John McLean, United States v. Boisdoré, 52 U.S. 63…
“ Elihu Carver, who says that he is a practical surveyor, on being asked how he would survey a Spanish concession which calls for two points as the front upon the sea-shore or a water-course, and calls to run in depth to another water-course for quantity, answers "that he would run from one of the first points back to the watercourse a distance equal to the front given, thence direct to the last point in the front." He says that he has surveyed many Spanish claims, and, except one, he never found the boundaries all round. ”
