of  children  (splenic  census),  periodical  visits  to  the  schools, 
collection  of  statistics  as  regards  malaria,  and  preparation  of  reports 
as  to  work  done  and  results.  This  sounds  extensive,  but  a  good  deal 
of  the  work  is  overlapping. 
(d)  Mosquito  gangs :  These  would  vary  in  size  according  to 
locality,  and  would  be  controlled  by  a  headman  of  intelligence,  of 
whom  there  is  no  lack  in  Jamaica.  It  is  important  that  they  should 
have  a  distinctive  badge,  and  that  their  authority  should  be  upheld  and 
respected. 
Their  duties  would  be  principally  — 
1.  Clearing  pools  and  swamps  of  weeds. 
2.  Deepening  shallow  pools  and  swamps  where  feasible. 
3.  Filling  up  depressions. 
4.  Oiling  collections  of  water. 
5.  Inspecting  yards. 
6.  Serving  summonses  for  contraventions. 
(r)  Quinine  Dispenser :  Duties  already  detailed. 
XI.  COST 
I  have  not  the  material  at  my  disposal  to  give  an  estimate  of  the 
cost  of  the  measures  which  I  have  recommended,  but  I  am  sure  that 
it  will  not  be  found  to  be  prohibitive,  and  it  has  this  great  recom¬ 
mendation,  that  as  malaria  diminishes,  though  some  of  them  must  be 
permanent,  others  will  become  unnecessary,  and  expenditure  will 
diminish.  If  we  are  to  judge  of  the  results  elsewhere,  a  systematic 
campaign  against  malaria  will  in  ikree  years  effect  such  a  large 
reduction  that  there  will  be  an  enormous  saving  to  the  Government  in 
hospital  treatment  alone. 
XII.  EDUCATION  IN  SANITATION  AND  HYGIENE 
Lastly,  there  is  a  matter  to  which  it  is  necessary  that  attention 
should  be  drawn,  and  that  is  Sanitary  Education.  Adults  should  be 
attacked  by  means  of  pamphlets  and  circulars  drawing  attention  to  the 
evils  of  Malaria  and  the  simple  methods  of  its  prevention,  and  the 
vast  influence  of  the  clergy  can  be  utilised  to  no  better  purpose  than 
by  preaching  at  all  seasons  the  gospel  of  cleanliness  and  sanitary 
surroundings.  1  make  a  strong  appeal  to  them  for  their  assistance.
