I was looking at some sketches and field notes in far southwest Texas - not far from Terlingua. Fairly tough territory with minimum vegetation. Robert S. Dod was engaged in retracing the original GCSF Ry surveys around 1910 and submitted a couple of interesting items including one detailing the rigors of surveying in the area. He also submitted a sketch (Brewster County Rolled Sketch 24B) with Hebrew notation on the lower right corner. The General Land Office provides a translation from Abraham Zilkha, University of Texas 1989 in the map notes.
"There was chaos upon the face of the Earth."
Sounds like it was a difficult survey.

Geez, the internet is amazing. I know now why the surveyor was able to annotate his map with Hebrew script. http://archive.episcopalchurch.org/109399_12605_ENG_HTM.htm He was an episcopal minister. Moved to Texas for health reasons. An article in The Amsterdam Daily Democrat (4/8/1885) reports that he was a good Hebrew scholar, a mathematician and a machinest. He helped set up a new monastic order but then moved to Texas on account of asthma.
5th column titled "A New Monastic Order".
That part of Texas has a "beauty" all its own...

We tend towards scholars, that's for sure.
