From Malaita the Ariel steered west of north to Ongtong Java and to Tasman--great atolls that sweltered under the Line not quite awash in the vast waste of the West South Pacific.

In such way had vanished all the worlds and harbours and roadsteads and atoll lagoons where the Ariel had had lifted her laid anchor and gone on across and over the erasing sea-rim.

The atoll of Hikueru lay low on the water, a circle of pounded coral sand a hundred yards wide, twenty miles in circumference, and from three to five feet above high-water mark.

Half an hour later, Huru-Huru, watching from the seaward side of the atoll, saw the two boats hoisted in and the Aorai pointing her nose out to sea.

Miles in length, carrying tens of thousands of tons in weight, its impact shook the frail atoll like an earthquake.

This was the highest spot of land in miles, and already, in many places on either hand, the great seas were making a clean breach of the slender ring of the atoll and surging into the lagoon.

Even as Captain Lynch spoke, a great watery mass smote the atoll.

I live on an atoll, a low island, it is a strip of land surrounding a lagoon, and its beauty is the beauty of the sea and sky and the varied colour of the lagoon and the grace of the cocoa-nut trees; but the place where Strickland lived had the beauty of the Garden of Eden.

Near Keeling Atoll, in the Indian Ocean, I observed many little masses of confervae a few inches square, consisting of long cylindrical threads of excessive thinness, so as to be barely visible to the naked eye, mingled with other rather larger bodies, finely conical at both ends.
