PabPACE TO SECOND EDITION (NEW SERIES). 
It being necessary to publish a new edition of the Reports 
of the Geological Survey, it is thought proper to change the 
arrangement of the reports in the several volumes. This is 
advisable in order to bring together in one volume the several 
reports relating to a given subject or locality. In the first 
edition (second series) the volumes were made up of reports, 
regardless of subjects treated, and in order to learn all that 
may be published of a locality, the reader must examine sev- 
eral volumes. For instance, the reports on the iron ores and 
the iron manufacture of Greenup, Carter, Boyd, and Lawrence 
counties is in volume 1, and the Report on the Geology of the 
above named counties is in volume 2. The Chemical Reports 
nd the reports on the Timbers are scattered through four 
a 
Be otumes. This arrangement of reports could not have been

avoided in the early history of the Survey without a delay 
in the publication of the volumes. It is thought that the 
arrangement in this edition will more fully meet the wants 
of the public, and will render the reports more valuable. 
The first volumes of this edition will comprise the fol- 
lowing: Chemical Analyses, Reports on the Eastern Coal 
Field; Reports on the Western Coal Field; Reports on 
Timbers. Other volumes will be published from time to 
time, preserving the same order of grouping reports. Some 
of the preliminary reports contained in the first edition have 
been omitted, in order that there may be no duplication when 
the final reports are published. I am of the opinion that 
enough preliminary or reconnoissance work has been done 
by the Survey, and the work will be directed with a view of 
securing (so far as the means will permit) complete reports 
on the geology, soils, timbers, etc., of the various regions
