George McCready Price, Professor of Geology at a denominational college in Kansas, devotes more than fifty pages of his recent work, “The New Geology” (1923), to an intensely destructive criticism of this dogma of the supremacy of fossil evidence as a means of determining the relative age of strata. To cite Price as an “authority” would, of course, be futile. All orthodox geologists have long since anathematized him, and outlawed him from respectable geological society. Charles Schuchert of Yale refers to him as “a fundamentalist harboring a geological nightmare.” (_Science_, May 30, 1924, p. 487.) Arthur M. Miller of Kentucky University speaks of him as “the man who, while a member of no scientific body and absolutely unknown in scientific circles, has ... had the effrontery to style himself a ‘geologist.’” (_Science_, June 30, 1922, pp. 702, 703.) Miller, however, is just enough to admit that he is well-informed on his subject, and that he possesses the gift of persuasive presentation. “He shows,” says Miller, “a wide familiarity with geological literature, quoting largely from the most eminent authorities in this country and in Europe. Any one reading these writings of Price, which possess a certain charm of literary style, and indicate on the part of the author a gift of popular presentation which makes one regret that it had not been devoted to a more laudable purpose, must constantly marvel at the character of mind of the man who can so go into the literature of the subject and still continue to hold such preposterous opinions.” (_Loc. cit._, p. 702.) In the present instance, however, our interest centers, not on the unimportant question of his official status in geological circles, but exclusively on the objective validity of his argument against the chronometric value of the index fossil. All citations, therefore, from his work will be supported, in the sequel, by collateral testimony from other authors of recognized standing. It is possible, of course, to inject irrelevant issues. Price, for example, follows Sir Henry Howorth in his endeavor to substitute an aqueous catastrophe for the glaciation of the Quaternary Ice Age, and he adduces many interesting facts to justify his preference for a deluge. But this is neither here nor there; for we are not concerned with the merits of his “new catastrophism.” It is his opportune revival in modern form of the forgotten, but extremely effective, objection raised by Huxley and Spencer against the alleged universality of synchronously deposited fossiliferous sediments, that constitutes our sole preoccupation here. It is Price’s merit to have shown that, in the light of recently discovered facts, such as “deceptive conformities” and “overthrusts,” this objection is far graver than it was when first formulated by the authors in question.
