South American towns. It is a clean-water mosquito, although occasionally 
it may be found in dirty water, and hence it is found in the clean water 
receptacles to the almost complete exclusion of all other species. In Chapter 
III., devoted to the mosquito survey of Belize, I have shown that it is widely 
distributed in that town ; I have found it also at the other principal ports in 
the Colony, and at Livingston, Puerto Barrios and Puerto Cortes, always in 
the same place — the clean water receptacles in the yards. 
6. — Screening of Water Supply. 
In Chapter IV., on the water supply of Belize, I have discussed the 
methods which should be adopted to prevent water receptacles from becoming 
breeding grounds, and I am of opinion that Sections 39 to 47 Ordinance 29 of 
1894, should be brought into force, with certain additions agreed to by the 
Committee who met the Superintendent of Public Works and myself, to discuss 
the matter (Ch. IV.). At the same time I feel that it would be to the public 
advantage, and an example which would place the Colony in the forefront of 
Central American sanitation, if a separate Ordinance were made to include 
those clauses which would deal with the screening of cisterns and the abolition 
of odd receptacles, wells, and other foci which might act as breeding places. 
Such an Ordinance to be called the “ Screening Ordinance,” or “ The Ordinance 
for the Prevention of the Spread of Disease by the Destruction of Mosquitoes.” 
The Ordinance might be framed upon that approved for New Orleans, 
August 2nd, 1905, and which runs as follows : —
