a spur or ram. At the after end were two flickering, interlacing circles
of a glittering greenish-yellow colour, apparently formed by two
intersecting propellers driven at an enormous velocity. Behind these was
a vertical fan of triangular shape. The craft appeared to be
flat-bottomed, and for about a third of her length amidships the upper
half of her hull was covered with a curving, domelike roof of glass.

"She's an air-ship of some sort, there's no doubt about that," said the
Captain, "so I guess the great problem has got solved at last. And yet
it ain't a balloon, because it's coming against the wind, and it's
nothing of the aeroplane sort neither, because it hasn't planes or kites
or any fixings of that kind. Still it's made of something like metal and
glass, and it must take a lot of keeping up. It's travelling at a pretty
healthy speed too. Getting on for a hundred miles an hour, I should
guess. Ah! he's going to speak us! Hope he's honest."

Everybody on board the _St. Louis_ was up on deck by this time, and the
excitement rose to fever-heat as the strange vessel swept down towards

depth and thirty of beam, and the Captain and many of his officers and
passengers were very much relieved to find that, as far as could be
seen, she carried no weapons of offence.

As she ranged up alongside, a sliding door opened in the glass-domed
roof amidships, just opposite to the end of the _St. Louis'_ bridge. A
tall, fair-haired, clean-featured man, of about thirty, in grey
flannels, tipped up his golf cap with his thumb, and said:

"Good morning, Captain! You remember me, I suppose? Had a fine passage,
so far? I thought I should meet you somewhere about here."

The Captain of the _St. Louis_, in common with every one else on board,
had already had his credulity stretched about as far as it would go, and
he was beginning to wonder whether he was really awake; but when he
heard the hail and recognised the speaker he stared at him in blank and,
for the moment, speechless bewilderment. Then he got hold of his voice
again and said, keeping as steady as he could:

"Good morning, my Lord! Guess I never expected to meet even you like
this in the middle of the Atlantic! So the newspaper men were rig
