Mr. Kyle. Yes.
Mr. Gardner. And from navigation also?
Mr. Kyle. Yes, sir; also from navigation.
Mr. Powell. You are in favor of that as applying to the whole community, but you think that it would be of no avail for any particular community to attempt purification because of the communities above?
Mr. Kyle. Yes, sir; because the boats would still contaminate the water.
Mr. Powell. Have you ever brought to the notice of the steamboat association the pollution of the waters of the river through the boats?
Mr. Kyle. Only by ordering them away from our docks. We have a dock at the pumping station where the boats sometimes land, and we have refused to allow them to land; but that applies more to our old intake pipe than to the present one.
Mr. Powell. But the fact remains that their presence there has the effect of polluting the water?
Mr. Kyle. We simply ordered them away as a precaution.
Mr. Powell. Was it a mere precautionary measure or was it because they were a source of pollution?
