WEST RAGGED REEF TO MINUDIE (6). — LOGAN. 481 



Ft In. 



(In tiiese 15 feet of imderclay there is a beautiful exhi- 

 bition of stigmarige. They are not very abundant, 

 that is to say, in such profuse confusion as usual, but 

 each plant is very distinct. One branch floats along 

 just beneath the surface of the 2 feet bed mentioned, 

 and 24 feet of its length are finely exposed without 

 interruption. The leaves radiate from it distinctly, 

 and individual leaves can be followed down 5 feet, 

 crossing both the hard and the soft parts of the de- 

 posit continuously, and others can be traced 2 feet 

 upwards. Where the branch enters a projecting part 

 of the bed, its measurement is 2 inches verticallv by 

 3 inches horizontally, and where the other extreinity 

 is lost beneath the beach the measurement is about 

 the same, so that I could not come to any conclusion 

 as to the direction in which the branch issues from 

 the stem, if it has one. See fig. 8 [of the original 

 cuts. ] ) 

 Greenish gray or drab sandstone in irregular beds ... 70 

 Greenish gray sandstone, with a vast quantity of drift 

 plants lying in confusion and coated with coal. In 

 one of the beds there appears a bundle of no less 

 10 plants squeezed together side by side, as repre- 

 sented in fig. 8 [of the original cuts.] Each has a 

 core of sandstone surrounded by a good thick coating 

 of crystallized coal. They run through and through 

 a projecting ledge of 10 feet (see fig. 9 [of the origi- 

 nal cuts] ) , and lie rather oblique to the plane of the 

 bed, but conformably with its elementary layers. ... 30 

 Greenish gray sandstone, with some spherical concre- 

 tions of a harder quality, with a rusty exterior .... 50
