Chapter Twenty Eight.

Friendly Attentions.

A peculiar pale light played and flashed from the surface of the black water which was being churned up by the desperate struggles of the drowning pair. It was as if myriads of tiny stars started into being where all was dark before, and went hurrying here and there, some to the surface, others deep down into the transparent purity of the sea.

A minute before Jem Wimble had kept command of himself, and swam as a carefully tutored man keeps himself afloat; that minute passed, all teaching was forgotten in a weak, frantic struggle with the strangling water which closed over their heads.

A few moments, during which the phosphorescent tiny creatures played here and there, and then once more the two helpless and nearly exhausted fugitives were beating the surface, which flashed and sent forth lambent rays of light.

But it was not there alone that the phosphorescence of the sea was visible.

About a hundred yards away there was what seemed to be a double line of pale gold liquid fire changing into bluish green, and between the lines of light something whose blackness was greater than the darkness of the sea or night. There was a dull low splashing, and at every splash the liquid fire seemed to fly.

The double line of fire lengthened and sparkled, till it was as so much greenish golden foam reaching more and more toward where the drowning pair were struggling.
