Four Japanese doctors are at present employed on this duty having been en- gaged for a period of six months.
The number of rat-catchers in the em-
ploy of the Board at the end of last year was twenty-two. The Board has now one hundred and thirty-two rat-catchers and rat-poisoners.
This is specially arranged for, rat-poi- soners being sent to these districts daily.
No marked migration of rats has been observed, except during the house to house cleansing when they left the disin- fected houses.
This has been prosecuted vigorously.
Rat poison and rat traps have been freely used; carbolic acid is poured into rat runs. The question of the treat- ment of ships was referred to the Cham- ber of Commerce who were not in favour of taking active steps in this direction.
No Danysz virus has been prepared owing to the loss at sea of all Dr. HUSTER'S apparatus, duplicates of which have not yet arrived in the Colony.
A special Ordinance has been passed to secure this, and it is administered by the Police.
