The objection to this theory,which is regarded as more probable than that just discussed, isthe very great irregularity of wind-made features and the factthat these natural mounds of the south-central United States, overan area at least 300 miles wide and 500 miles long, are notablyuniform in size and exactly resemble one another. It wouldseem that in so large an area a wind origin would involve agreater variation in size than has been observed and wouldnecessitate th
