Charles Evans Hughes, Pigeon River Improvement Slide Boom Company v…
“ No question is raised as to reasonableness or discrimination, the only question being whether in the light of the provision of the treaty any tolls whatever could be charged. The contentions of the defendant are that the Pigeon river is a boundary stream and, as one of the 'water communications' described in the treaty, must be kept 'free and open' to the use of the citizens and subjects of both countries; that the imposition of tolls is inconsistent with this stipulated immunity and is not justified by the legislation which the Pigeon River Company invokes. ”
