'Alia that of the subassistants was at the rate of $10 per month. None 

 of the officers received salaries from other institutions. 



Results. — According to Professor Branner, Doctor Owen's efforts 

 were devoted entirely to the work of reconnaissance, the first report 

 treating the region north of the Arkansas River, and tlie second that 

 south of the river. In the main his ideas of the geological structure 

 of the State were correct, and his facts have been of great service in 

 working out the details of the structure and the areal geology. 

 Errors were made, but they were few and unimportant, especially 

 when we take into consideration the limited time and small means 

 at the disposal of the survey. It may be well (quoting Doctor Bran- 

 ner) to mention the more fundamental of these errors, because they 

 have so long been current : 



1. It was thought that the Arkansas coals belonged to the Lower 

 Coal Measures. Coal does occur in the Lower Coal Measures north 

 of the Boston Mountains, and the generalizatio]\ was made from 

 these beds. The coal of the Arkansas Valley is in an altogether dif- 

 ferent position — near the top of the Coal Measures. 



2. It was thought that the novaculites. now known to be Silurian, 

 were Carboniferous. No fossils had th.en been found in or near the 

 novaculites. 



3. The theory of northeast-soutliwest metalliferous veins across the 

 State, although advanced only as '* probable," led to much searching 

 for silver and lead, much loss of time and money, and to much dis- 

 appointment. 



The Civil War broke out shortly after the publication of Owen's 

 second report, and tlie survey was discontinued through the follow- 

 ing act: 



An act to rtpoal tbo ono hundred and sixty-eightb cliapter of Gould's Digost. 



Skction 1. Be it enacted by the General Assemhly of the dtate of Arkansas, 

 That the law providing for the appoiutment of n gelogist of this State, and for 

 a geological survey of this State, as px'ovided for by chapter 168 in Gould's 

 Digest, be, and the same is hereby repealed: and that this act take effect and 

 be in force from and after its passage. 



Approved, January 21, 1861. 



The books and specimens collected during the period of these sur- 

 veys were disposed of according to the following : 



An fict for tlie bt-nefit of St. John's College. 



Be it enacted by the General Assembly of the Slate of Arkansas, That the 

 geological and niinera logical specimens on deposit in the office of the secretary 

 of state be turned over to St. John's College and placed in its cabinet, for the 

 use of the faculty, students, and others, and that the miscellaneous books on 

 deposit in the office of the seci'etary of state be turned over to the said college, 

 to be placed in their library for the use of the faculty, students, and others:
