The first centennary of a science in Iowa is upon us. History of the sciences in the commonwealth now goes back beyond the span of our statehood. It transgresses a date when even a name for our state was yet unknown. In Iowa, by many years, claims to first recognition for geology antedate those of every other natural science. Curiously enough this earliest Iowa episode is also the most important geological event for the entire continent during a hundred years. It is even worldwide in some of its aspects. Nor are these early observations alone in their great significance. During the century just passed Iowa has been the field wherein a score or more far-reaching generalizations on geologic themes have had birth. That our state should be thus so intimately associated with the growth of American geology is surely a circumstance of much satisfaction to all Iowan scientists and laymen alike.
