delayed by opposition and other circumstances but I should think very soon we must hear of its confirmation by the Queen, when it can be proclaimed.
By Dr. Young.
741.-Mr. GILLIES complains in his evidence that two stones have been taken off the top of that sewer which runs up the hill, east of his house, Rose Villas, and that it has been left open. Do you know any reason for that?
A.-Possibly there may have been some work going on there. I was not aware of the circumstance.
742.-It has been open now for two months.
A. In the street is it? [Dr. YOUNG--No; it is about 20 feet off.. Is this the drain to which you allude? [Refers to plan.] There is no sewer gas from that drain. Is is well trapped below at this point.
743. He complains of a very bad smell from it.
A.-Perhaps things may have been thrown in, but it is trapped down there. 744. He says he can almost see it, that he sees a vapour.
down.
A.-A hole like that would be a great temptation for a coolie to throw night soil
By Dr. Cantlie.
745.-If you covered over the ground in Hongkong for a distance of one hundred yards, say, up the hill, would you not at the top perceive an odour, without any drainage of anything?
A.-I don't know. I should think not. If anything I should expect to perceive an odour at the lower end.
746.-Why?
A.-Because the percolation of sewage would be down hill.
747.--Would that carry the sewer gas down the hill?
A.--That is a hypothesis which I have never considered-covering over large surfaces and imprisoning whatever was in the ground.
748.-When a stream is running down a sewer it carries the air down with it, does,
it not?
A.-It does.
749. Of what use will a ventilation shaft be, then?
A.--Because in sewers which are on steep gradients sewer gas being lighter than atmospheric air travels upwards.
750. So there must be two currents?
A. The upward current is the normal one. The gas current that runs with storm waters is an adventitious current.
751.-There are no flaps at the outlets of the sewers in Hongkong?
A. A great many have them.
752. Do you know if the one at Richmond Terrace has a flap?
