because they were midway between the Jackson Hollow and the Hayes Creek Canyon 
stations, Filmy fern was now known from five stations in Pope County. 
In the autumn of 1958 I was able once more to search the cliffs of Pope County 
for the filmy fern, On October 15 I revisited the Steagall site in Jackson Hollow, 
fig. 2, locality 5. The amount of the fern had been so greatly reduced since I first 
saw it in 1951 and especially since my fifth and most recent visit in 1954 when Mr, 
Clark photographed it, fig. 7, that Iasked him to return and photograph the stand 
again. This he did on July 22, 1959, fig. 8. Mr. Clark remarked that the amount 
of the fern had been much reduced since his visit in 1954, On the morning of No- 
vember 13, 1958, I examined the cliffs in Lawrence Hollow, fig. 2, locality 6, which 
is the ravine east of the railroad track and close to Jackson Hollow, south section. 
The search here was futile, In the afternoon I followedthe cliffs which trend south- 
ward from Lawrence Hollow to a point beyond the old Wallace School site, fig. 2, 
locality 7, where in one overhang I found several patches of filmy fern growing lux-

taken, July 22, 1959, the overhang contained several patches of the filmy fern at the rear of the small grottoes 
shown in this view,
