QUOTE : I was just about to call for assistance when, some twenty feet away from me, the sea seemed to part with a gentle swish and gurgle, a gleaming back appeared, gave a deep, satisfied sigh, and sank below the surface again. I had hardly time to recognise it as a porpoise before I found I was right in the midst of them. They rose all around me, sighing luxuriously, their black backs shining as they humped in the moonlight... Heaving and sighing heavily, they played across the bay, and I swam with them, watching fascinated as they rose to the surface, crumpling the water, breathed deeply, and then dived beneath the surface again, leaving only an expanding hoop of foam to mark the spot. Presently, as if obeying a signal, they turned and headed out of the bay towards the distant coast of Albania, and I trod water and watched them go, swimming up the white chain of moonlight, backs agleam as they rose and plunged with heavy ecstasy in the water as warm as fresh milk. Behind them they left a trail of great bubbles that rocked and shone briefly like miniature moons before vanishing under the ripples.
