MASTODONS, MAMMOTHS AND OTHER PLEISTOCENE MAMMALS 79 



very clearly the geological time when the remains were embedded, 

 but it does not tell us whether the mammoth was living in New 

 York at that time or whether the remains belonged to an earlier 

 period and were rafted to the drumlin frozen in the ice. The latter 

 view appears the more plausible. 



Warren County 



15 i860. Queensbury. Since 191 1, when the Holden collection 

 was presented to the State, there has been in possession of the 

 Museum a single molar (plate 18) of a mammoth from this county. 

 The tooth had long been in the geological collection of Dr A. W. 

 Holden of Glens Falls. The date of the finding of the tooth has not 

 been definitely determined but it was probably sometime previous to 

 i860. In a letter from the late Dr J. A. Holden written in 1918, 

 he states : " The tooth which during the days of my youth reposed 

 carefully under a glass case in my father's office at Glens Falls, was 

 found on the farm of one John Harris in Upper Queensbury, N. Y., 

 during, as I now remember it although I will not be absolutely cer- 

 tain, an excavation for a' well or cellar." Upper Queensbury is the 

 northern part of Queensbury township, ,and borders Lake George 

 at the lake's southern tip and for a few miles along its eastern shore. 



Unfortunately we do not possess exact information concerning 

 the character of the deposits or the depth at which the tooth was 

 found. If the tooth was found in an excavation for a cellar or a 

 well, it is quite evident that it was not obtained from a peat bog or 

 swampy ground. If it was obtained from a cellar excavation, the 

 depth at which it was found was probably less than 6 feet, but if 

 found in a well excavation, it may have occurred at a much greater 

 depth. The Queensbury mammoth tooth is of special interest on 

 account of being the only proboscidian relic thus far found in 

 northeastern New York. This tooth has been identified by Dr O. P. 

 Hay as E. p r i m i g e n i u s. It has thin enamel but in distance 

 between ridge plates approaches E. boreus Hay = E. j e f f e r- 

 s o n i i Osborn. 



Both sides of the valley in which the Queensbury tooth was 

 found are bordered by rather steep ridges of Precambrian gneisses 

 of the southeastern Adirondacks, although the valley floor is made 

 up of Ordovician rocks. The elevation of the valley does not rise
