GEOLOCUCAIv AND NATl'KAL HISTORY SLTliVEYS. ^ 



In 1801, or before the expiration of the lO-xear limit lueiitioned in 

 Section 4 aboA^e, the amount of the annual appropriation was in- 

 creased to $7,500. this amount to continue until otherwise ordered by 

 the ^roneral assembly, the purport of the bill being to avoid the neces- 

 sity of rencAved legislation at every session. Under these laws assist- 

 ants were appointed and assignments made as follows: 



Personnel. — Henry McCalley to ^^•ork in the Warrior coal field and 

 the valley regions; Joseph Squii-e, in the Caliaba coal field; A. M. 

 Gibson, in Murphree's Valley and the coal measures adjacent thereto, 

 and afterward in the Coosa coal field. Doctor Smith, with D. W. 

 Langdon, T. H. Aldrich, and L. C. Johnson, undertook the examina- 

 tion of the Cretaceous and Tertiary formations of the Coastal Plain, 

 although a large part of the time of the director was occupied in ad- 

 ministrative and editorial work. Later Dr. George Little made an 

 examination of the clays of the Lower Cretaceous: Dr. W. !>. 

 Phillips began an investigation of the gold region, which. Avas con- 

 tinued by W. M. BreAver; and K. M. Cunningham demonstrated the 

 existence of true chalk deposits in the Alabama Cretaceous. 



Jfefhodt; and results. — The results accomplished u.p to 1000, giA-en 

 in Doctor Smith's summary, are as folloAvs: 



McCalley "s report on the Warrior coal field, published in ISSC). con- 

 tained detail sections of all the exposures of coal seams in the basin 

 division of this field, together Avith Mr. Gibson's account of part of 

 the plateau diAdsion. This report also contained the first approxi- 

 mately full columnar section of the measures of this field. McCal- 

 ley's report on the plateau region of the Warrior field, Avith map ?am\ 

 colored section, appeared in 1891. 



SOjUire's report and map of the Cahaba coal fi.eld appeared in ISOO. 

 The document purports to be the outcome of some 30 years' Avorl:. 

 during which time Mr. Squire had been continuously engaged in this 

 field, either in. actiA^e mining or in making instrumental surveys for 

 individuals or corporations, all the results of Avhich Avere incorporated 

 in his report. The map, it is claimed, showed accurately the surface 

 outcrops of all the important seams of coal and a numl)er of carefully 

 constructed A-ertical and horizontal sections of the field. It exhibited 

 also the geology of the adjacent valleys. 



The existence of ])hosphatic nodules and marls in the State Avas 

 discoA-ered in 1884. The distribution, quality, and quantity of these 

 were iuA'estigated by ]Mr. Langdon and the director, tlie repoi-t of 

 progress being incorporated in Bulletin No. 2, 1802. Mr. (libson's 

 report on the geology and resources of ^Murphree's Valley did not itp- 

 pear until 1803. His repoil on the coal measures of Blount ^lountain 

 was issued in 1804. and hi- ])r('iiniiii;!i'y report on the Coo-a cojil field 

 in 180.-).
