a cave in the Cumberland Valley near Ashland City. This proved 

 to be the jaw of a fossil porpoise from the Cretaceous period. 

 It was found at a point where, up to that time, no Cretaceous re- 

 mains had ever been discovered. 



I have recently obtained from Mr. Joseph Lightman a portion 

 of the teeth of a ]\Iastodon which was found in a cave or sinkhole 

 in the Lightman c[uarry in the suburbs of Nashville. This cave 

 or sinkhole has not as yet been fully explored. It is filled with 

 earth and debris that have washed in from above and can only be 

 explored when more of the surrounding rock has been blasted 

 away, as the quarry is enlarged in the regular course of busi- 

 ness. 



This cave promises to be of great interest for it will likely yield 

 remains of other animals contemporary with the Mastodon and 

 the early cave man.
