I was swimming along leisurely, interested only in my thoughts and the water immediately around me, when something a bit ahead attracted my attention.

I was half-way between Rita's Isle and the shore at the time. The object in front kept bobbing,—bobbing. At first, I took it to be part of a semi-submerged log, but as I drew nearer I was quite surprised to find that it was an early morning swimmer like myself. Nearer still, and I discovered that the swimmer was a woman whose hair was bound securely by a multi-coloured, heavy, silk muffler, such as certain types of London Johnnies affected for a time.

Whoever the swimmer was, she had already gone at least half a mile, for that was the distance to the nearest point of land and there was no boat of any kind in her tracks.

Half a mile!—and another half-mile to go! Quite a swim for a lady!

Afraid lest it should prove more than enough for a member of what I had always been taught to recognise as the more delicately constituted of the sexes, I drew closer to the swimmer.

When only a few yards behind, she turned round with a startled exclamation.

It was Mary Grant.

A chill ran along my spine. I became unreasonable immediately. What right had she to run risks of this nature? Was there not plenty of water for her to swim in near the shore where she would be within easy hail of the land should she become exhausted?

Almost angrily, I narrowed the space between us.

She had recognised me at her first glimpse.
