Among the most remarkable glimpses
nto hidden corners Of nature that re-

he frequent discoveries Of micrO-Or.
Ianisms in unexpected places, where
they produce phenomena heretofore
supposed to arise from other causes.
For instance. DIR. A. Petersen. Of Up

At the latest annual meeting Of the
Geological Society Of America, Prof. I.

Michigan are rich in calcareous mari

Although partly composed Of shells

cement works have lately been con.
structed. others are in contemplation
and Prof. Russell says that Michigan
can easily take a leading place In thai
industry.
