to the Ministry of Agriculture, Fisheries and Food for the year ended

The inspection and treatment of sewers was undertaken in collaboration
with the Borough Surveyor. Ten per cent. of the total

treatment was carried out in these, and other manholes known to be

were baited and 181 showed evidence of rodent infestation.
The Department continued to deal with rodent treatment and
disinfestation work in Council-owned property within the Borough.
