And what do you make of that ?' I pointed to a flat rock below tide-mark covered with a tangle of seaweed.

It was of a softer stone than the hard stuff in the hills and somebody had scraped off half the seaweed and a slice of the side.

'That wasn't done yesterday morning, for I had my bath here.' Wake got up and examined the place.

He nosed about in the crannies of the rocks lining the inlet, and got into the water again to explore better.

When he joined me he was smiling.
