Report  on  Implements  at  York. 
dirty  water  were  taken,  with  a view  to  analysis ; but  on  several 
occasions  during  showery  weather  little  difference  was  per- 
ceptible, and  observation  fully  confirmed  the  experience  of 
Mr.  Copperthwaite,  derived  from  actual  measurement.  The 
Society  are  much  indebted  to  this  gentleman  for  thus  enabling 
the  Judges  to  arrive  at  conclusions  which  they  regret  were  not 
more  favourable  to  Mr.  Roberts’s  ingenious  apparatus.  The 
value  of  such  in  densely  crowded  and  dirty  towns  will  indeed 
be  great  whenever  he  is  able  to  reduce  the  proportion  of  waste 
water,  and  I am  glad  to  hear  that  the  Sanitary  Association 
has  awarded  him  a silver  medal. 
Messrs.  F.  and  J.  S.  Bust,  of  Winterton,  Lincolnshire,  ex- 
hibited a power  “ Ensilage  ” Cutter,  so  arranged  that  the  cut 
material  could  be  delivered  direct  into  the  silo.  The  fly-wheel, 
being  provided  with  a series  of  fans,  and  working  in  a close- 
fitting  cover,  to  which  air  is  admitted  below,  acts  as  a blower, 
and  throws  the  cut  grass  for  a considerable  distance — of  great 
value  in  filling  a silo.  The  fly-wheel  carries  5 knives,  which 
work  very  close  to  the  face  of  the  box.  The  feed-rollers  are 
specially  arranged  to  prevent  clogging,  and  apparently  this  is 
a highly  efficient  cutter,  but  the  question  arises,  for  what  crops 
it  will  be  required  ? Inasmuch  as  nearly  the  whole  of  our  storage 
material  is  grass,  which  packs  closely,  and  cuts  out  easily, 
why  go  to  the  expense  of  reducing  such  material  by  passing 
it  through  a chopper?  We  can  understand  that  where  coarse 
woody  material  is  used,  such  as  corn-stalks,  then  a powerful 
cutter  may  be  very  necessary. 
This  firm  also  exhibited  a Chaff  Elevator  and  a Salt 
Sprinkler.  The  former  consists  of  a long  chamber  in  com- 
munication with  a small  fan,  which  forces  the  chaff  out  of  the 
spout  with  great  violence,  and  is  said  to  convey  it  to  a distance 
of  15  feet,  a useful  appendage  to  their  power  chaff-cutter,  where 
the  store-room  is  at  an  elevation  from  the  ground.  The  salt- 
sprinkler  consists  of  a small  box,  fixed  at  the  head  of  the  chaff 
elevator,  with  a revolving  spindle  furnished  with  a number  of 
short  arms,  and  a false  bottom,  the  opening  of  which  can  be 
regulated  according  to  the  quantity  of  salt  which  is  to  be 
added.  The  salt  mixes  with  the  chaff  as  the  latter  falls  from 
the  elevator  into  the  sacks.  The  advantage  of  using  a certain 
proportion  of  salt  with  the  food  for  all  our  farm  stock  should 
be  more  generally  recognised.  Sheep-stock,  especially,  have 
been  preserved  in  health  during  recent  wet  seasons  by  this 
means,  and  this  simple  method  of  adding  the  salt  is  very 
practical  and  efficient.  The  cost  of  the  Salt  Sprinkler  is  4/.  10s. 
Mr.  Thomas  Constantine  Fawcett,  of  Burmantofts  Foundry, 
Leeds,  who  is  well  known  in  connection  with  brick-making 
machinery,  exhibited  a complete  novelty  in  a Safety  Valve  for
