features brought out. The work as :i whole is an extremely uninter- 

 esting array of details, essential to the geographical extension of geo- 

 logical knowledge. Some space was devoted to economic geology, a 

 consideration of soils, etc. Doctor Litton's report consisted almost 

 wholly of details of lead, copper, and iron mines. Perhaps the most 

 important economic item in Meek's report was his calling attention 

 to the limited area of the coal beds, which lie in narrow basins in the 

 encrinal limestone. 



The third annual report of progress (6 pages) appeared in 1857, 

 the fourth (14 pages) in 1859, and the fifth (19 pages) in 1861. G. C. 

 Broadhead, who later was himself State geologist, became an assistant 

 during 1857-1861, J. G. Norwood in 1858-1861, Henry Engelmann in 

 1857, and Dr. John Locke in 1860. 



During the period which intervened between the publication of the 

 second report and the stopping of the survey in 1861, a large portion 



of the State had been visited by members of 

 the corps, and full reports were written on 

 the following counties: Cape Girardeau, 

 Perry, St. Genevieve, Jefferson, Crawford, 

 Phelps, Pulaski, Laclede, Wright, Ozark 

 (including Douglas), Clark, Morgan, Miller, 

 Saline, Chariton, Macon, Randolph, Shelby, 

 Osage, and Maries. 



After the survey had been discontinued 

 the legislature authorized L. D. Morse and 

 G. C. Swallow to publish all the results of 

 the work of the previous seven years, but 

 the project was abandoned on account of 

 the expense. 



While nearly all the State and land-office 

 surveys organized up to 1850 had economic ends in view, and while, 

 further, numerous papers of a more or less economic character had 

 appeared from the. hands of various writers from time to time, yet 

 j. D.Whitney's literature relating to American ore deposits remained 

 tn^united states J scant and of an extremely unsatisfactory character.

Wealth of the United States marked, therefore, an important epoch. 

 The work comprised upward of 500 octavo pages, and though writ- 

 ten with especial reference to the ore deposits of the United States, 

 contained references to those of all the principal foreign localities as 

 well and remained the standard work of reference up to the time of 

 the appearance of Kemp's Ore Deposits of the United States in 1893.
