[Vol. 2. 



complete a discussion of the fossil floras of the John Day region as 

 possible, but after working on these collections for a short time it 

 was found that so many changes were necessary, and so many new 

 forms must be characterized, and more especially that other allied 

 floras must be considered, that it would take the paper beyond 

 reasonable limits of size. Hence, it was decided, with the consent 

 of Dr. Merriam, to present here a preliminary and tentative list of 

 the species obtained by him, with such geological conclusions as 

 seem warranted at this time, and reserve the final and complete 

 results for publication in the form of a bulletin of the U. S. 

 Geological Survey. Much of the manuscript for this has already 

 been prepared, but before it can be satisfactorily completed it will 

 be necessary to thoroughly revise all of the late Tertiary floras of 

 the Pacific Coast, more especially the Auriferous Gravels and allied 

 formations of California. It is hoped that this may be read}- for 

 publication by the close of the year. 



"The collections from Bridge Creek are of considerable size 

 and contain much interesting material, but the collections from 

 most of the other localities are small and fragmentary, consisting 

 in some instances of single specimens only. Following is an 

 enumeration of species arranged according to localities. All new 

 species are indicated by 'n. sp.,' the names and descriptions being 

 reserved for the final publication."
