Another  novelty  with  the  Pump  Se})arator  i.s  the  arrange- 
ment of  the  gearing.  The  driving  gear,  a spur  wheel,  engages 
a worm  or  skew  gear  on  an  intermediate  shaft  placed  at  an 
angle  of  45"  to  the  driving  shaft  and  to  the  vertical  spindle. 
At  the  other  end  of  the  intermediate  shaft  a second  spur  wheel 
matches  into  a worm  formed  upon  a sleeve  sliding  freely  upon 
the  vertical  spindle.  When  the  machine  is  started  this  worm 
sleeve  is  lifted  automatically  until  its  upper  end,  which  is 
serrated,  engages  with  similar  serrations  u[)on  the  vertical 
spindle,  driving  it  thereby  ; but  the  moment  the  driving  handle 
is  checked  or  stopped  the  sleeve  again  falls,  the  teeth  disen- 
gage, and  the  vertical  spindle  and  bowl  continue  to  run  freely; 
all  the  geai’ing  comes  instantly  to  rest  with  the  handle.  It 
will  be  seen  that  the  drive  has  a bmdency  to  lift  the  bowl  and 
spindle,  taking  some  of  their  weight  off  the  footstep.  The 
vertical  worm  being  free  can  be  re[)laced  in  case  of  wear 
without  having  a new  spindle. 
This  machine  was  tested  in  the  Dairy  at  the  Showyard 
with  the  following  results  : —

The  workmanship  of  this  separator  is  of  a very  high 
standard,  and  the  ease  with  which  it  is  driven,  as  well  as  its 
large  capacity  for  small  size,  is  (piite  remarkable.  The  pump 
is  very  simple  and  most  easy  to  clean,  and  in  addition  to  all  the 
other  good  qualities  of  the  Pump  Separator  it  is  undoubtedly 
a convenience  not  to  have  to  lift  the  milk  by  hand  into  a 
receiver  placed  above  the  .separator,  which  generally  necessi- 
tates the  presence  of  a second  attendant. 
Article  4351. — Mr.  James  1^.  Ilatntaker,  2S  Boulevard 
Malesherbes,  Paris.  “ Milk  Drying  Machine,  manufactured 
by  Messrs.  James  Milne  & Son,  Ltd.,  Edinburgh.” — It  is  not 
often  that  the  farmer  comes  face  to  face  with  such  a startling 
innovation  as  was  presented  to  him  in  this  machine,  which  was 
shown  in  operation  almost  continually  during  the  week  of  the 
Show.  Many  were  the  gloomy  forebodings  heard  on  all  sides 
as  to  its  probable  effect  upon  the  trade  of  the  dairy  farmer. 
The  machine  consists  of  two  cast-iron  cylinders,  28  in.  in 
diameter  and  GO  in.  long,  truly  turned  and  polished,  having
