following five cases occurred on board.

Now all these ports had Yellow fever in those years, and the run is under 
five days. 
During the present year (1905) the following cases, all members of the 
crew, were taken from ships entering the Mississippi.

There is, therefore, no question that in infected places infected persons 
can be taken on board, and that unless there is strict and careful quarantine 
such cases may infect infectible places on arrival or infect the Stegomyia if 
it is on board, which in its turn may infect dock labourers, Custom House 
officials, or pass to shore and spread infection, just as would happen if infected 
mosquitoes were taken on board. 
Sea Trade of Belize with United States , Mexico and Central American 
Republics : — In order to determine the amount of intercourse by ships between 
Belize and the neighbouring States, with the object of throwing light upon 
the recent epidemic, assuming that the chances of infection were proportional 
to the number of sailings, I asked Mr. Walcott, the Collector of Customs, 
to furnish me with tables of the number, tonnage and crews of steam and 
sailing vessels entered at British Honduras in the years 1902, 1903, 1904 
and 1905 to September of this year, he has kindly done so, together with a 
memorandum on the sea trade, which I reproduce. 
Summarising the tables it will be seen that the total number of steam- 
ships is less than the total number of sailing ships, and that, whilst the 
greatest number of steamships comes from the United States, followed by 
Guatemala and Honduras, the sailing ships from Mexico, Honduras and 
Guatemala are much more numerous, viz. : —

Very significant is the fact 
that 
the total number of 
sailing 
ships from 
Mexico were largely in excess of other neighbouring States from January to 
September, 1905. Given the presence of Yellow fever in or around the 
port from whence the ships came, then the chances of infection from Mexico 
are greater than from other States. In a preceding chapter I have shown 
that Yellow fever is endemic in Mexico, and that there are numerous foci.
