BROADHEAD — COAL MEASURES IN MISSOURI. 331 



In Livingston County, on and near Grand Eiver, are 

 about four coal beds ; they are generally from 10" to 14" in 

 thickness, and some of them are much worked. 



Two beds crop out on Locust Creek, in Linn County, but 

 are difficult of access ; they are about a foot in thickness. 

 A IT" bed is worked on Muscle Fork of Chariton, N. of H. 

 k St. Jo. .Railroad. On East Fork of Chariton, and near 

 Hudson, are several good coal beds, relatively V 22", and 

 2V' to 3'. These beds are much worked ; the 22" bed crops 

 out at Carbon and is valuable. 



The same beds crop out on East Fork of Chariton, in 

 Randolph County. The 3' bed above mentioned thickens to 

 5' and 7' in the neighborhood of McGee College ; at Hunts- 

 ville it is 4' and near JRenick 3' ; on Silver Creek it is 4' in 

 thickness ; it also crops out in Adair County, near Nineveh, 

 and on Spring Creek, in Adair and Sullivan. The Flat 

 Creek banks, in Monroe County, include three beds relative- 

 ly 1', 22", and 1'. On Lick Creek, Kails County, two beds 

 are worked — 18" and 24", the latter sometimes 3' thick. In 

 Montgomery, near Wellsville, a 2^' bed is worked. Near 

 Mexico, 1' and 3' beds crop out. In Callaway County, 1' 

 and 3'. Near Columbia, Boone County, is a 3' bed. The 

 Monroe, Kails, Montgomery, Audrain, Boone and northern 

 Callaway coal beds are identical, and include only three 

 beds. 



The best and thickest coal beds occur in the counties of 

 Montgomery, Callaway, Boone, Randolph, Macon, Adair, 

 Howard, Chariton, Carroll, and Lafayette. 



Near St. Charles is a small coal field covering an area of 

 8 or 9 square miles, and containing one bed of coal from 

 15" to 30" in thickness. This is not connected with the 

 larger coal basin of Missouri, and is probably an outlier of 

 the Illinois coal field. 



The regular coal beds are bituminous; the coal breaks 

 with smooth joints perpendicular to the surface, and the 

 surface has generally the character of charcoal. All the 

 coal of Missouri has more or less sulphuret of iron inter- 

 calated with it, and it also often has thin plates of carbonate 

 of lime interpolated in the joints. Fossils are rarely found 

 in immediate juxtaposition with coal, and I only found 

 Brachiopoda in coal at one place in Nodaway County. 



The above is but a brief sketch of the various coal beds, 

 and to do them justice much more would require to be 

 written. 



Palaeontology. — In addition to what has been written 

 above concerning the range of certain fossils, it is but fit to 

 add a few additional facts. Product us tubulospinus is not 

 abundant, and does not range below the middle of Group 

 "H," is more abundant in Group U E," and scarcely ranges
