Add to ORKGIn September, 1929, Mr. Howard Miller showed the writer a partly exposed tusk which he thought was a petrified log. It was dug out on October 7th, and found to be 6 feet long, 7¾ inches by 6 inches at the big end, and over 5 inches in diameter at the broken end. It lay in the bed of some tiny glacial or post-glacial stream. Most of it fell to fragments when moved. At a point 1½ miles west the author has found 7 proboscidian teeth and some other bones in the present stream bed
