which are exposed and open. The remains were found in a swamp 

 of several acres extent, and the bones were recovered near its out- 

 let. The swamp section showed 2 feet of peat and 3 of marl, the 

 latter resting on a bed of clay. The bones were found in the marl. 

 Some comparative measurements with the Cohoes mastodon are 

 given in the last of the two references cited. 



95 1890. Milton. About this year a very small tooth of a 

 mastodon 20 was found near Milton by Charles Knififen on what is 

 now known as the Bray farm. The tooth is probably still in posses- 

 sion of the finder.

96 1888? Macedon. The remains of the mastodon from the 

 town or village of Macedon are represented by two teeth, which are 

 in the museum of the University of Rochester. They have been 

 identified by Dr O. P. Hay as right and left upper last molars. 

 These teeth were in the musuem, according to a statement of Pro- 

 fessor Fairchild, previous to 1888 but the actual date when they 

 were received and other data relating to the find are lacking. The 

 teeth are of average size, well preserved and very white, apparently 

 from clean sands or gravels. Macedon is the southwestern town- 

 ship of Wayne county 9 miles east of the Perinton locality in Mon- 

 roe county, and 11 miles south of Lake Iroquois beach. Extensive 

 sand and gravel deposits are found in the vicinity of Macedon. They 

 are in the Fairport-Lyons glacial channel, which carried eastward the 

 waters of glacial Lake Dawson and early Lake Iroquois. Not all the 

 delta deposits of ice border drainage have been plotted but the more 

 important of them are shown on Fairchild's 21 glacial maps. The 

 chances that these teeth were found in these glacial gravels are 

 excellent for numerous excavations have been made in them for 

 commercial supplies and also they have been cut through by the 

 New York Central and the West Shore railroads and the Erie (now 

 Barge) canal. The Rochester, Syracuse and Eastern, an electric 

 line, also passes through this glacial channel, but this was con- 

 structed subsequent to the finding of the mastodon teeth. While it 

 can not be proved that the teeth have definite relations to glacial 

 waters on account of the uncertainty as to the exact spot where 

 they were found, yet it is believed, on account of their color, that 

 they did come from these glacial gravels and in point of age these 

 mastodon teeth are among the oldest found in the State.
