Chaining in the old days..How close??
I have seen on this board, now and then, folks saying that the old chaining was OK back then, but nowhere close to what it measures today...
Here's a few snippets of some chaining and todays electronic wonders..
A length was chained and after temperature and tension corrections the distance was recorded as 1120.345'
Using the ties and control on the north end of that line, a spike and washer was placed at an intersection.
Recovering the south end of the line and measuring to the spike and washer set in 1982, the electronic wonder did prove that the chaining of 1949 was incorrect...it measured 1120.349'
Is this a case of material discrepency??
