CONCLUSIONS 
1.  That  the  tick  responsible  for  the  transmission  of  Texas-fever 
IS  the  so-called  Texas-fever  tick  {Mar  gar  opus  annulatus  var. 
australis),  thoug-h  experimental  proof  is  needed  to  confirm  this  in  the 
Island  of  Jamaica 
2.  That  ticks  are  most  abundant  during  the  dry  season. 
3.  That  ticks  are  dispersed  from  place  to  place  chiefly  by  the 
host  to  which  they  are  peculiar. 
4.  That  rain  or  temporary  flooding  with  water  does  not  destroy 
ticks  or  their  eggs. 
5.  That  a  relatively  large  number  of  young  ticks  will  hatch  and 
possibly  survive  for  longer  periods  in  dirty  pastures  than  in  pastures 
which  are  free  from  weeds  and  scrub. 
6.  That  ticks  cannot  survive  indefinitely  and  reproduce  their 
species  without  access  to  a  host. 
7.  That  all  natural  enemies  of  ticks  should  be  encouraged  in 
every  possible  way,  and  that  fowls  should  be  kept  in  all  cattle  pens. 
8.  That  in  all  cases  where  it  is  practicable  the  burning  of  pastures 
should  not  be  carried  out  until  the  eighth  week  after  the  removal  of 
all  stock. 
9.  That  tick-infested  animals  should  be  thoroughly  sprayed  or 
dipped  regularly  at  intervals  of  five  to  eight  weeks,  or  at  less  intervals 
if  found  necessary.  Local  applications  being  of  little  use  in  the 
destruction  of  cattle  ticks,  though  useful  in  destroying  those  species 
which  infest  the  natural  cavities  of  the  horse  and  mule. 
10.  That'  the  effort  to  destroy  the  ticks  must  be  a  united  one  ; 
no  half  measures  will  serve  ;  all  must  participate  in  the  work. 
11.  That  the  evidence  of  those  pen-keepers  who  have  constantly 
waged  war  against  this  pest  is  that  ticks,  on  their  respective  estates, 
are  not  nearly  as  troublesome  as  formerly.  The  writer  very  willingly 
bears  testimony  in  support  of  this  statement. 
12.  That  the  Island  Government  remove  tiie  duty  from  all 
materials  used  in  spraying  and  dipping  cattle.
