64 administrative work.
number of complaints with reference to smells (sulphuretted hydrogen) arising from an ice
factory opened at the end of March. In the last case the smells were due to the incomplete
purification of wash-water from the scrubbers belonging to a "suction gas" plant. The
nuisance has been obviated by the use of tanks packed with oxide of iron through which the
wash-water is passed before being discharged into the sewer.
Drainage Work.—The drainage systems of 287 houses were re-constructed during the
year, as compared with 554 in 1909, and 605 in 1908. In addition the drains of 12 houses

tested for various reasons, and found to be sound. In 1909, 97 drains were found on first
test to be water-tight.

drains at 26 houses were tested during the year, 14 proving to be defective. In 5 other

source of the rats in 2 cases, and rats left under the houses after reconstruction of the drains,
in the remaining.
Deposit of Drainage Plans, etc.—Last year 303 sets of plans and notices were received, as
