19. _Fairmount Township, Grant County._—In 1883, A. J. Phinney, M. D., in describing the geology of Grant County (13th Ann. Rep. Geol. Surv. Indiana, p. 143), reported that some years previously the tooth of a mastodon was found in one of the marshes south of the lake in Fairmount Township, number 23 north, range 8 east. In another part of the report it is stated that the lake was in section 14. It covered at the time of writing about 10 acres, but had formerly covered about 30 acres. The drainage is now north into the Mississinawa River; but, before the Wisconsin ice had withdrawn to where the Mississinawa moraine now is, the drainage was toward the south into White River. At some time after the retirement of the ice from this region it became occupied by mastodons, elephants, giant beavers, and doubtless many other species of animals. For 20 see page 91. 21. _Muncie, Delaware County._—A. J. Phinney, in 1882 (11th Ann. Rep. Geol. Surv. Indiana, p. 131), reported that a mastodon tooth was found 4.5 miles west of Muncie, on the farm of Edward McKinley. No details as to depth or kind of soil were given. The tooth is said to have measured 4 by 5.5 inches, with a depth of 7 inches. Unless the roots were present and large it seems not unlikely that the tooth was that of an elephant. Phinney did not say that he saw the tooth. He reported other supposed mastodon remains which had been found in this county, but there is no assurance that they were correctly identified. Whatever proboscideans they were, they lived after the Wisconsin ice had retreated from that region. Mr. M. G. Mock, of Houston, Texas, formerly of Muncie, Indiana, has been interested in making collections of fossils and curiosities. He has kept a note-book of his finds and has illustrated it with sketches. He has a lower right last mastodon molar which was found near Muncie. It is 8.5 inches long, and has 4 crests and 5 roots. He reports having seen a mastodon tooth with 3 crests, which was found June 1887, about 1.75 miles east of Muncie, at the mouth of Hog Creek. Two teeth, of which Mr. Mock still owns one, were found August 8, 1894, 2.5 miles south of Muncie, in a ditch near Buck Creek, on the farm owned by Oliver McConnell. 53. _Royerton, Delaware County._—Mr. M. G. Mock, above referred to, showed the writer a drawing of a mastodon tooth which was found May 24, 1890, near Royerton, 6 miles north of Muncie. With this were two other teeth; one 7 inches long and weighed nearly 4 pounds. These were discovered in excavating tile clay at a depth of about 3.5 feet. 22. _Henry County._—In the collection of Princeton University are two lower true molars, apparently the first of each side. The length of each is 95 mm. They are labeled as having come from Henry County, Indiana, but there is nothing to indicate from what part of the county.
