44 Editorial Comment. 
The dissatisfaction of this pubHc with the position of biology 
and geology in the schools is plainly expressed in such move- 
ments as that of the "Agassiz Association" with its seven thou- 
sand members, and "Chatauqua Scientific Circle" with its thirty 
or forty thousand readers and students. We feel sure that public 
opinion will ultimately compel our moss-grown, conservative 
educators to admit geology in some of its aspects into the sec- 
ondary, and even the primary schools, and will revolutionize 
the collegiate control which persists in consigning geology to 
an insignificant position. I'his result, however will be reached 
through instrumentalities; and we have hoped such an undis- 
guised statement as here made may contribute something to 
the much needed reform. 
We beg to disclaim all hostility to the true interests of any 
department of learning; for there is no learning in which we do 
not feel deep concern. We desire only to rebuke the assumption 
of some forms of traditional learning, and protest against a policy 
in university control which sanctions their arrogance and helps 
them to rob certain other departments of their equitable stand- 
ing and material support. 
IRVING AND CHAMBERLIN ON THE LAKE SUPERIOR 
SANDSTONES. 
That perennial source of discussion, the age of the lake 
Superior sandstones and trap-rocks, has recently been revived by 
the contributions of Profs. Chamberlin and Irving to the litera- 
ture of the United States geological survey. In bulletin No. 23' 
they have given an elaborate description and discussion of the 
geology of points that are considered by them as crucial, situated 
on Keweenaw point, Michigan. They describe the contact of 
the trap and sandstone formation with the "eastern sandstones" 
at Bete Grise bay, at Wall ravine, at St. Louis ravine, at 
Douglass Houghton ravine, at the Torch lake quarry, at Hun- 
garian ravine, and at other points. They also review and dis- 
cuss, sometimes with ideal representations of the stratigraphic 
' Observations on the junction between the eastern sandstone and 
the Keweenaw series, on Keweenaw point, lake Superior. By R- D. 
Irving and T. C. Chamberlin.
