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 1841. 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.
