GEOLOGICAL AND NATUEAL HISTOBY SURVEYS. 433 



tude of more tluin 3 miles Ava;s concentrated from east and ^Yest along 

 the line of the Susquehanna Eiver, and was then redistributed east- 

 ward and westward toward the New Jersey and Ohio State lines. 

 Had it not been for the small scale on which the State map was 

 drawn (5 miles to the incli) the distortion of the geological out- 

 crops, colored to represent the formations, would have been flagrant. 



Museums. — Section 5 of the act of 1836 directed the State geologist 

 to make collections of rocks, ores, coals, soils, fossils, and mineral 

 products in order to form a complete cabinet of specimens, which the 

 secretary of the Conmionwealth should cause to be deposited in proper 

 order in some convenient room in the State capitol. He was further 

 directed to furnish similar specimens of the geology and mineralogy 

 of each county in the State to the commissioners of said county, who 

 should cause the same to be properly deposited in a room of the 

 county courthouse or some convenient place for public inspection. 

 Tlie act of 1840 authorized the preparation of three complete col- 

 lections " for the use of the State." An act of 1848 provided : 



That on application to that effect the secretary of the Commonwealth be 

 directed to deposit with the "Western Pennsylvania University of the city of 

 Pittsburgh, the fourth collection of geological and mineralogicnl specimens now 

 in Phihidelphia, which said fourth collection as made by Professor Rogers 

 from the principal collections originally deposited in Harrisburg and Philadel- 

 phia shall in lio maimer be disturbed or impaired by such deposit at Pitts- 

 l)urgh. 



Resolved, That the collection of geological and mineralogical specimens col- 

 lected by Professor Rogers to be deposite<l in Philadephpia, and which is now 

 stored in that city be, and the same is hereby, presented to the corporation of 

 the city of Philadelphia, on condition that the said corporation shall, within 

 one year, deposit the same in some public building or public institution in 

 TMiiladelpliia, where it shall be duly arranged in scientific order, and marked 

 as the collection made by the State, and be kept open at all proper times for 

 public inspection, free of charge. 



Expenses. — The total appropriations for the survey, including those 

 of the supplementary acts for its completion, amounted to $06,000, 

 exclusive of the cost of preparation of manuscript and the publication 

 of the final report. 



Publications. — During the period of its existence the survey issued 

 six annual reports, the first bearing date of 1836 and the last 1842. 

 These were small octavo volumes, destitute of illustration, with the 

 exception of a few outline sections, and of 100 to 250 pages each. 



The survey, as noted, came to an untimely end in 1842. Rogers, 

 liowever, being unwilling to relinquish the work in its unfinished con- 

 dition, continued at his own expense until he was able, in 18-17, to 

 make his fmal report to the office of the secretary of the Common- 

 wealth. Here the manuscript was allowed to lie until, in the spring 

 of 1851, appropriations, which were continued until 1855, were made
