coils  ; the  valve  cannot  be  against  both  seats  at  the  same 
time.  The  su})ply  of  oil  to  the  gland  through  which  the 
piston  rod  works  is  provided  for  by  the  very  simple  ex- 
pedient of  an  ordinary  dis[)lacement  lubricator  instead  of  the 
usual  pump. 
Attention  must  also  be  drawn  to  the  valves  which  are  inter- 
changeal)le  and  of  such  construction  that  on  unscrewing  a nut 
the  other  parts  come  away  by  screwing  one  part  into  another  ; 
the  spindle,  for  instance,  forming  a handle  for  drawing  out  or 
grinding  in  the  valve.  Thus  a single  spanner  is  the  only  tool 
required.  Great  compactness  is  obtained  by  using  the  hollow 
cast-iron  base  to  contain  the  condenser  coils.  This  is  the  best 
small  cold  storage  and  ice-making  ])lant  which  has  yet  come 
under  the  writer's  notice. 
Article  702. — Messrs.  Ransomes,  Sims  Jefferies,  Ltd., 
The  Orwell  Works,  Ipswich.  “ Patent  42-in.  Motor  Lawn 
Mower,  for  use  on  large  estates.”  Price  1.50/.  Fitted  with 
reversing  gear,  10/.  extra. — The  catalogue  .statement  of  claim 
“for  use  on  large  estates”  is  vague  and  misleading,  and  might 
lead  to  disappointment.  An  examination  of  the  claim  made  in 
the  form  of  entry  shows  that  it  shoidd  have  read  “ for  use  on 
cricket  grounds  and  other  practically  level  pleasure  grounds.” 
For  such  ])urposes  the  machine  proved  itself  to  be  well  ada[)ted 
and  will  undoubtedly  fill  a great  want.  It  is  driven  by  a 
8imms  petrol  engine  of  6 H.P.,  fitted  with  magneto  ignition 
and  water  cooler.  It  is  also  fitted  with  reversing  motion,  and 
this  and  the  driving,  steering,  and  grass  box  clearing  motions 
are  all  brought  ready  to  the  hand  of  the  driver  who  rides 
u[)on  the  machine  OAer  the  small  back  steering  roller,  l^y 
reason  of  its  weight  the  machine  is  an  effective  roller  as  well 
as  mower.

This  is  one  of  the  latest  novelties  among  cream  separators 
(Fig.  5).  In  many  respects  it  is  built  on  entirely  new 
principles.  Hitherto,  the  best-known  systems  have  the  Alfa 
or  similar  interiors,  i.e.,  inclined  plates.  With  these  it
