Trials  of  Fruit  Tree  Spraying  Machines.  195 
No.  382,  one  of  French  make  shown  by  Messrs.  Besnard, 
was  worked  by  air  pressure,  having  an  air  pump  fitted  outside 
the  lead-coated  steel  container.  This  machine  did  good  wdrk. 
No.  1468,  Messrs.  Mayfarth  & Co.’s  “ Syphonia  Knapsack  ” 
was  a 2|-gallon  lead-coated  steel  container  worked  by  air 
pressure,  the  liquid  being  pumped  into  the  container. 
Of  the  nozzles  used  in  the  trials,  we  found  the  large 
“ Seneca  ” pattern  the  best  for  lime  and  salt  spraying,  and 
for  the  Bordeaux  Mixture,  Messrs.  Weeks  & Son’s  “ Multi- 
spray ” nozzle,  the  “ Mistry  ” pattern,  and  the  “ W.E.K.”  did 
the  best  work.  As  a general  purpose  nozzle,  Messrs.  Drake  & 
Fletcher’s  adjustable  “ Mistifier  ” was  very  satisfactory. 
A word  should  be  said  with  regard  to  the  spray  mixtures 
used  in  the  trials.  While  the  lime  and  salt  wash  and  the 
Bordeaux  Mixture  were  sufficiently  satisfactory  for  the 
purpose  we  had  in  view,  viz.,  to  test  the  machines,  yet  owing 
to  the  very  poor  quality  of  the  lime  and  of  the  bluestone 
provided,  they  would  have  been  quite  unsuitable  for  use  in  a 
commercial  fruit  plantation.  We  mention  this  only  in  order 
to  remind  growers,  many  of  whom  took  advantage  of  the 
Society’s  courtesy  to  view  the  trials,  of  the  importance  of 
taking  the  greatest  care  in  the  purchase  of  the  materials  and 
in  the  mixing  of  the  spray  fluids. 
In  conclusion,  we  were  much  indebted  to  Mr.  Martin 
Chart  for  the  excellent  preparations  he  had  made  in  his 
gardens  for  conducting  these  trials  ; and  we  also  desire  to 
express  our  thanks  to  the  Stewards  of  Implements,  Mr.  R.  M. 
Greaves  and  Mr.  Claude  M.  S.  Pilkington,  for  their  assistance, 
and  to  the  Consulting  Engineer,  Mr.  F.  S.  Courtney,  for  the 
help  he  gave  us  in  carrying  out  our  duties.
