FLOUA OF TlIK SHASTA KOUMATION. 217 



No iimr, however, was lost in liavini; tlu> Ci'iMaccovis ])lants determined, 

 and in Jnly, 1897, all the colKH-tions thus far made from the Shasta beds, 

 inchidino; those tliat had already l^een once studied and report(Hl u])on, 

 wei'e s(>iit to Professoi' Fontaine and h(> made a Ihoi-ou^h examination 

 of it all in the lijjht of the latest collect ions. His final report was com- 

 pleted and ti-ansnutled on Fehruaiy 121, ISOS, and tlie collections wei-e 

 i-elurn(>d to Washin<>;ton. Owing to the n(>cessity of having the .lurassic 

 fioi-as illusti'ated first, I did not send the types of the Shasta fioi'a to the 

 division of illustrations till near the end of May, 1S9!). Th(\v were 

 promptly taken up and completed in July. 



Dui'in.ii; this time a few small collections of HorscMown j)lants had 

 Ix'en made fi'om several localities in Oregon. A single specimen was 

 obtained by Mr. Dillei' from Mr. Claude Rice, who gave the locality as 

 25 miles a little south of east of Buck Mountain. It consisted of a small 

 dicotyledonous leaf on a rock (;ontaining shells of Horsetown age, and 

 was fii'st sent to Doctor Stanton, who turned it over to me on April 25, 

 1898. Three other specimens came into n\y hands through Mr. Diller 

 on May 31, 1898. One of them, in two complementary parts, was col- 

 lected by Mr. Rice, but the precise locality is not stated. The other 

 two, one of which was also in tw'o complementary parts, were collected 

 by Mr. Brown on Cow Creek at Riddles. Another specimen, also collected 

 by Mr. Brown, but from a different locality, viz, on Iron Mountain Creek, 

 half a mile above its junction with Cow Creek, was sent me on February 

 9, 1899. This locality is in the Knoxville beds and is only about 3 miles 

 below Nichols station, where the collection of Jurassic plants was made. 

 I visited it in c o npany with Mr. Brown on September 18, 1899, l)ut we 

 could no find more plant impressions. Aucella is very abundant in the 

 same rocks that yielded the plant. On September 21-23, 1899, I visited 

 several of the localities near Riddles where Mr. Brown had found fossil 

 plants in the shell-bearing shales of the Horsetown beds, but I was 

 mainly unsuccessful in finding plants, which are very rare. 



The interest aroused by bi'inging to light the specim'^n colbcted 

 near Pettyjohn's ranch by I\Tr. Gilbert Thompson in 1882 led to a renewed 

 effort to rediscover the locality. Mr. Thompson furnished Doctor 

 Stanton with full details, including a sketch map of the region, and on 

 September 15 and Ki, 1892, the latter visited the place and made a very 

 careful examination of the beds. He collected specimens showing
