THE MAMMOTH CAVE. 17 
1870. The pamphlet of Dr. Binkerd (“The 
Mammoth Cave and its Denizens: A Complete 
Descriptive Guide. By A. D. Binkerd, M.D.” 
Cincinnati: Robert Clarke & Co., Printers, 
1869.—Pamphlet, pp. 96) has appeared since 
the greater part of the present work has been 
in manuscript; and in completing our materials 
for the press we are unable to derive any assist- 
ance from the work of Dr. Binkerd. 
Several newspaper articles, worthy of but 
little attention, have also come under our 
notice. 
At the eleventh hour, since our manuscript 
was placed in the hands of the printers, we 
have succeeded, through the kindness of Mr. 
John R. Proctor, of Maysville, Ky., in procur- 
ing a copy of a work entitled “ Rambles in the 
Mammoth Cave during the Year 1844. By a 
Visitor.” Louisville, Ky.: Morton & Griswold, 
1845. 
This list comprises all the works on the 
subject that we have any knowledge of, with 
the exception of one by Mr. Lee, Civil En- 
gineer, published about the year 1840, said to 
be of some value, but the most diligent search 
on our part has proved unsuccessful in finding a 
single copy.
