Question: Ordinance of 1830

I'm trying to find out where I can find the government notes for the laying out of townships (establishing townships) as per the federal ordinace of 1830 for Delaware County, Indiana. This is for a Land Surveying company in Muncie, Delaware County, Indiana and we've tried the Delaware County Building which holds the Auditors Office, Recorders Office, and the County Surveyors Office, but to no avail. Please help if you can, if not, I understand. Thanks!
