Cooley's statement, from Diehl v. Zanger (1878), captures the single most important principle in boundary retracement: the original monuments — the stakes actually set by the original surveyor — control the boundaries, even if a modern, more accurate survey would place them elsewhere.

The reason is that the lots came into legal existence when they were created and sold by reference to those original stakes. Purchasers took, built on, and occupied their land relative to the monuments on the ground, not relative to an abstract mathematically perfect grid. The original survey, with all its imperfections, is the survey that made the parcels; a later "correct" survey does not unmake the reliance that has grown up around the original marks. To move a boundary to where a perfect survey says it "should" be would disturb every occupation established in good faith on the original stakes.

In practice, the surveyor therefore does not set out to make a new and better subdivision. The task is retracement — to follow in the footsteps of the original surveyor and recover, from the best available evidence, where the original monuments were placed. Found original monuments (or their proven positions from corroborating evidence — occupation, fences, testimony, ties) govern over the record measurements. Only where an original monument is genuinely lost does the surveyor fall back on measurement, and even then he reconstructs the original position (for example by proportioning) rather than imposing a fresh, "accurate" location.
