brought up by a conjoint Committee of the Sewers and Sanitary
Committees. These recommendations are set out in full on pages
2148-9 of the 1898 Minutes, and practically approve of Combined
Drainage for new buildings, under certain conditions, e.g., (a) all
drains to be outside; (b) no more than six houses to be allowed
to drain into one combined system, if only one interceptor from
the main sewer is provided; (c) where more than six houses are
approved, the main drain to be placed at the rear of the houses,
and treated separately as to ventilation, etc., and into this back
line of drainage each house to be drained separately, and
separately intercepted and ventilated.
(g) Sewer Ventilation.
A series of recommendations (conjointly suggested by the Medical
Officer and the Surveyor) were adopted by the Vestry on the
13th April, 1899. The recommendations were to be carried out
subject to the previous approval of the Vestry, and will be found
to be fully set out on pages 700-1 of the 1899 Minutes, and to have
reference to the Free Ventilation of Sewers by means of sufficient
surface road ventilation in wide roads, supplemented by shafts as
may be necessary, together with a careful, regular, and systematic
flushing of sewers, and the clearing away of all deposits, or the relaying
of such sewers where found to be defective or worn out,
together with the substitution of glazed pipes for brick barrel.
The closing of all open grids in narrow and crowded streets,
courts, alleys, and passages is insisted upon, with the substitution
therefor of ventilating shafts of sufficient calibre (not less
than six inches), one shaft being taken, if practical, from the
highest point of the sewer, which, if a stunted or dead end, should
be tacked on to a neighbouring sewer to allow of free circulation
of air.

In addition to the special matters mentioned, there is the
Daily Routine Departmental Work, as follows: —
