have historic names. They will never be visited by future explorers. But Lee 

 a. one has surveyed the intricate and devious windings which make up the Laby- 

 rinth, together with its associated chambers. Use was made of his work by the- 

 maps which followed. 



The parts of the cavern which are beyond the pass known as El Ghor, includ- 

 ing a considerable portion of explored but unmapped cave, have had several 

 names bestowed on them by the earlier visitors. Of the parts which it will now 

 be impossible to visit, owing to the artificial occlusion of the small passage under 

 Martha's Vineyard, are the following: Byrd's Avenue, Miriam's Avenue, Har- 

 lan's Avenue and Hebe's Spring. The Mystic River itself rivals the famous Echo 

 River, but is less in size. It has probably some connection with Roaring River, 

 a great stream at times, reached from Stephenson's Avenue at the Cascades, but 

 as yet unexplored fully. Several attempts made by the writer to reach its end 

 were defeated by lack of boats, the only means by which the deeper and unfa- 

 miliar places can be passed. 



Lee's map was followed by one prepared from accounts and free-hand sketches' 

 of Stephen Bishop, in 1845, and is found in a little volume called "Mammoth 

 Cave, by a Visitor," and published by Morton & Griswold, of Louisville, Ken- 

 tucky. This map appears to have Lee's map as its basis for the older portion of 

 the cave; the newer portion, which had not then been surveyed, is laid down by 

 Bishop and from his notes. In common with all the published maps of later date- 

 than Lee's, the distances are grossly exaggerated, and the relations of some of the 

 avenues are certainly hypothetical. But this map stands to-day as the best that 

 has been published, and while inaccurate for any scientific purpose is certainly- 

 exact enough for the visitor. It names and shows the points of departure of the 

 side avenues from the larger and better known or more traveled portions^anJ ' 

 gives a sketch of their turnings and ramifications. It is to be constantly remem- 

 bered that none of the maps, except Lee's, have been based upon compass- bear- 

 ings, even, to say nothing of determining their relations by exact method&-. 



No other map appeared until 1875, when Forwood's "The Mammoth Cave of 

 Kentucky," Fourth Edition, appeared from the Lippincott press, of Philadelphia. 

 His map gives only the two traveled routes, called the " long" and the "short" ' 

 routes, and is grossly inaccurate even for these. No dependence can be placed' 

 upon any of the details of this map. It is noticed here simply because it is one 

 of the few which have ever been published. 



Hovey's map, which appeared in his "Celebrated American Caverns " fn~ 

 1882, is the next in order of time. It is probably the best known map of the cave 

 having been reproduced in a number of other publications and been sent abroad
