85
year, and the following statistics illustrate the
measurable results:
Baits laid (in 300 manholes) 17,256
Baits missing 15,842
Percentage of baits missing 91.2
Other methods of destruction carried out on an
experimental scale have been as follows:—
Rats killed
Breakback traps 42
Dustbin traps 195
Cage traps 202
In the absence of scientific methods applied on
a large scale, it may be doubted whether our present
efforts very materially affect the rat population.
OFFENSIVE MATTER.
During the summer months, the inspectors keep
special observation to see that offensive matter is not
conveyed through the streets during hours prohibited
by the by-laws. Legal proceedings were not necessary
during the year.
OFFENSIVE TRADES.
During the year, one offensive trade, that of a
Fur-skin Dresser, was carried on at 74, Florida
Street. 17 inspections were made at these premises.
No sanitary notice was served. Poultry slaughtering,
also an offensive trade, is dealt with elsewhere in
this report.

23 formal samples of rag-flock were taken during
the year, and in 2 cases the amount of chlorine
present was found to be in excess of the limit fixed
by the Regulations.
