"Everything's a matter of custom," said I to myself; and in another minute I was racing gaily down to the water, hand in hand with Sally, as if we had been little girls with sand pails and shovels.

I expected to feel as if I had plunged into a million-gallon bath of iced water, when I got out among the creamy breakers; but judging from the sensation, Americans have had their part of the Atlantic beautifully warmed from underneath, with some patent heating apparatus. It would be just like them!

The sandy beach is so level, you can patter out ever so far, until you finally have to bob up and down for the rolling waves, as if they were Royalties--and so they are, for the Kingdom of Mer. I can swim a little, and Potter took me beyond the breakers. It was great fun, under that arch of turquoise sky, with the sun dancing on the clear green water, as if the millionaires of Newport had been sprinkling gold pieces. But the best of all was the floating platform, about a hundred yards from the beach, where we sat and let the emeralds and pearls that the Princesses of Mer threw, spray over us.

At home, when you are at the sea, your governess or some other person who thinks enjoyment ought to be measured off by rule, sits on the shore looking at her watch; and when you have been in exactly twenty minutes she tells you to come out directly, or you will catch a chill. I've always wondered what it would do to you if you stopped in for twenty-one minutes, though I never had the chance to try; but in America all that is quite different, as different as the very way they say "seaside," with their accent on the first instead of the last syllable.

Nobody thinks about watches. You just bathe and bathe as long as you feel like it. When you are tired of it you come out; then you bake yourself in the sand for a little while if you like, and run back to begin over again. It is heavenly. No other adjective half expresses it.

When we did really make up our minds to stop out for good, and had dressed ourselves, feeling like goddesses just born of the foam (or gods, as the case might be), we all met--our party, the Pitchleys and my cousin,--to arrange about what Mohunsleigh would do.

It seemed that Mrs. Pitchley had invited him to lunch, and as she had been so kind about the bathhouse, he explained to Potter, he thought that he couldn't very well refuse. About stopping on, he would decide later; but he consented to drive with us in the afternoon, in a motor car of Potter's that holds six. By that time, he would have had time to send a wire to a friend of his in New York, and to make up his mind what he had better do about going back.

When we got home, we found Mrs. Ess Kay much better, and up. She was inclined at first to be cross with Sally and Potter for taking me to the beach; but when she heard about Mohunsleigh, she forgot to be vexed, and seemed almost excited about him, I can't think why.

She asked lots of questions, very quickly, one after the other, brightening up when Potter told how he had invited Mohunsleigh to come to The Moorings, but looking quite strained and wild at the news about his lunching with the Pitchleys.

"You oughtn't to have let him go, Potter," she said.
