In this case it is, difficult to see how the Russian ship Sylfid, which, at the instance of and for the benefit of the libelants, was taken possession of by the harbor master and moved from its dock, can be held liable to the libelants for any collision which resulted from or followed such moving; and we agree with the trial judge that there was not sufficient evidence to establish negligence or fault against the pilot. The decree of the District Court (169 Fed. 995) is affirmed.
