But what an amazing condition of affairs is this. Here are great mountainous masses of rock, very similar in mechanical and mineral make-up to thousands of examples elsewhere. The line of bedding between them "acts exactly like the line of contact of two nearly horizontal formations," and in a natural section cut out by a river the two "appear to succeed one another conformably." And yet we are asked to believe that all this is merely an optical illusion. The rocks could not possibly have been deposited in this way, for the lower ones contain "Benton fossils" (Cretaceous), and the upper ones are Cambrian, and almost the whole geological series and untold millions of years occurred =after= the upper one, and =before= the lower one was formed. Solely on the strength of the infallibility of a theory invented a hundred years ago in a little corner of Western Europe, which "promulgated, as respecting the world, a scheme collected from that province," and assumed that over all the world the rocks must always follow the order there observed, we are here asked to deny the positive evidence of our senses =because= these rocks do not follow this accepted order. I must confess that I cannot see the force of such a method of reasoning. It is carrying the argument several degrees beyond the reasoning of the three little green peas in the little green pod, as narrated in the exquisite fable of Eugene Field. These wise little fellows noticed that their little world was all green, and they themselves green likewise, and they shrewdly concluded from this that the whole universe must also be green. But we are not told of their travelling abroad and persisting in a systematic attempt to explain all subsequently observed facts in terms of their theory. This government Report last quoted from says that in the eastern part of Tennessee the Appalachian Chain "presents an almost identical structure," and refers to a similar state of things in the Highlands of Scotland. Dana, in the last edition of his "Manual" (p. 369), refers to this report, and reproduces some of its plates showing some of the structures referred to; and on another page, in speaking of this similar example in Scotland, says that "a mass of the oldest crystalline rocks, many miles in length from north to south, was thrust at least ten miles westward over younger rocks, part of the latter fossiliferous"; and further declares that "the thrust planes look like planes of bedding, and were long so considered."[28]
