Indiana Academy of Science.—The Spring meeting of the 
Indiana Academy of Science was held at the Wyandotte Cavein Craw- 
ford County, May 15-17. The members and friends spent the greater 
part of two days exploring this great cave. The party made the three 
trips usually open to visitors. The total distance traveled in the cave 
was about twenty miles, and the greatest depth reached about 300 feet. 
This report must be too brief to enter into an elaborate description of 
the long and winding avenues, the grotesque shapes of the many 
beautiful stalactites, stalagmites and pillars, the grottoes, the pillared 
palaces, the large rooms and massive monuments and the numerous 
channels some of the diminutive kind that made it pretty difficult for 
some of the party to pass through. It isa fertile field for the geologist. 
The cave is made in the St. Louis limestone of the Carboniferous. 
Much gypsum was found as well as the various forms of the limestone ; 
also magnesium sulphate and occasional layers of flint. In one part 
yellow ochre is found. The large white masses of Alabaster is espe- 
cially. noticeable in one part. 
A few salamanders were found and several blind crayfish obtained 
from the guides. Many other animals have been found by previous 
investigators. It was a most enthusiastic meeting and also a very 
profitable one.—A. J. BIGNEY, Ass’t. Sec.
