Excerpt from The Zonal-Belt Hypothesis: A New Explanation of the Cause of the Ice Ages The nature of the evidence demonstrates that these belts were potent factors in producing' the climatic changes which marked the various geologic periods. They were the cause of the Ice ages. Primitive man saw the last remnants of these strange sights in the sky, and the echo of his thought in the form of mythology has sounded down through the lapse of the centuries. Facts cannot be ignored. Agassiz demonstrated that the till and boulder deposits scattered over the mantle rock of northern Europe and North America were the product of glacier action, but though the fact of the existence of great continental ice - sheets was established, the cause has remained up to the present date a scientific mystery. Now, in presenting the belted-canopy or zonal-ring hypothesis the cause or causes which brought them into exist ence is of secondary importance. The all-important matter is to establish their actuality. Nevertheless, in order to present the argument in a consecutive form, the author under takes in the opening chapters to show how the belts could have been brought into existence. This portion of the work, however, may be considered as merely tentative, and if he has failed in this particular, it in nowise compromises the main issue.
