He commented that this was a "Happy little accident".
Since then he has contacted me to let me know that these "special instructions" do appear in the 1879 Annual Report of the Commissioner of the General Land Office (on pages 10-12), in a circular dated July 27, 1878. He also asked if he could send a copy of the document to the BLM office in Washington, D.C. because they were not aware of individual territories putting out these types of publications.
I'm always glad when things work out and am very glad that this "happy little accident" occurred to make us more aware of these types of documents and how they are still being used today. We are still looking for Special Instructions for U.S. Deputy Mineral Surveyors in the District of Montana for the Establishment of Corners, etc. If you happen to know where a copy exists, please let us know.
