were also made to close by explosions the tunnels through which
the Canadian Pacific Railroad passes under the Selkirk Mountains in
British Columbia. The German General Staff in this instance operated
through Franz Bopp, the German consul-general in San Francisco, and
Lieutenant von Brincken. J. H. van Koolbergen was hired to do this work.
Concerning the negotiations, van Koolbergen made this statement:

"Not knowing what he wanted I went to see him. He was very pleasant and
told me that he was an officer in the German army and at present working
in the secret service of the German Empire under Mr. Franz Bopp, the
Imperial German consul.

"I went to the consulate and met Franz Bopp and then saw von Brincken in
another room. He asked me if I would do something for him in Canada and
I answered him, 'Sure, I will do something, even blow up bridges, if
there is money in it.' And he said, 'You are the man; if that is so, you
can make good money.'

"Von Brincken told me that they were willing to send me up to Canada to
blow up one of the bridges on the Canadian Pacific Railroad or one of
the tunnels. I asked him what was in it and he said he would talk it
over with the German consul, Bopp.

"I had accepted von Brincken's proposition to go to Canada and he
offered me $500 to defray my expenses. On different occasions, in his
room, von Brincken showed me maps and information about Canada, and
pointed out to me where he wanted the act to be done. This was to be
between Revelstake and Vancouver on the Canadian Pacific Railroad, and I
was to get $3,000 in case of a successful blowing up of a military
bridge or tunnel."

Van Koolbergen only made a pretended effort to blow up the tunnel. He
did furnish the evidence, however, which served to send Bopp and his
associates to the penitentiary.

Even more sensational was the plot against the international bridge upon
which the Grand Trunk Railway crosses the border between the United
States and Canada at Vanceboro, Me.

Werner Horn was a German reserve lieutenant. Von Papen delivered to him
a flat order to blow up the bridge and he gave him $700 for the purpose
of perpetrating the outrage. Horn was partially successful. At his trial
in Boston in June, 1917, he made the following confession:

"I admit and state that the facts set forth in the indictments as to the
conveyance of explosives on certain passenger trains from New York to
Boston and from Boston to Vanceboro, in the
