You have no comprehession of of our federal land division system.
Well, I have some comprehension, but I will defer to your experience and knowledge. I did look up the Land Ordinance before I replied and got the impression that while he served on the committee, that the committee decided on a variation used in Western New England. Certainly the scientific way of surveying land would appeal to Jefferson. I live in MO and my property is described as it would have been using the Ordinance. But I live near KY and their land surveying system is a holy mess compared to ours.

Jefferson was the only man sufficiently educated in Math, geodessy, and physics at the time to devise such a system.
