Administrative Keipiort. The work done was largely that assigned him in 
the letter of instruotions from the State Geologist: “The work to which 
you are assigned for the present is the continuation of the mapping of the 
iron lore deposits of Eastern Texas. You will, therefore, proceed to iCass 
county, which is now partially finished, and complete it. Then malce recon- 
noissance of Bowie to determine amount of iron in that county. 
“In addition to the mapping of these ores, you will make such observa- 
tions in the clays and lignites as you are able to do, thus preparing your- 
self to take up their study in detail as soon as the present work is com- 
pleted.” 
The proposed reoonnoissance into Bowie county was abandoned, as it 
was soon ascertained “that the existence of iron ore in that eounty was 
problematic.” The iron ores of Harrison eounty were also examined and 
mapped, and the clay and lignite exposures visited, after which a few days 
were spent in the vicinity of Jefferson, Marion county, investigating clay 
and green sand marl deposits. General geologic and topographic notes 
were taken in conneGtion with all the work.

“The iron ore region of Cass county extends in a general though somewhat 
irregular course from the southwest end of the eounty to the northeast. 
In the southwest it covers a roughly shaped parallelogram extending along 
the lower half of the Morris county line southward to the Marion county 
line, thence eastward along the northern boundary of Marion county for 
several miles to near the oros,sing of the Texas and Pacific Bailway. From 
the northeast corner of this parallelogram a long, narrow, irregularly 
shaped tongue or ridge extends northeasterly to near the town ef Atlanta, 
when it widens out into a rude sort of a triangle, having its northern side 
somewhat parallel to the course of the Sulphur Fork of the Bed Biver.”
