Mr. Powell. You think a fair estimate of the total population would be 50,000?

Dr. Goodale. Yes, sir. Of course, it is all guesswork. I have no means of knowing.

Mr. Powell. You never took a poll or made a census?

Dr. Goodale. No; I have been looking after sewers and sick people.

Mr. Powell. What do you do with the excreta or raw sewage?

Dr. Goodale. Do you mean our garbage?

Mr. Powell. No; the excreta from the inhabitants.

Dr. Goodale. From the water-closets or toilets?

Mr. Powell. Yes.

Dr. Goodale. We dump it into the river. It goes down through the main sewer.
