edoed off a point in the English Channel. A
torpedo fired into her hull failed to sink her immediately, and a
Norwegian ship came to her aid, passing her a cable and attempting to
tow her to port. But the submarine returned, and fearing attack, the
Norwegian ship made off. A second torpedo fired at the _Dumcree_ had
better effect than the first one, and she began to settle. When the
submarine left the scene the Norwegian steamship again returned to the
_Dumcree_ and managed to take off all of her crew and passengers.
Three trawlers, one of them French, were sunk in the same neighborhood
during the next forty-eight hours.

As soon as Italy entered the war an attempt was made by the Teutonic
Powers to establish the same sort of submarine blockade in the
Adriatic which obtained in the waters around Great Britain. This was
evinced when the captain of the Italian steamship _Marsala_ reported
on May 21, 1915, that his ship had been stopped by an Austrian
submarine, but the latter not wishing to disclose its location to the
Italian navy, allowed his ship to proceed unharmed.

The suspicion that the German admiralty maintained bases for their
submarines right on the coasts of Great Britain where the submersible
craft could obtain oil for driving their engines, as well as supplies
of compressed air and of food for the crew, was confirmed on the 14th
of May, 1915, when it was reported that agents of the British
admiralty had discovered caches of the kind at various points in the
Orkney Islands, in the Bay of Biscay, and on the north and west coasts
of Ireland.

In order to damage shipping in the "war zone" by having ships go wrong
through having no guiding lights an attack was made by a German
submarine on the lighthouse at Fastnet, on the southern coast of
Ireland, on the night of May 25, 1915. Shortly after nine in the
evening the submarine was sighted in the waters near the lighthouse by
persons on shore. She was about ten miles from Fastnet, near Barley
Cove. When she came near enough to the lighthouse to use her deck
guns, men on shore opened fire on her with rifles, and she submerged,
not to reappear in that neighborhood again.

But this same submarine managed to do other damage. The American
steamship _Nebraskan_ was in the neighborhood on its way to New York.
The sea was calm and the ship was traveling at 12 knots, when some
time near nine o'clock in the evening a shock was felt aboard. A
second later there came a te
