William Strong, The Pennsylvania — Opinion of the Court
“ She was constantly changing her position. It was her duty, therefore, to blow a foghorn, and not to ring a bell. By ringing a bell, as she did, she gave a false signal, and, so far as she could, assured all approaching vessels that she was not under way. There is some evidence that a bell can be heard as far as can a foghorn, and some that it can be heard farther. On the other hand there is evidence that a foghorn can be heard farthest. However this may be the bark had no right to substitute any equivalent for the signal required by the navigation rules. ”
