along the creek which flows southeast through the village. This 



section Avas carefully measured by Cleland and as here given 



is practically a reproduction of his, a few lithologic data being 

 added. ^

This section furnishes a thickness of 37 feet, 3 inches of these 

 typical fossiliferous beds. The base of the section is nearly 

 200 feet above the river level, but the underlying beds are ex- 

 posed in very fragmentary fashion. The dip is strong to the 

 west and brings this horizon down to the level of the railroad 

 at the Tribes Hill depot. A short distance east of the depot is 

 a considerable quarry in these beds which was carefully meas- 

 ured by Prosser.^ There are also quarries just west of the depot 

 Avhere the Lowville and overlying limestones are well shown, 

 with the summit of the Tribes Hill limestone beneath. In both 

 those sections there is a thickness of from 15 feet to 20 feet 

 of gray, magnesian limestone and dolomite at the summit of
