THE JURASSIC FLORA (Continued). 



THE JURASSIC FLORA OF OREGO>f. 



A sufficiently full account of the expedition made in 1899 to the 

 Buck Mountain region of Oregon, as also of previous studies of and col- 

 lections made in that region, was given in the first paper." As stated 

 there, all the specimens that had ever been sent to Washington, including 

 our large collection of that season, and the collections made by Mr. Storrs 

 during previous years, were sent to Professor Fontaine for elaboration, 

 and their study had been begun by him before that paper went to press.

It was completed in the spring of 1901, and Professor Fontaine's report, 

 including descriptions of the species and careful indications relative to 

 the illustrations, was sent on in April. The types have now all been 

 figured, a new process (the WiUiams process) having been employed. It 

 therefore only remained for me to prepare the report for publication. 

 The following paper is essentially the report of Professor Fontaine, only, 

 as in former cases, it has been necessary for me to prepare the synonymy 

 of the previously described species and attend to the systematic arrange- 

 ment. This, therefore, and a few footnotes, to which my initials are 

 attached, are the only parts for which I am responsible. The accom- 

 panying sketch map of the region and section, prepared by Mr. J. S. 

 Diller, will make the geographical and stratigraphical relations clear.
