Mr. Perkins. The engineers could state this better; but it would be a mere bagatelle as compared with $3,000,000 for the sewage treatment necessary, and then the river water would not be desirable for drinking purposes.

Mr. Gardner. Could Prof. Phelps make a statement in regard to the cooperation we are seeking and the desirability of it, and also what the gist of the reference is. It should be fresh in our minds before we talk ourselves.

Mr. Powell. We have had it from Capt. Norton and the others. Ask the authorities of Buffalo city exactly what they want. Do they want a postponement of the hearing; and if so, how long?

Mr. Kreinheder. How long would it take your engineer to make this study?

Mr. Powell. Your engineers are working with them. They collaborated on this.

Capt. Norton. The work the city did was in furnishing the information and discussing the differences here. We had a good many talks over the local conditions and getting such ideas as they had. There was no work done by the department of public works on the report further than a discussion in this way.

Mr. Powell. And it takes a much shorter time to revise than it would to work out the scheme in the first instance.

Capt. Norton. I do not suppose you would care to have us work out another plan?

Mr. Tawney. I was going to suggest that it might not be necessary to have a further hearing, as I understand Capt. Norton and Mr. Hill. What they contemplate doing is employing sanitary experts or engineers to go over this matter and consider such modifications as were suggested by Capt. Norton this morning, and their conclusions could be submitted to us in the form of a report to us without any further hearing. As I understand it the city of Buffalo does not wish to have any more hearings, but they wish to submit some considerations based upon reports from sanitary engineers.

Capt. Norton. That would be my engineering idea, and in connection with that suggestion it would occur to me that the other cities might join in an examination of that kind, so that we could have their ideas.
