Metropolis.
To the Main Drainage Committee.

circular letters to the engineers and surveyors of the various vestries

main sewers.

Hall on Friday, 25th February, at which upwards of 40 of the
gentlemen invited were present. A list of those who signed the
attendance book, together with the names of the districts represented
by them, is appended hereto.

frequent intervals.
2. That in connection with any interceptor hereafter fixed on
a main house drain it is advisable to carry up a ventilating pipe
from the sewer side of the interceptor, up the front, side, or
back of the house, to the satisfaction of the local sanitary
