As to numbers and distribution, the fossil corkscrews are 

 scattered pretty evenly throughout these beds, and wherever 

 fully exposed, it is plain they flourished in thickly crowded 

 forests of vast extent. In one case six grew almost in con- 

 tact ; in another, ten were counted in a space eight yards 

 long by two yards wide. Along the well-washed banks of a 

 small draw, in a space about two hundred by thirty feet, 

 some forty large specimens were counted and ten dug out.

Barring many other examples, it is plain that if all the 

 fossil corkscrews in a given region could be exposed to view, 

 it would make a forest of ornamented spiral trunks, vying 

 in beauty and magnificence with the fluted columns of the 

 Coal Age. An attempt has been made in Figs. 2, 3, 4, and 5, 

 to show in simple outline the general appearance of the land- 

 scape, the frequency of occurrence of the Devil's corkscrew, 

 likewise the part they play in the landscape at and about 

 Eagle Crag. In the illustrations many corkscrews are neces- 

 sarily concealed behind rocks and other obstructions. 



Viewed from the north, Eagle Crag shows corkscrews and 

 their stumps, all the way from the base, in the extreme fore-
