Mr. Hatton. Yes; but just what that report contains I am not familiar enough with it to say.
Mr. Powell. The flow is always out?
Mr. Hatton. Yes.
Mr. Magrath. I have an idea that the water works inward sometimes?
Mr. Hatton. Well, it comes down, as I say, on the west side, passes round Chicago, and comes up on the east side, and passes out in the straits; at least, that is my opinion.
Mr. Magrath. I may be wrong, but I had an idea that the current moved inward sometimes, and sometimes outward.
Mr. Hatton. Well, possibly so. This is the general tendency of it, but I think it does sometimes pass out and in, according to the direction of the winds.
Mr. Powell. The Chicago Drainage Canal is not equal, I suppose, to the inflows from the surrounding country. It does not balance it?
Mr. Hatton. Well, I think not. It is claimed here very recently that the waters taken from the Chicago Drainage Canal have lowered the waters in the connecting streams some 5 or 6 inches. How true that is I am not prepared to say. Now, before deciding upon the method of sewage disposal for Milwaukee we built rather an elaborate experimental station, in which we tried to put all those modern methods of sewage disposal now prevalent in this country and abroad, and I think we had 23 different processes going on there at one time—one of the largest experimental stations carried on in this country for sewage disposal purposes.
Mr. Mignault. When was it established?
