days  :  and  in  our  experience  every  five  to  eight  Aveeks  during  the 
winter  months  is  sufficient  to  keep  the  cattle  practically  free  of  ticks. 
2.  All  sprayings  or  washings  should  take  place  in  the  early 
morning ;  and  the  cattle  should  be  allowed  to  dry  in  the  shade  before 
turning  out  to  graze. 
3.  If  cattle  have  to  be  driven  for  any  distance  they  should  be 
allowed  to  cool  before  spraying.  Driving  both  before  and  after 
should  be  quiet. 
4.  Cattle  of  all  ages  and  also  cows  in  calf  may  be  sprayed.  Cows 
in  milk  should  have  the  lower  portions  of  their  udders  sponged  before' 
milking  on  the  first  day  of  the  spraying. 
5.  The  spray  should  be  so  finely  distributed  that  practically  none 
of  the  liquid  drips  off  the  animals  treated.  To  avoid  danger  the 
operation  should  be  conducted  on  a  site  devoid  of  grass. 
6.  All  waste  products  and  washings  from  the  apparatus  used 
should,  be  thrown  into  the  drains,  or,  safer  still,  into  a  hole  in  the 
ground  and  covered  with  a  layer  of  soil. 
7.  All  these  instructions  are  applicable  both  for  dipping  as  well 
as  for  spraying.  But  in-calf  animals  should  not  be  dipfed  a  month 
or  so  before  calving. 
We  have  every  confidence  in  recommending  this  preparation, 
which,  although  containing  arsenic  is  perfectly  safe.  The  cattle 
treated  by  us  did  not  suffer  in  the  least ;  moreover,  Cooper’s  dip  and 
other  arsenical  preparations  have  been  in  use  for  several  years  in 
Africa,  Australia  and  South  America,  and  although  thousands  of 
cattle  have  been  put  to  the  test  in  all  of  these  countries  no  loss  has 
been  occasioned  when  the  regulations  for  its  use  have  been  strictly 
carried  out 
In  the  conditions  obtaining  in  Jamaica  we  do  not  consider  that 
dipping  is  a  practicable  method  ;  it  is  too  costly,  consumes  too 
much  wash,  and  is  not  without  risk  to  stock.  We  advocate  spraying 
with  a  wash,  as  above,  possessed  of  such  wetting  power  that  a  very 
fine  spray  will  sei  \'e  to  wet  and  destroy  all  the  ticks  at  one  operation.
