The question as to whether the Alma limestone should be 

 substituted for the Cottonwood limestone on account of the earlier 

 name of Cottonwood Creek beds in Texas was submitted to the 

 U. S. Geological Survey Committee on Formation Names and 

 under date of October 29, 1902, Dr. C. Willard Hayes has 

 sent me the following report of the committee: 



This committee approved the name Cottonwood limestone at its meeting 

 March 29, 1902, and at that time considered the priority of Cottonwood 

 Creek beds, Texas. It decided at the time that, although the latter name had 

 priority of usage, it probably was not a clearly-defined formation but merely 

 a bed of unmapable dimensions. Also that inasmuch as Cottonwood Creek 

 beds has not occurred in literature since its first usage in 1893, and whereas 

 Cottonwood [Cottonwood Falls) formation has been used thirteen times since 

 its first usage in 1894, the latter name has acquired a place in literature on 

 the grounds of prescription. The committee therefore decided to adhere to 

 its former decision in favor of Cottonwood limestone." 



In compliance with the above decision the writer withdraws 

 the name Alma limestone and retains Cottonwood limestone as 

 the name of the Kansas formation. ^ e p
