does  not  attack  his  stock  ;  and,  moreover,  it  does  not,  so  far  one  could 
gather,  occur  in  sufficiently  large  numbers  to  cause  any  appreciable 
annoyance  to  man  or  his  domesticated  animals.  Further  information 
regarding  this  tick  is  given  in  other  parts  of  this  Report  (pp.  445,

Apparatus 
The  terms  ‘  sprays  ’  and  ‘  washes  '  are  practically  synonymous,  as 
the  agents  used  in  both  cases  may  be  identical  in  composition.  But 
tick-infested  cattle  must  be  treated  according  to  the  existing 
conditions  or  size  of  the  herd.  Small  owners  need  go  to  no 
expense  in  the  purchase  of  apparatus,  as  washes  can  be  applied 
with  a  suitable  brush,  a  piece  of  cloth,  or  a  bundle  of  tow ; 
but  for  larger  herds  the  pen-keeper  will  require  either  a 
spraying  apparatus  or  a  dipping  tank.  There  are  numerous  forms 
of  spraying  machinery  on  the  market,  which  for  the  most  part  are 
rather  costly.  For  experimental  purposes  we  used  a  Stot’s  Syringe 
fitted  with  one  of  their  fine  nozzles  and  a  Cooper’s  ‘  Bucket  .Spray 
Pump,’  kindly  furnished  by  the  inventors.  The  syringe  proved  by 
far  the  more  convenient  apparatus ;  it  was,  moreover,  extremely 
economical,  there  being  practically  no  waste  of  material.  By  its  use, 
also,  the  spraying  was  carried  out  expeditiously,  and  the  movements 
of  the  animal  could  be  much  more  easily  followed  than  with  a 
heavier  piece  of  apparatus.  The  Stot’s  syringe  or  hand  sprayer  costs 
I  os.  6d.  (f.o.b.),  the  Cooper’s  spray  pump  28s.  6d.  (f.o.b.).  The  best 
form  of  brush  for  liquid  washes  is  tne  kind  used  for  grooming  horses, 
known  technically  as  a  '  body-brush.’  A  native-made  brush,  in  general 
use  in  the  Island,  is  prepared  from  the  fruit  stalk  of  the  cocoanut 
palm  ;  it  forms  an  excellent  apparatus  for  applying  thick  tar  and  oil 
preparations.  Out 'is  quite  unsuitable  for  the  more  mobile  washes. 
The  use  of  diffing  tanks.  This  is  undoubtedly  the  most 
efficaceous  means  of  treating  tick-infested  stock,  as  has  been 
abundantly  proved  in  other  parts  of  the  world.  Unfortunately, 
dipping  is  out  of  the  question  in  some  localities  owing  to  the  scarcity 
of  water  at  the  time  when  stock  most  require  dipping.  But  there 
are  certain  parts  of  the  Island  where  public  dipping  tanks  could  be 
erected,  and  there  are  certain  estates  on  which  it  would  repay  the 
owners  to  erect  such  a  structure  for  their  own  use  exclusively.  This
