302 THE IRON ORE DISTRICT OF EAST TEXAS. 



Algiers, the earthquake mentioned must have occurred about the same time 

 as those above described, from which it may be inferred that the centre of 

 disturbance was in the eastern hemisphere, and the vibrations observed in 

 the western hemisphere were simply due to reaction. 



CONCLUDING REMARKS. 



The writer desires to express his thanks to public spirited citizens of Rusk 

 and New Birmingham for courtesies during his short stay in their midst. 

 Among others, he met Mr. A. Jackson, who at a Democratic convention held 

 at Jacksonville, in 1856 (which was addressed by Rusk, Wigfall, and others), 

 introduced a resolution, framed by Mr. M. H. Bonner, calling for legislative 

 action to organize a State Geological Survey. To Mr. Jackson and Mr. 

 Bonner therefore belongs the credit of probably the first public action looking 

 to the establishment of a State survey. 



The writer is indebted to Mr. N. F. Drake, Assistant Geologist, for his aid 

 in preparing the map of the oil regions of Nacogdoches, and the various 

 figures accompanying this report, for the photo-engraver.
