Can anybody help with the bold text?
And then the foghorns began their warnings. The low, menacing roar from Point Bonito. The wailing siren on Alcatraz. Sausalito's throaty bass. The deep-toned bell on Angel Island. She knew them all, but they seemed to come from new directions. A second ... a moment... an hour... later... a foreign but unmistakable note. Ships — two of them... Blast and counterblast... She could barely see his white rigid face through the mist as he thrust his head this way and that trying to locate those sounds.
...Another abrupt swerve... crash... shouts... her own voice shrieking as she saw his head almost severed — the very fog turned red-She could hear herself screaming yet. It seemed to her that she had been screaming since the beginning of time.
The Foghorn, Gerthrude Atherton, 1933
