“There’s a life preserver in the water!” Dick could see it without glasses. Sandy looked.

“The amphibian is making for it!” he yelled.

“The hydroplane can’t get there in time!” shouted Larry.

None of them realized that Jeff’s roaring engine drowned their cries.

“Jeff! Look——” Wildly Sandy gesticulated.

Fast and high, in a swift glide, coming like a hawk dropping to its prey, a light seaplane, skimming the edge of an incoming fog bank, showed its slim, boatlike fuselage and wide wingspan, with two small pontoons at wingtips to support it in the surf.

There was a swift drop of their own craft as Jeff dived, came into a good position and zoomed past the yacht, close to it.
