AMERICAN GEOLOGY DECADE OF 1830-1839. 307 



pared, even to the drawing- on stone, by himself. Nos. 1 and 2 appeared 

 in 1832, and Nos. 3 and 1 in 1833. These editions early became ex- 

 hausted, and in L893 a new edition was prepared through the instru- 

 mentality of Doctor Harris. It will be well to mention here that a 

 second edition of his Medial Tertiary fossils was brought out this 

 same year by Dr. W. H. Pall, working in conjunction with the Wag- 

 ner Free Institute of Philadelphia. 



The work of 1832-33 contained little of a strictly geological nature, 

 being mainly devoted to a description of the various fossil inverte- 

 brates belonging to the Tertiary formations. Conrad divided the 

 Tertiary, in conformity with the English custom, into an Upper Marine 

 formation, a Middle Tertiary formation, and a Lower Tertiary for 

 mation, and gave the geographic extensions of each so far as they are 

 known. 



In 1830 the legislature of Massachusetts passed a resolve authorize 



ing the appointment of a surveyor to make a general surve} r of the 



Commonwealth, and on the fifth of June following, on the recommen. 



dation of Governor Lincoln, further authorized the 



Hitchcock's Survey . • i i i. •

connection with this survey, a geological examination 

 of the region involved. On February 2, 1831, the limits of the geolog- 

 ical survey were extended so as to allow tin 1 inclusion in the report of 

 a list of the mineralogical, botanical, and zoological productions. 



Prof. Edward Hitchcock, then professor of chemistry and natural 

 history in Amherst College, was selected as the "suitable person," and 

 presented,, early in 1832, a report of 72 pages, with a colored geolog- 

 ical map, on the economic geology of the State. Of this 600 copies 

 were ordered printed. In the early part of 1833 reports on the topo- 

 graphic geology (37 pages), scientific geology (130 pages), and the cat- 

 alogues of animals and plants, with an appendix containing a list of 

 the rocks and minerals described (248 pages), were likewise submitted. 



The legislature promptly accepted these reports likewise and ordered 

 the printing of 1,200 copies, including a reprint of the report first 

 made. Altogether these formed an octavo volume of 692 pages, with 

 numerous figures in the text, and a folio volume of 19 plates, includ- 

 ing a colored map. The publication of this report marks an epoch in 

 American geological work, since it brought to a successful conclusion 

 the first survey of an entire State at public expense/' It is true that 

 spasmodic beginnings had been made in North and South Carolina, 

 but such were so lacking in breadth of conception and failed so utterly 

 in execution that it is only by courtes\ r that they can be considered as 

 geological surve} T s at all. Under these conditions a detailed review of 

 the contents of the reports will not be out of place here. 



«The total expense to the State of the three years' work, exclusive of cost of 

 printing, was $2,030.
