In March 1907 Regulations were made under Section 8 of 

 Ordinance 188 to deal with yellow fever by screening patients, 

 fumigation, etc., and by prohibiting the keeping of stagnant 

 water, unless properly protected. It runs as follows : 



{a) No water shall be stored (except in small quantities 

 for drinking purposes) unless efficiently protected against 

 mosquitos by the following method : 



All tanks, barrels, etc., for storing water shall have 

 all openings except the draw-off opening covered with 

 wire-gauze (18 mesh to the inch), or with a piece of cheese 

 cloth or fine mosquito netting, and all fountains, pools, 

 ponds, antiformicas or excavations made for any purpose 

 whatever, in public or private property, which may 

 contain water, shall be kept stocked with mosquito- 

 destroying fish, or shall be kept covered with a film of 

 petroleum oil. 



{b) The occupier or owner of any premises shall keep such 

 premises free of stagnant water, liable to breed mosquitos,
