it a creation of the heart-felt wishes of so many?

Perhaps a warning to every one that at that moment the ship had gone
to the bottom? The sea always sends word of its evil doings; when
the bread-winner is taken his family hear a shutter creak, or three
taps on the windows that look on to the sea--there are so many ways.

But now it sounded again, and this time the sound come in little
waves over the water, the same vibrating, subdued whistle that
long-tailed ducks make when they rise; it seemed alive. The fog-horn
answered it out in the fairway, and the bell in at the mole-head;
then the horn once more, and the steam-whistle in the distance. So
it went on, a guiding line of sound being spun between the land and
the indefinite gray out there, backward and forward. Here on terra
firma one could distinctly feel how out there they were groping
their way by the sound. The hoarse whistle slowly increased in
volume, sounding now a little to the south, now to the north, but
growing steadily louder. Then other sounds made themselves heard,
the heavy scraping of iron against iron, the noise of the screw
when it was reversed or went on again.

The pilot-boat glided slowly out of the fog, keeping to the middle
of the fairway, and moving slowly inward hooting incessantly. It
towed by the sound an invisible world behind it, in which hundreds
of voices murmured thickly amidst shouting and clanging, and
tramping of feet--a world that floated blindly in space close by.
Then a shadow began to form in the fog where no one had expected it,
and the little steamer made its appearance--looking enormous in the
first moment of surprise--in the middle of the harbor entrance.
