ss, reason, justice, and humanity which all modern
opinion regards as imperative. It is practically impossible for the
officers of a submarine to visit a merchantman at sea and examine her
papers and cargo. It is practically impossible for them to make a prize
of her; and, if they cannot put a prize crew on board of her, they
cannot sink her without leaving her crew and all on board of her to the
mercy of the sea in her small boats. These facts it is understood the
Imperial German Government frankly admit. We are informed that in the
instances of which we have spoken time enough for even that poor measure
of safety was not given, and in at least two of the cases cited not so
much as a warning was received. Manifestly, submarines cannot be used
against merchantmen, as the last few weeks have shown, without an
inevitable violation of many sacred principles of justice and humanity.

American citizens act within their indisputable rights in taking their
ships and in traveling wherever their legitimate business calls them

well-justified confidence that their lives will not be endangered by
acts done in clear violation of universally acknowledged international
obligations, and certainly in the confidence that their own Government
will sustain them in the exercise of their rights.

travel upon the seas would do so at his peril if his journey should take
him within the zone of waters within which the Imperial German Navy was
using submarines against the commerce of Great Britain and France,
notwithstanding the respectful but very earnest protest of his

for the purpose of calling the attention of the Imperial German
Government at this time to the surprising irregularity of a
communication from the Imperial German Embassy at Washington addressed
to the people of the United States through the newspapers, but only for
the purpose of pointing out that no warning that an unlawful and
inhumane act will be committed can possibly be accepted as an excuse or
