John McLean, Bissell v. Penrose — Dissent
“ If the two surveys made by Mackay of 800 arpens each, 'for the proprietor,' were admitted to have been made at the instance of Tillier, it leaves the location of the concession uncertain. Both surveys were executed on the same day, and were recorded on the same page. Under Tillier's right, he could survey only 800 arpens; and if he surveyed two tracts each of that quantity it was a fraud upon the public. Under the acts of Congress no tract of land was reserved as a Spanish claim, which was not surveyed or so specifically designated as to show with reasonable certainty its boundaries. ”
