Book Description
Henry Darwin Rogers is a familiar figure in the history of American geology, especially as the director of the first state geological surveys of New Jersey and Pennsylvania. Although best remembered for the survey work, Rogers considered his theory of mountain elevation to be his most important scientific legacy. Based on studies of the Appalachian Mountains, Rogers's elevation theory was the first American explanation of the dynamics of elevation. As a study of the Pennsylvania survey, this volume offers new insight into the origin and problems associated with early surveys. As a study of Rogers's life and work, it presents a portrait of a man with strong convictions and dedication and examines the development and application of his ideas.

Book Description
In July, 1818, one hundred years ago, the first number of the American Journal of Science and Arts was given to the public. This is the only scientific periodical in this country to maintain an uninterrupted existence since that early date, and this honor is shared with hardly more than half a dozen other independent scientific periodicals in the world at large. Similar publications of learned societies for the same period are also very few in number. It is interesting, on the occasion of this centenary, to glance back at the position of science and scientific literature in the world’s intellectual life in the early part of the nineteenth century, and to consider briefly the marvelous record of combined scientific and industrial progress of the hundred years following—subjects to be handled in detail in the succeeding chapters. It is fitting also that we should recall the man who founded the Journal, the conditions under which he worked, and the difficulties he encountered. Finally, we must review, but more briefly, the subsequent history of what has so often been called after its founder, “Silliman’s Journal.” The nineteenth century, and particularly the hundred years in which we are now interested, must always stand out in the history of the world as the period which has combined the greatest development in all departments of science with the most extraordinary industrial progress. It was not until this century that scientific investigation used to their full extent the twin methods of observation and experiment. In cases too numerous to mention they have given us first, a tentative hypothesis; then, through the testing and correcting of the hypothesis by newly acquired data, an accepted theory has been arrived at; finally, by the same means carried further has been established one of nature’s laws. Early Science.—Looking far back into the past, it seems surprising that science should have had so late a growth, but the wonderful record of man’s genius in the monuments he erected and in architectural remains shows that the working of the human mind found expression first in art and further man also turned to literature. So far as man’s thought was constructive, the early results were systems of philosophy, and explanations of the order of things as seen from within, not as shown by nature herself. We date the real beginning of science with the Greeks, but it was the century that preceded Aristotle that saw the building of the Parthenon and the sculptures of Phidias. Even the great Aristotle himself (384–322 B. C.) though he is sometimes called the “founder of natural history,” was justly accused by Lord Bacon many centuries later of having formed his theories first and then to have forced the facts to agree with them. The bringing together of facts through observation alone began, to be sure, very early, for it was the motion of the sun, moon, and stars and the relation of the earth to them that first excited interest, and, especially in the countries of the East, led to the accumulation of data as to the motion of the planets, of comets and the occurrence of eclipses. But there was no coördination of these facts and they were so involved in man’s superstition as to be of little value. In passing, however, it is worthy of mention that the Chinese astronomical data accumulated more than two thousand years before the Christian era have in trained hands yielded results of no small significance.
