I longed miserably for the places where white men were thronged together in dorps and cities.

As we gazed a curious sound struck our ears.

It seemed to begin far up in the north--a low roll like the combing of breakers on the sand.

Then it grew louder and travelled nearer--a roll, with sudden spasms of harsher sound in it; reminding me of the churning in one of the pot-holes of Kirkcaple cliffs.

Presently it grew softer again as the sound passed south, but new notes were always emerging.
