RELICS OF MAN IN THE GLACIAL PERIOD. 251 



the edge of the terrace ; while that at Loveland was 

 found in a coarser deposit, about a quarter of a mile back 

 from the present stream, and thirty feet below the surface. 

 Mastodon-bones also were discovered in close proximity to 

 the implement at Loveland. 



Interest in these investigations was still further in- 

 creased by the report of Mr. Hilborne T. Cresson, of 

 Philadelphia, that in 1886, with my map of the gla- 

 ciated region in hand, he had found an implement of 

 palaeolithic type in undisturbed strata of the glacial ter- 

 race bordering the East Branch of White River, near 

 the glacial boundary at Medora, Jackson County, Ind. 

 The terrace was about fifty feet above the flood-plain of 

 the river. 



Later still, in October, 1889, Mr. W. C. Mills, of JSTew- 

 comerstown, Tuscarawas County, Ohio, found in that town 

 a finely shaped flint implement sixteen feet below the sur- 

 face of the terrace of glacial gravel which lines the margin 

 of the Tuscarawas Valley.* Mr. Mills was not aware of the 

 importance of this discovery until meeting with me some 

 months later, when he described the situation to me, 

 and soon after sent the implement for examination. In 

 company with Judge C. C. Baldwin, President of the 

 Western Reserve Historical Society, and several others, a 

 visit was made to Mr. Mills, and we carefully examined 

 the gravel-pit in which the implement occurred, and col- 

 lected evidence which was abundant to corroborate all 

 his statements. The implement in question is made from 

 a peculiar flint which is found in the Lower Mercer lime- 

 stone, of which there are outcrops a few miles distant, and 

 it resembles in so many ways the typical implements found 

 by Boucher de Perthes, at Abbeville, that, except for the 

 difference in the material from which it is made, it would 

 be impossible to distinguish it from them. The similarity
