I daresay _that_ was only river water, if we had known.

But we did not know, so it was all right.
What the eye does not see, the stomach does not get upset over.
We tried river water once, later on in the season, but it was not a success.

We were coming down stream, and had pulled up to have tea in a backwater near Windsor.

Our jar was empty, and it was a case of going without our tea or taking water from the river.

Harris was for chancing it.
