A.-I cannot say.
The Chairman. Do the contractors make any difference if you ask for Tung Kung lime?
A. We dont ask for it. We ask that the lime shall be good and fresh.
Q. How do you know they use Tung Kung lime ?
A.-I know, because the contractors tell me.
Mr. Shelton Hooper.-Do you think it is possible to make a floor that is impervious to damp on that specification ?
A. Yes, I think so. I had an experience the other day at Kowloon in which we had laid with the same proportions, four inches thick. A spring had formed at the bottom through the heavy rains in September, and the concrete.was prised off by the water under- neath without coming through the substance of the concrete. It was shifted out of its position.
The Chairman. The concrete was not actually broken?
A. It was cracked across the middle. It was on a slope. It was about 20 feet by 5 feet that was forced off.
Q-The water had not made its way through the concrete ?
Mr. Shelton Hooper.-Had it not disintegrated the concrete?
A.-No.
Q. Is that Tung Kung lime hydraulic ?
A. Yes.
Q. Do you think that sufficient quantities could be got if it was specified in general use in the Colony ?
A. Yes, I think so.
Q-You think the bulk of lime used in the Colony now comes from there?
A. Yes, from what the contractors tell me.
The Chairman. Do you know what form it comes down in ?
A. It comes down in slack lime or powder.
Mr. Fung Wa Chun.-What sort of lime is that?
A. It is rock lime,-burnt limestone.
The Chairman.--Where is it worked,-on the banks of the East River ?
A. Somewhere up there. I dont know exactly.
Q. You dont know if it is brought down in the form of stone?
A.-No.
