on the north bank of Sugar Creek, section 29, township 19 
north, range 4 west, is seen a high bluff of sandstone, which 
been left exposed by excavation. This sandstone forms the roof 
of the crinoid beds and overlies the blue shale in which the cri- 
noids are found. These beds were discovered by the late Prof. 
E. O. Hovey, of Wabash College, in 1836. He first noticed the 
shale, which seemed to be full of crinoid stems and shells; he 
collected a number of these and exhibited them to his classes in 
college, afterwards he called public attention to them. 
In 1842, Horace C. Hovey, son of Prof. E. O. Hovey, began 
to collect these crinoidal fragments, and while he was thus en- 
gaged he found the first crinoid head found at these beds. This 
specimen was an Actimocrinus. 
Mr. R. K. Krout and Mr. Ira Crane visited these banks in the 
year 1851, and collected quite a number of specimens. Mr. Crane 
found, in the ravine, one of the finest specimens of Onychocrinus 
txsculptus that has ever yet been found; this specimen was pic- 
tured in the Scientific American of July 12, 1887. 
Mr. O. W. Corey was the next person to visit the banks. He
