memories--memories tender, wistful and pathetic, entangled as in
tears and fire. All the inward instincts of my spirit told me that I
knew him well--as well as one knows the gold of the sunshine or the
colour of the sky,--yet where had I seen him often and often before?
While my thoughts puzzled over this question he averted his gaze
from mine and went on speaking to Catherine.

"I understand," he said--"that you are interested in the lighting of
my yacht?"

"It is most beautiful and wonderful,"--answered Catherine, in her
coldest tone of conventional politeness, "And so unusual!"

His eyebrows went up with a slightly quizzical.

"Yes, I suppose it is unusual," he said--"I am always forgetting
that what is not quite common seems strange! But really the
arrangement is very simple. The yacht is called the 'Dream'--and she
is, as her name implies, a 'dream' fulfilled. Her sails are her only
motive power. They are charged with electricity, and that is why
they shine at night in a way that must seem to outsiders like a
special illumination. If you will honour me with a visit to-morrow I
will show you how it is managed."

Here Captain Derrick, who had been standing close by, was unable to
resist the impulse of his curiosity.

"Excuse me, sir,"--he said, suddenly--"but may I ask how it is you
sail without wind?"
