Plate XIX shows its appearance on Maxwell Run, 0.9 

 mile northeast of Deanville. 



In Skin Creek and Collins Settlement Districts, the Ames 

 Shale has a somewhat different character, being often dark 

 red in color and frequently carrying ferns and other plant fos- 

 sils, the marine life being much less noticeable. 



The following exposure in Collins Settlement District 

 was noted along the public road at the mouth of Sammy 

 Run of Sand Fork, 2.1 miles southwest of Vandalia:

THE HARLEM COAL. 



The Harlem Coal of Newberry 16 , belonging just under the 

 Ames Limestone, is frequently found in the region of its out- 

 crop in Lewis, but it is often absent and is too thin and patchy 

 to have any commercial value. Its best development is in 

 northeastern Hackers Creek District along Jesse Run. At 

 Coal Exposure No. 221 on Map II, 3 miles east of Jane Lew, 

 it is 2' 6" thick, coming just under the fossiliferous Ames 

 Shale at an elevation of 1080' B. At Coal Exposure No. 222 

 on Map II, on a branch of Jesse Run, 3.3 miles east of Jane 

 Lew, the coal is 2' 5" thick, coming just below the Ames, at 

 an elevation of 1110' B. 



In southeastern Skin Creek District, the following se- 

 quence was noted along the public road on Pringle Fork of
