“And while in the cold pale light of that Tuesday morning in the North
the salvors sent down divers to call in friendly Morse upon their
comrades below, and to cheer them with the assurance of rescue, the
unexpected happened again, as it always does at sea. Suddenly before
the astonished eyes of the salvage party up shot a column of foam

up-ended and pulled clear of the water. Involuntarily, without the
smallest intention of quitting, Commander Herbert had been boosted by
the ill-mannered high-pressure air out of his own ship, and flung, a
bedraggled, gasping figure, in shirt and trousers, almost into the arms
of his would be rescuers. How he came out I will now tell, and in doing
so will return to 3.30 p.m. on the Monday when _K-13_ settled down in
the mud of the Gareloch.
