Geological Travels in Hungary. 25% 
It being the only* attempt that has yet been made on the 
continent of Europe to make a geological map, it will serve 
to show you the vast confusion and intricacy of the stratifi- 
cation of the old continent; how completely the different 
classes of rocks are mixed and thrown out of their natural 
tinent, and the ease with which the science can be studied 
from the well defined boundaries which nature has given 
to the different classes of rocks, running in the same direc- 
tion, from one end of the continent to the other, having the 
line of separation so distinct between the different rocks in 
the limits of each class as to reduce to a certainty the place 
that each occupies in the natural order. This results from 
the fine opportunities afforded of examining the line of sep- 
aration at every junction, through a distance of twelve to 
fifteen hundred miles, by which means any observer can 
obtain a more accurate knowledge of geology, in one year 
in the United States, than he could ina long life spent in 
travelling in any other part of the globe hitherto examined 
and described. : 
In the year 1815, six years after my geological map of 
the United States was published, in the transactions of the 
ilosophical Society of Philadelphia, Mr. Smith, I believe 
under the patronage of Sir Joseph Banks, published a geo- 
logical map of England, the nomenclature of which is to a 
great extent composed of the local or vulgar names given to 
s by the miners or quarry-men that wrought in them. 
He likewise endeavored, like M. Beudant, to specify each 
individual rock, in colors on the map—a thing very difficult, 
perhaps impossible to be done, with any degree of accuracy. 
Since this, Mr. Greenough has published a geological map 
of England, which I have not seen. eee 
Beudant proves that the anthracite does not belong 
to the primitive class, but seems to think it may belong to 
the secondary. The regularity of our stratification places
