12 FOSSIL FLOEA OF THE JOHN DAY BASIN, OREGON, [bull. 204. 



Creek, Claruos Ferry, Bridge Creek, Van Horn's ranch, and other 

 places. These plants will be noticed later. 



As already stated, Professor Condon was the first to discover the 

 rich plant beds on Bridge Creek. His collections from this locality, 

 from Currant Creek, and possibly other places within the basin, were 

 prol)ably made during several years, and were ultimately' placed in the 

 hands of the late Dr. J. S. Newberry, of Columbia University, for 

 study. As the partial results of his study Dr. Newberry published, 

 in March, 1883, brief characterizations of fifteen new species of plants.'^ 

 These species, as well as several others, were more full}' described and 

 figured in his Later Extinct Floras of North America,* a posthumous 

 work issued under the editorship of Dr. Arthur Hollick in 1898. The 

 publication of the latter work, containing, as it did the illustrations, 

 made it possible for the first time to be certain of Newberry's species. 

 All, or nearly all, of the material on which Newberry's work was 

 based ultimately became the property of the United States National 

 Museum, where it now is. 



Probably about 1870 Mr. C. D. Voy, a well-known collector of San 

 Francisco, California, made a collecting trip through the basin. He 

 obtained plants from Currant Creek, Bridge Creek, and from a new 

 locality known later as Van Horn's ranch or Belshaw's ranch. These 

 specimens, through the munificence of Mr. D. O. Mills, were pre- 

 sented to the University of California, where they now are. This 

 material was all sul)mitted to Prof, Leo Lesquereux for determina- 

 tion. The exact date on which it came into his hands is uncertain, 

 but it must have been in or before 1878, for a part of the species — 

 certain of those from Van Horn's ranch — were, owing to insufficient 

 labeling, included in his Fossil Plants of the Auriferous (xravel 

 Deposits of the Sierra Nevada,^ published in that year. The remain- 

 der, now known to have come from Currant Creek, Bridge Creek, 

 and Van Horn's ranch, though mainly labeled simply "John Day 

 Valley, Oregon," was described by Lesquereux in his Cretaceous 

 and Tertiary Floras.'' This work bears the date of 1883, and as it 

 contains descriptions and figures of many of the same species that 

 had been submitted to Dr. Newberry, though of course under difi^er- 

 ent names, it becomes a matter of nnich importance to fix more 

 exactly the actual time of issue. In the case of Newberry's paper 

 the actual date is easily fixed })y the date on the final signature 

 as March 21, 1883. From a note in the first page of the Cretaceous 

 and Tertiary Floras it appears that the manuscript was submitted ]\y 

 Professor Lesquereux on September 27, 1882, and was received by the 

 Director of the United States Geological Survey on October 12, 1882.
