  3228-3235. — Petrol  Engines. — Exhibited  by  R.  A. 
Lister  & Co.  Ltd.,  Dursley,  Glos.  These  engines  are 
interesting,  insomuch  as  the  carburetter,  instead  of  being  pro- 
vided with  the  almost  universal  “ float  feed,”  has  the  spirit 
pumped  up  by  a continuous  running  pump,  driven  by  the 
engine  into  a closed  chamber,  about  level  with  the  jet,  and 
from  whence  the  latter  takes  its  supply,  the  surplus  spirit 
returning  by  an  overflow  pipe  to  the  reservoir. 
Stand  315. — Charlock  and  Thistle  Cutter. — Exhibited  by 
W.  N.  Nicholson  & Sons,  Ltd.,  Trent  Iron  Works,  .Newark-on- 
Trent.  On  the  points  of  the  tines  of  an  ordinary  hay  tedder 
are  fixed  long  cutting  blades,  parallel  to  the  axle,  the  sharp 
edge  faced  to  rear.  As  the  tedder  revolves  these  blades  cut  off 
any  high-growing  stems  close  to  ground.  Very  simple,  and 
would  appear  not  likely  to  get  choked  or  out  of  order.
