his mind as shown by this letter. The commercial use of the 

 name Cottonwood is so extensive this Survey would be entirely 

 powerless in making a change from Cottonwood to Alma were 

 we to attempt it. Therefore we will continue the use of the 

 name Cottonwood. 



Garrison Formation." — The Garrison formation, so named 

 by Prosser, fills the interval between the Cottonwood and the 

 Wreford limestone and consists of two members, the Fiorina 

 shales and the Neosho member. 



Florin A Shales." — The name Fiorina was given by Pros- 

 ser and Beede, and was taken from the exposure over the Cot- 

 tonwood limestone in the quarries near Fiorina, in the Big 

 Blue valley. 



Neosho Member." — This is so called by Prosser. He says : 

 "This member was originally termed the Neosho formation, 

 from the excellent outcrop in the Neosho valley near Council 

 Grove. The Fiorina shales and the Neosho member are now 

 united to form the Garrison formation, on account of good ex- 

 posures from Garrison south in the Blue valley.
