"You—"

"For Heaven's sake, don't try to talk. Your one chance of remaining on the surface is to keep your lungs well filled. The fault," I said generously, "was mine. But when you have heard my explanation, I am sure you will forgive me. There, I told you so."

He reappeared some few feet to the left. I swam up and resumed:

"When you left us so abruptly after our little dinner party, you put me in a very awkward position. I was desperately in love with your daughter, and as long as you were in the frame of mind in which you left, I could not hope to find an opportunity of telling her so. You see what a fix I was in, don't you? I thought for hours and hours, to try and find some means of bringing about a reconciliation. You wouldn't believe how hard I thought. At last, seeing you fishing one morning when I was on the Cob, it struck me all of a sudden that the very best way would be to arrange a little boating accident. I was confident that I could rescue you all right."

"You young blackguard!"

He managed to slip past me, and made for the shore again.

"Strike out—but hear me," I said, swimming by his side. "Look at the thing from the standpoint of a philosopher. The fact that the rescue was arranged oughtn't really to influence you in the least. You didn't know it at the time, therefore relatively it was not, and you were genuinely saved from a watery grave."

I felt that I was becoming a shade too metaphysical, but I could not help it. What I wanted to point out was that I had certainly pulled him out of the water, and that the fact that I had caused him to be pushed in had nothing to do with the case. Either a man is a gallant rescuer or he is not a gallant rescuer. There is no middle course. I had saved his life, for he would have drowned if he had been left to himself, and was consequently entitled to his gratitude. And that was all that there was to be said about it.

These things I endeavored to make plain to him as we swam along. But whether it was that the salt water he had swallowed dulled his intelligence or that my power of stating a case neatly was to seek, the fact remains that he reached the beach an unconvinced man.

We faced one another, dripping.
