FLORA OF THE SHASTA FORMATION. 213 



In 1894 Doctor Stanton collected two specimens in the vicinity of 

 Riddles, on the left bank of Cow Creek, which was practically the same 

 locality' as that of most of Mr. Brown's collections, though a few came 

 from the low ridge a mile or more southeast of the town and some distance 

 from the river. These also were sent to Professor Fontaine, who reported 

 on them to Doctor Stanton under date of March 12, 1895, and the iden- 

 tifications were pubhshed soon after." 



The fragmentary character of the material from all these beds, 

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

 it desirable to have a more special search made for vegetable remains, 

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

 California with this object in view. I secured as accurate information 

 respecting the localities as possible and joined Mr. Diller's party at 

 Roseburg, Oreg., on September 6, 1895, after having made the collection 

 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 were 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 Eagle 

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

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

 Horsetown, which 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 by 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 httle. A few fern 

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