Introductory and general description. 
In papers of a physiographic nature the Talliilah gorge in 
northeastern Georgia has been incidentally mentioned by dif- 
ferent writers a number of times. 
Nothing on it per se, however, has ever appeared, with 
the exception of an article of a rather general character by 
Dr. W. L. Jones, formerly professor of geology at the Uni- 
versity of Georgia, published in the Atlanta Journal about 
1892. 
An opportunity was afforded the writer during the past 
summer to examine the region in detail, and the following 
paper is offered as a small contribution to the geology of 
Georgia. 
The Tallulah river rises in western North Carolina just 
above the Georgia line, flows in a southeasterlv direction 
through Rabun county in the extreme northeast corner of 
Georgia and, uniting with the Chattooga at the South Caro- 
lina line, forms the Tugaloo, a tributary of the Savannah. 
Its entire course is within the Blue Ridge mountains, the 
easternmost of the southern Appalachians, its flow being down 
tlie southeastern slope and approximately at right angles to 
the axis of the range. 
By reference to the accompanying topographic map (Plate 
X.) it will be seen that all the streams in the region under 
consideration have dissected deep valleys, while the more
