THE MAMMOTH CAVE. 189 



our readers will have already learned, has long 

 since been settled in this country. Dr. P. also 

 alludes to the fact that the Cave has been (and 

 he appears to think still is) used as a sanitarium, 

 — speaking of it as "the sulphurous atmosphere in 

 which medical men kept their patients afflicted 

 with chest affections." Of all affections those of 

 the chest would be the most aggravated by a 

 sulphurous atmosphere; and we are surprised 

 that Dr. P., a medical man, should make such a 

 statement without interposing an interjection of 

 astonishment, and without giving his authority 

 for it. There is no sulphurous atmosphere in 

 any part of the Cave, though one or two sul- 

 phur springs are found. 



In connection with Dr. Poucher's remarks 

 upon the Mammoth Cave there is an illustration 

 of a view of the Dead Sea, which is drawn en- 

 tirely from fancy. There is also another very 

 conspicuous illustration of the River Styx. In 

 the scene a boat is represented, propelled by a 

 negro standing in the prow, with a single oar or 

 paddle, who is shown to be hatless and naked 

 to the loins,* and appears to be making frantic 



* The negro cannot endure as much cold as the white man, 

 and it can scarcely be presumed that he would enjoy any amount 

 of comfort in this condition at the temperature of 59°.
