Mr. Leisen. Yes. Our highest hourly capacity for any one period was at the rate of about 190,000,000 gallons per day of 24 hours.

Mr. Tawney. The hour consumption was at that rate?

Mr. Leisen. That was the peak load, yes; for one hour during the past year.

Mr. Tawney. Have you studied this problem in connection with the matter of sewage disposal at all, or do you deal entirely with the water end of it?

Mr. Leisen. I have no official connection with the sewage disposal proposition; but my interests are simply those of an engineer in the problem, and as a citizen.

Mr. Tawney. Have you had any cases of typhoid fever in the city of Detroit in the last year or two?

Mr. Leisen. Yes; there have been cases, not abnormal. The typhoid-fever death rate has been reasonably constant for the last few years and comparatively low.

Mr. Tawney. Have you gentlemen any questions to ask? If not, that is all, Mr. Leisen. Are there any other gentlemen here representing the city of Detroit who wish to be heard on this subject? I see that the mayor of the city has just come in, in time to witness the closing of these hearings. He may have something to say. If he has we shall be glad to hear from him.

Mr. Marx. I do not know really what you have done this morning.

Mr. Tawney. Well, gentlemen, it seems that this closes the hearing. In concluding the hearing I have been requested, on behalf of the commission, to extend to the mayor of the city of Detroit and the council of the city our sincere thanks for the courtesy which has been extended to us in giving us the use of this council chamber. I can assure the mayor and the council that the commission sincerely appreciates, not only the courtesy that has been extended to us, but also the hearty cooperation which we have received from the officials of the city since the beginning of the investigation, and we sincerely hope that when our final recommendations are made to the two Governments they will receive the approval and support of the city of Detroit and of the neighboring cities as well. Thanking you gentlemen for your appearance and courtesy, I will state that the hearings are now closed.
