[PENHALLOW] A REPORT ON FOSSIL PLANTS 289 
they fall within the same general region as 1430—1436, and are pre- 
sumably of the same age, they offer no reliable evidence to this effect. 
Number 1430 of the 1905 collection is by far the most important 
numerically, as well as with respect to the number of recognizable 
species. These specimens not only include previously described species, 
but they also present several new ones, and on the whole, they constitute 
the keynote for the four related localities. 
Numbers 1428, 1430, 1433 and 1436 of the 1905 collections were 
taken from a large area of what has always been regarded as Lower 
Cretaceous, occurring at the Boundary (49th parallel) Line, at a point 
between the Pasayten and Skagit rivers, within an area which is indi- 
cated on the Geological map as Cretaceous. “There seem to ve at 
least 28,000 feet of this series altogether, and it appears to correlate 
with the Shasta-Chico Series.” An important aspect of Nos. 1428 
and 1430 is to be found in their relative ages as well as to whether 
they are really Cretaceous. In this connection Dr. Daly observes that 
“the beds bounding them dip under ammonite-bearing beds of Creta- 
ceous age, but it is possible that they are younger and have been faulted 
down into that attitude.” 
1428 is a locality of exceptional interest, since it has yielded some 
of the most perfectly preserved specimens of the entire collection, and 
it embraces at least one new species of fern which has great value as 
an index of geological age. There are also a number of poorly pre- 
served forms which, by comparison with determinable ones, may be 
correlated with certain doubtful forms observed in the collection of 
1903, with respect to which the provisional conclusions formerly reached 
are now fully confirmed. 
1436 also represents fragments of stems or leaves of a very doubtful 
character, but again, by comparison, it is possible to correlate them with 
recognized species. 
Number 471 of the 1903 collection “ comes from a series of black, 
shaley beds, associated with sandy strata, dipping 35 degrees due east 
en the eastern slope of Sheep Creek valley just southeast of Rossland. 
The fossils came out of bands immediately above the Red Mountain 
Railroad track. The whole series seems to be made up of assorted 
(water-laid) ash beds and tuffaceous deposits. These are overlain by 
coarse agglomerates, which compose much of the great volcanic group 
of rocks surrounding Rossland, and in which the copper-gold ores are 
largely found.” 
Locality 471 is about one hundred and twenty miles east of 1428 
and 1436, being near Rossland, while the latter are on the summit of 
the Cascade Mountains. The specimens from 471 consist entirely of
