When the Nephites came from Jerusalem, they gave us no account of finding these huge animals upon the continent, although they found an abundance of the other animals above referred to. We may, therefore, reasonable conclude that the last three named perished with the Jaredite nation. But it is remarkably strange that the bones of these animals should resist decomposition for the immense period of three or four thousand years. The mind also naturally inquires, How came the bones of this Curelom or Cumom to be 83 feet below the surface of the earth? Were its deep coverings the result of the 300 years' accumulations of the debris or washings of the Mohawk river? Or was the skeleton suddenly engulphed during the tremendous convulsions of the New World, at the time of the crucifixion? (See Book of Mormon, p. 450.) Professor Agassiz, by an inspection of the locality, will no doubt be able to throw much light upon these questions. The Omerites who inhabited all that region of country, nearly four thousand years ago, would have been filled with the wildest astonishment had they foreseen, the intense curiosity and peculiar care, which the New Yorkers are now bestowing upon the bones of one of their domestic animals.
