Chapter V: Front Matter (5)

Whether one's interests are practical, historical, acquisitive, esthetic, philosophical or scientific, the geological features of the Connecticut Valley possess the variety to gratify them all. One must indeed be blind if he cannot find something of interest--a hobby--even a profession in the geological display spread before him in central Massachusetts. Let it not be thought that this little volume tells the whole story. On the contrary, its authors expect to have a difficult time justifying their sins of omission, more particularly because many of the omissions have been conscious and deliberate. But they trust they have left for the reader a wealth of features which he can make his own by right of discovery. For it will not take him very long to penetrate the fourth dimension of geologic time more deeply and intimately than is possible in the pages of a book.
