THE GEOLOGICAL SURVEYS OF ARKANSAS. 



835 



13. Analyses and distribution of the zinc ores. 

 Some of the more comprehensive geologic problems that yet 

 remain to be solved, relate to : 



1. The palaeontology of the state. 



2. The physical geography. 



3. Quaternary history. 



4. Relation of the palaeozoic beds to those of the other parts 

 of the continent and to those of the world. 



5. The divisions of the Silurian beds. 



Resume of Appropriations and Publications. 



Engraving, printing, and binding are not included in the total 

 for the period 1887-95. Those items and the cost of fuel, lights, 



1 No field work was done after 1892; the appropriation was made in 1893 for 

 completing the reports. 



2 A deficiency bill for $2,340 was passed by the legislature in 1889. This sum, 

 however, should not be added to the total amount appropriated because a somewhat 

 larger amount reverted to the treasury that year from the appropriation for salaries. 

 It is but just to add, moreover, that the work represented by the state geological 

 reports was not all paid for by the state : about $8000 worth of work was contributed 

 by volunteer assistants ; about $5000 was spent on precise levels by the U. S. Coast 

 and Geodetic Survey; about $25,000 was spent in topographic work by the U. S. 

 Geological Survey ; about $7000 worth of engraving was done by the U. S. Geological 

 Survey, and a deficiency of about $3000 was paid by the State Geologist.
