It was in the myth that they circumnavigated Malaita twice, and forayed as far as Ugi and San Cristobal across the wide seas.
Women they had inevitably stolen after successful combats, and, in the end, being burdened with women and progeny, Somo had descended upon the mainland shore, driven the bushmen back, and established the salt-water fortress of Somo.

Built it was, on its sea-front, like any island fortress, with walled coral-rock to oppose the sea and chance marauders from the sea, and with launching ways through the walls for the long canoes.

To the rear, where it encroached on the jungle, it was like any scattered bush village.

But Somo, the wide-seeing father of the new tribe, had established his boundaries far up in the bush on the shoulders of the lesser mountains, and on each shoulder had planted a village.

Only the greatly daring that fled to him had Somo permitted to join the new tribe.
