On October 23, 1957, a little more than 34 years after Dr, Steagall made the 
first Illinois collection of filmy fern, Dr. M, W. Sanderson, an insect taxonomist 
on the staff of the Illinois Natural History Survey, and I discovered another station 
of this fernin Pope County, at Hayes Creek Canyon, north of Eddyville (Evers 1958). 
On November 19, 1957, William E, Clark, Survey staff photographer, accompanied 
me to the Hayes Creek Canyon locality, fig. 2, locality 12, and photographed the 
stand, fig. 3. We explored the cliffs beyond and discovered an additional stand about 
one-fourth mile from the one found in October, Although I collected specimens from 
the first station in Hayes Creek Canyon, I didnot collect specimens from the second, 
The discovery of the two stations in Hayes Creek Canyon made me doubt my earlier 
conclusion concerning Bethell Hollow, But where was Bethell Hollow ? 
' Neither Bethell Hollow nor Jackson Hollow is shown on a topographic map, 
Names of such places are local, and the exact locations must be obtained from per - 
sons residing in the vicinity. In January, 1958, I wrote to Coy King of Eddyville,

north of Eddyville, Pope County.
