WARD.] JURASSIC FLORA OF OREGON. _ 371 
somewhat careful preliminary study of them before sending them to 
Professor Fontaine for final determination. In my letter to him dated 
January 8, 1897, transmitting them, I said: 
There is a Teeniopteris that seems to be T. orovillensis or something very near that, 
and it is the commonest plant in the collection. The other things are different in 
the main from the Oroville plants, but I believe they are as old. 
I wish you could look over this collection pretty soon and’let me krow whether 
you think it is Jurassic and whether you think it important, because Mr. Storrs made 
it all in one day in a great hurry, and I understand there is plenty more. 
Professor Fontaine made the following prompt preliminary report 
on this collection: 
I have examined the Douglas County fossils and have no doubt that this is essen- 
tially the same flora as that of Oroville. The material is coarse and does not preserve 
the plants very well, but so far as I can judge from the impressions, there is a remark- 
ably large number of identical forms here and at Oroville. Of course I would not 
like to give a final decision on forms from such imperfect material, but it seems to 
me that Teeniopteris orovillensis occurs here and perhaps a larger form. Ctenophyllum 
angustifolium seems to be common. Several of the small ferns seem identical with 
Oroville forms. The Oroville Sagenopteris almost certainly occurs here, also an 
Angiopteridium like that of Oroville. Some fragments look much like the Cteno- 
phylla of Oroville with coarse nerves. Pterophyllum rajmahalense is probably found 
here. 
The Oroville plants ought to be figured for comparison before these are worked up. 
I certainly think that a larger collection ought to be made before a final determina- 
tion can be formed. I should think that the strata would yield some shale bands 
which would preserve the fossils better. However, for a ‘‘haphazard”’ collection 
in one day, this is a remarkable yield. 
Professor Diller was informed of these results and the importance 
of increasing the amount of material and of making a more careful 
study of the stratigraphical position of these beds and their relation 
to the bed near the summit of Buck Mountain yielding the specimens 
collected by Mr. Todd. On June 30, 1897, Mr. Storrs returned to the 
locality and made a much larger collection, which was at once trans- 
mitted to me, through the Director of the Survey. In his letter to 
the Director, dated July 4, 1897, Professor Diller says: 
By this mail I have the honor to transmit seven packages of specimens of fossil 
plants from the locality on Olalla Creek, at which a number of similar specimens were 
collected last year by Mr. Storrs. I respectfully request that they be referred to 
Professor Ward for study and report. For his information I desire to say that the 
plant beds appear to belong to the series of strata containing Aucella. Specimens of 
the Aucella were collected in shales which appear to underlie the leaf beds and will 
be sent also by this mail forexamination. The Aucelle are from Buck Peak, at the 
base of which the leaves occur, and do not appear to have the characteristics of the 
Jurassic Aucellz, but rather those of the Knoxville beds. 
As a consequence of all this a lively correspondence took place dur- 
ing the summer of 1897, participated in by Professors Diller and Fon- 
taine, Mr. Storrs, and myself, as to the probable age of the plant- 
bearing beds, and in the course of which Professer Diller succeeded in 
locating Mr. Aurelius Todd at Dunedin, Florida, and obtaining from
