coal formations of the state. It may have also included a 
description of parts of some of the adjacent counties, in- 
cluded in the second report. An extract from this first re- 
port may be found in the transactions of the Geological 
Society of Pennsylvania, vol. i, pp. 240-243. 
The second report was presented at the regular session 
of the legislature in 1833 and each succeeding report was 
presented at the biennial sessions which followed until the 
tenth and last had been made in 1849. The second report 
embodied the results given in the first report along with 
those obtained during the second. This report was referred 
to a committee which recommended that since it was not 
like the usual legislative document a brief summary pre- 
pared by them be published instead. Since the writer has 
had numerous enquiries for this report* it is presented here,

the members of the legislature as its importance demands, and on 
that account the committee thought they would best subserve the 
interests of the State by giving a brief analysis of the contents 
of the report.

"After having sketched in an interesting preface the labors 
and the enjoyments of the naturalist who investigates the structure 
of the crust of the globe he inhabits, and after having examined 
the first causes which have advanced man to his present state. Dr. 
Troost describes the astonishing progress which the science of 
geology has made during the present generation. He says: 
"Its principal founders and innovators have not yet all left 
the stage of this life. In our new and happy country, its votaries 
are not only vastly increasing, but they find protectors and en- 
couragement from our first and most eminent men. Several of our 
legislatures, convinced of the utility of geological examinations, 
have appointed persons to investigate the structure and mineral
