FLORA OF TlIF SHASTA FOKMAl'lON. 213 



III ISO! Doctor Sliiiitoii collectod two simm'Uikmis in tho vicinity of 

 Ivuldlcs, on tiic left l)ank of Cow Crook, which was practi(;ally the same 

 locaUty as that of most of Mr. Brown's coUoctions, th()ii<z;h a few came 

 from tlie low ri(l<!;o a mile oi- more southeast of the town and some distance 

 from the ri\('r. 'I'hcse also wcn'O sent to Professor l'"ontain(>, who repoi'ted 

 on tluMU to Doctor Stanton under date of March 12, LSOo, and tlie idei:- 

 tifications w(>re published soon aftei'." 



Tlie fragmentary character of the material from all these l)eds, 

 wliich rendered most of the determinations more or less doubtful, made 

 il desirable to have a more special search made foi' vegetable remains, 

 and at the urgent request of Mr. Diller I decided to spend some time in 

 ('alifornia with this oljject in view. I secured as accurate information 

 respecting the localities as possible and joined Mr. Diller's })ai1y at 

 Ivoseliurg, Oreg., on September 0, 1895, after having made the coll(>ction 

 of Kootanie plants at Great Falls, Mont., to be described later. It. 

 was arranged that Mr. Storrs should accompany me to the localities 

 in California. I did not stop at Riddles, as the importance of the fossil 

 flora of that region had not yet been emphasized, but proceeded to Ono, 

 Shasta County, Cal., where Mr. Storrs soon joined me, and we spent 

 sixteen days in the general region where fossil plants had been previously 

 obtained. 



Ono was made the base of operations from September 9 to September 

 15, and the principal localities in that vicinity w'ere very carefully exam- 

 ined. Fossil plants were found in Byron Gulch, northwest of Ono and 

 close to the town; on Cottonwood Creek, below the mouth of Eae:le 

 Creek and above that of Hulen Creek ; southeast of Ono ; and in Aldersons 

 Gulch, 2 miles soutlnvest of Ono. We also spent a day in the vicinity of 

 Horsetown, wdiich is 8 miles east-northeast from Ono. 



Two miles northeast of Horsetown, on the road to Centerville, at 

 the southern base of a nearly east-west ridge, the Cretaceous is exposed, 

 overlain ])>^ a mass of tufa. In the fine-grained concretionary rocks 

 that occur among the shales, much as they do in the region around Ono, 

 we made a fairly good collection of plants, mostly conifers. 



The localities near Ono yielded comparatively little. A few fern 

 fragments were found in Byron Gulch. Coal was reported on Cotton-
