report of the Pennsylvania survey, and were especially compiled om 
borings and observations made by the directors of coal mines. They ar 
entirely reliable. For Wilkesbarre, there is an upper section coiieiceoide 
coal, which would correspond with No. 5th and 6th coals of 
Kentucky. _ this section was not taken from the same place as 
lower , and as I could not see any of the reported coal beds so as to 
ascertain ghtes paleontology, it is omitted. Some coal beds of unworkable 
thickness are marked in the section of the Pennsylvania report. But they 
are not reported b Mr. Lesley, nor were they marked in a section which 
I obtained of the foreman of the 
Section 13th, at Pittston, is serene by the separation of coal 2d 
and C. 3d, each into two beds, separated by ten feet of shales We have 
seen the same disjunction of these veins at Chinch creek, aoa at Whet- 
stone creek, in Greenup county. 
Section 14th, at Scranton, is also reported in Mr. Lesley’s Manual with

Section 15th, at Carbondale, was obtained from Mr. Ed. Jones, director 
of the mines of Archibald. At Carbondale the hills are too low, and 
contain only the coal 2d. The 3d coal is added from the Archibald’s 
section, which is about the same. In this last es the distance between 
and 2d is 92, and at Carbondale 95 fee

r, Lesley, in his ‘Topographical Geological Report,’ has performed a 
iabior of the greatest poe utility, and one heretofore uite too much 
neglected in our American geology. It is obvious that th 
erosion, forming valleys on the courses of all streams, haye removed cer- 
tain portions of the original spread of coal, While therefore the geologist 
in a general ey A eae colors the whole of a given area as coal-bearing, 
the coal owne to his chagrin that much of the coal which ought to 
be on his ee ale ‘gone to market. The only remedy for such disap- 
sees is found: in accurate topographical maps in which contour 
ines at convenient elevations render certain what portions of the several 
measures remain undisturbed and what are wanting. When to the skill 
of the topographical engineer is added, as in Mr. Lesley’s case, the special 
knowledge of the geologist, the results are truly valuable. 
Kentue ucky has been fortunate in the character of her scientific corps 
employed in this survey, and we earnestly hope, in spite of all ca auses of 
civil disturbance, this work of peace will receive no obstruction either in 
its course of completion or in the publication of its results. 
On a future occasion we shall return to these reports for the purpose, 
among other things, of considering Dr. Peter's results on the agricul Itural
