REPORT OF THE DIRECTOR, 1922 71 
Plate 1 shows a restoration of this Devonian seed fern. The 
Museum plans to have a restoration of this ancient forest in which 
the actual fossil stumps will be utilized. 
Supplementary Note 
While this paper was in press, new and valuable specimens of 
stumps throwing light upon the nature of the root system of these 
trees, were uncovered in “ Riverside quarry.’ These specimens 
show the underside of the base of the stumps with the impressions 
in the sandstone of roots radiating out in all directions to consider- 
able length. One specimen was removed and is in the possession 
of the Museum. This specimen, with the base of the stump having 
a diameter of about 12 inches, has root impressions measuring up 
to an inch or more across. Specimens were uncovered in which the 
roots were traced for a distance of 6 feet and the tips were not 
reached then. Unfortunately it was not possible to take the large 
specimens from the quarry. However, they show that the root 
systems were considerably larger and more adequate than previously 
supposed, sufficient, at any rate, to support trees of the height to 
which these trees must have attained. The finding of the new speci- 
mens with extensive root systems also answers the criticism that the 
stumps as found were not in situ, because those so far taken out did 
not have the roots attached.
