David Josiah Brewer,
Casement v. Brown — Opinion of the Court
“ If it was a natural obstruction, one in respect to which no party had any duty of preservation or warning, it might be that the obligation resting upon the pilots would be of a different and more stringent character. But they knew that here a great work was being constructed by these defendants; that it was their duty to give all needful warning to persons and boats going up and down the river; and that, if there were no buoys in place, or other warning given, they might fairly conclude that all of these piers were so far submerged as to threaten no danger to passing boats. ”
