By Dr. Jordan.
394.-You say it would burst from over-pressure of water not from over-pressure of gas?
A. Yes. You may say we have not experienced a "perfect" sewer here yet. Hitherto all the gullies and house drains have been so defective that there have been hundreds of outlets for the gas to escape by and relieve the pressure.
By the Chairman.
395.-Have you found that during one of the heavy rainstorms, there is such an amount of sand and mud carried down as to burst the drain by choking it?
A.-There is a great deal carried down which would reduce the sectional area.
396. But not to such an extent as to choke the sewer?
A.-Not that I know of.
By Dr. Yarr.
397. You consider ventilators at every fifty yards necessary?
A.-I think so, every fifty or hundred yards.
By Dr. Manson.
398.-Would not the smell be intolerable then?
A. You notice them in London, Croydon and other towns every hundred yards or so, and there is no smell from them.
By the Chairman.
399.-Are you aware of any
defective drains in the Western district?
A.-No, I don't know of any. I consider the drains, such as they are, made of granite, very good drains. They are on an antiquated section, the same as was adopted when the Colony was first laid out.
400.-But to your knowledge they carry out their work very well?
A. Yes.
401.-Even though made of granite?
A. Yes, for granite sewers.
By Dr. Yarr.
402.-You mean the principal is wrong?
A. Yes.
By Dr. Manson.
403.-Who is responsible for this plan of ventilation that is being adopted now?
A.-I don't know.
404.-Is it Mr. CHADWICK?
A.-I don't know. Sir ROBERT RAWLINSON'S plans for laying out sewerage drains and water supply as issued by the Local Government Board are looked upon
