collection, with reference to the field notes, and to the name or 

 designation under which the specimens of fossils appeared in the 

 report of 1860. 



Expenses. — Satisfactory statistics bearing upon the expenses of 

 the survey are not available. So far as can be determined by the 

 reading of the various acts establishing the survey and making the 

 appropriations, they were approximately as follows : 



By act of March 5, 1850, $3,000 a year for seveu years $21, 000 



By act of 1852, for museum 200 



By act of 1854, for publication 2, 500 



By act of 1857, for laboratory 1,200 



By act of 1860, for laboratory 545 



By act of 1860, for publication 3,500 



Total appropriations $28, &45 



Salaries. — Under Professor Millington, the assistant geologists 

 were paid $1,000 each, annually. Professor Hilgard, under Harper, 

 received at first $1,000, which was later increased to $1,500 annually. 

 Professor Harper's salary is given as having been $2,000 annually. 



Publications. — The official reports of the several surveys were com 

 prised under five reports nnd a circular announcing the resumption 

 of work in 1866. 



Wailes's report (the first of the Mississippi geological reports), 

 of which the publication was provided for by the law of 1854, bears 

 the imprint of E. Barksdale, State printer, 1854, but was actually 

 printed at Philadelphia, where Wailes remained during the greater 

 part of 1854 to superintend its passage through the press. The 

 volume is an octavo of 371 pages, with 17 illustrations, partly of a 

 historical character, partly referring to the cotton industry. Eight 

 of these illustrate geological subjects, the most important being 

 four plates of shells from the Jackson shell bed, named and de- 

 scribed by Conrad. The report begins with a " historical outline," 

 covering 125 pages; a treatise on the agriculture of the State, partly 

 historical and dealing largely with cotton culture, followed by some 

 analyses of marls, cotton, ashes, and mineral waters, and covering 

 81 pages ; meteorological data, 12 pages ; lists of fauna and flora, 46 

 pages: appendices, with documents, 25 pages. This summary is 

 sufficiently indicative of the fact that Wailes was not and did not 

 write as a specialist in any department. He m.ade no attempt to 

 classify the rocks he described otherwise than as Cretaceous, Terti 

 ary, and Quaternary, and inferentially classed among the latter 

 the sandstone of the Grand Gulf group, which is mentioned as over- 

 lying " diluvial gravel." He traced correctly the northern limit 

 of the Grand Gulf rock'-' from the Mississippi, across Pearl River
