TEN INDIANA CAVE '8. 165 



The tiresome crawl through Creeping Avenue fin- 

 ished, we stood erect once more in the Junction Room 

 at the head of the Continent and the exploration of 

 the Short Route was at an end. The length of the 

 portions passed through was estimated to be about as 

 follows : 



Fat Man's Misery to Delta Island 1,200 feet. 



Delta Island via Creeping Avenue to Ilovey's Point 2,400 feet. 



Jordan's Waifrvia House of Representatives to the end of 



the Cut Off 2,000 feet. 



Total 5,600 feet or 1.06 miles. 



In going through what is known as the "Long 

 Route" in Wyandotte, we passed from the mouth of 

 the cave to Delta Island over the same way as described 

 above under the " Short Route." At Delta Island we 

 turned to the left and traversed the "Sandy Plain," 

 a passage about 350 feet long, twenty-five feet wide 

 and six to ten feet high ; the floor of which is covered 

 in places to a depth of several feet with sand deposited 

 by the ancient cave river. At the end 

 e ong o ^^ Plain we found ourselves at the 

 foot of the "Hill of Difficulty," which 

 is but a mass of fallen rock, forming, as it were, a 

 foot-hill to the grander " Monument Mountain " which 

 lies beyond. On the left, in climbing this hill, the 

 guide pointed out the exit of Rothrock's Straits, that 

 narrow and deeper passage connecting the Old and 

 New caves. 



Reaching the top of the Hill of Difficulty, we were 

 within the confines of the largest under-ground room 

 yet known to man " Rothrock's Grand Cathedral."
