Joseph Story,
Ellicott v. Pearl — Opinion of the Court
“ The reason why a survey, made by a public surveyor in discharge of his public duties, is admitted as evidence in suits between other parties, is, not that it is hearsay; but that the act is officially done under oath, and in discharge of his duties to the government and the public. But it has never been supposed, that if in such a survey the surveyor should go on to state collateral facts, or declarations of the parties, or other matters, not within the scope of his proper official functions; he could thereby make them evidence as between third persons. ”
