As he spoke, Lennard saw what seemed to him like an illimitable sea of huge spumy billows and tumbling masses of foam, which seemed to roll and break over each other without sound.
"The World Peril of 1910"
George Griffith
Now from the lowest depths, As yellow sands they turn, the billows shine; Now blacker seem they than the Stygian waves; Now flatten'd, all with spumy froth is spread.
"The Metamorphoses of Publius Ovidus Naso in English blank verse Vols. I & II"
Ovid
It was not till then that they felt their terrific danger; in the swirl of those spumy and hissing waves it was all but impossible for them to make head against the current, and they felt it carry them nearer and nearer to the black, dripping mass, one blow of which would stun them, and one revolution of it mangle them with horrible mutilation.
