I tempted my sisters to go and bathe where the shore shelved rapidly and the ebb washed back strongly.

They went, and to my chagrin were delighted with the place, and learned to swim better than I could.
There was a man who went out every morning to bathe from a boat.

I was always at the pier-head watching him, but he went into the water and scrambled out of it again over the stern of the boat with ruthless regularity, and quite mistook my interest in him for admiration, which was the very last sentiment I harboured.
Once I made sure my chance had come.

It was a warm day, and the shore was crowded.

Most of the people had finished bathing, and were spread about the sands drying their back hair and reading their papers.
