REPORT OP THE STATE PALEONTOLOGIST 1901 533 



shale pebbles were seen embedded in the midst of layers in this 

 portion of the section. No traces of fossils were found. 



This description applies to the rock as exposed at the Ellis 

 dam and just below " Mill C " of the International paper co., 

 1J miles down the river, and also to the lower part of the sec- 

 tion at Kent Falls, 125-A1. 



The upper and fossiliferous portion of the sandstone in this 

 section as seen at Kent Falls, 125-A2 to 13, differs in several 

 important respects from the lower barren portion. The upper 

 part has many layers of thinly bedded, greenish, argillaceous 

 sandstone with shaly partings, on which are fucoids and worm 

 trails. Other layers contain pebbles of shale and dolomite and 

 in these layers are usually found the fossils, which consist of 

 trilobites, brachiopods and gastropods. These upper layers 

 are also wanting in feldspar. The sand grains of which they 

 are made up are markedly rounder, and as a rule the cementa- 

 tion is not so thorough as it is in the lower beds. Heavy beds 

 of compact, even grained, sandstone are less frequent than 

 below. 



The uppermost layer of this section is a heavy bed, 10 feet 

 thick, of white, granular, quartz sandstone, with ripple-marked 

 surface, and cross-bedded section. Its appearance is totally dif- 

 ferent from the heavy beds of the lower portion, its grains 

 being slightly larger, more rounded, and less closely cemented, 

 so that the rock crumbles readily under the blow of a hammer.
