of yellow fever occur in the so called fumigated houses, and that the method is 
brought into disrepute I do not think that the authorities in Belize any more 
than in other places had realised the necessity of issuing stringent directions for 
the destruction of the Yellow Fever Mosquito, because in an official circular 
which the Health Board issued this summer it is stated : — “ Inside of houses 
care should be taken to destroy mosquitoes as much as possible, especially if 
there are any cases of fever in the neighbourhood. This may be done by 
burning either insect powder or tobacco leaf freely in the room after closing the 
doors and windows ; afterwards sweeping the ceilings, walls and floors, and 
destroying the sweepings (which will contain dead and stunned mosquitoes) by 
fire.” This paragraph is of very little use to the householder, and it certainly 
will not bring about the effective destruction of mosquitoes ; on the contrary, a 
sense of false security may ensue. Those who have worked with culicides 
know that the quantities of materials to be used must be specified, the sealing 
must be complete, and the exposure a definite time ; that a little practice is 
necessary, and that tobacco leaves are not used because it is exceedingly difficult 
to fire them, that special apparatus is necessary, and that the smell penetrates 
everything. I therefore recommend that the District Board be given powers 
to execute fumigation in the houses surrounding the infected house, and that 
the distance be not specified, but that this be left to the discretion of the Board 
acting' on the advice of the medical officer. 
Whilst I am of opinion that the fumigation of an infected house and the 
houses surrounding should be carried out by the health authorities, I think 
that the inhabitants of the town should be encouraged to fumigate their houses 
in a systematic and scientific manner, and not to rely on carrying a little insect 
powder alight on a shovel through the rooms, which is as effective as the old 
native plan, still adopted in some places, of lighting bonfires in the streets. For 
that end I think that it would be of advantage if the District Board would 
undertake for a nominal fee the fumigation of houses when they were applied to. 
If the camphor-carbolic compound is used, householders would be distinct 
gainers, as moths and objectionable vermin would be killed, and there would be 
no damage to furniture or clothes, by either smell, smoke, smuts or corrosion. 
ERADICATION OF THE STEGOMYIA FASCIATA. 
Eradication of the Stegomyia fasciata underlies the action of any attempt 
to get rid of Yellow fever. 
The problem is one which, although at first sight may appear difficult, is 
in reality a comparatively simple one, practicable and not costly. 
5. — Mosquito Survey. 
The immense mass of evidence connected with the distribution and life 
history of the Stegomyia fasciata shows that it is essentially a town or 
domestic mosquito. That it breeds either in the yard or in the house, that 
it does not breed in the swamps or to any great extent in the gutters, but 
that its usual breeding place is the innumerable collection of cisterns of all 
patterns, barrels and cans which are present in abundance in Central and
