drumlin surface in and south of Ovid village. In the Cayuga 

 Yalley the Newberry waters existed for a time sufficient to 

 produce clear evidences of its presence, but as to Owasco 

 Yalley the evidence is negative. They may have existed there 

 a short time, or the ice dam toward the Canandaigua Yalley 

 may have lifted and drained Lake Newberry before the removal 

 of that which barred the Owasco waters. The earlier Owasco 

 waters (Moravia Lake) were certainly tributary to Lake New- 

 berry by the North Lansing-Ludlowville channel and probably 

 were the easternmost of such tributary waters. 



Lake Newberry certainly included the valleys of Flint Creek, 

 Keuka, Seneca, and Cayuga Lakes, and possibly Owasco for a 

 brief time. In form the lake was an east and west belt of 

 water resting against the ice front, and with four deep bays 

 reaching southward up the valleys above named. Its linear 

 extent was considerable, and its shoreline great, but its total 

 area was not large in proportion. 



Shorelines and Elevations. — The phenomena of the New- 

 berry shorelines have been observed, chiefly as terraces, and 

 wave-built bars on terraces, of landstream deltas, throughout 

 the Keuka and Seneca Yalleys and in the southern part of the 

 Cayuga Yalley. These have all been described in detail in 

 another writing* and it will be sufficient here to briefly men- 

 tion the localities and altitudes. 



In the Seueca Yalley the Newberry shore phenomena have 

 been measured at many localities ; at the head of the valley 

 between Odessa and Montour Falls (Havana), 935 to 940 feet ; 

 at Montour Falls, 950 feet (aneroid). On the west side, at 

 Watkins, 960 feet ; at Himrods, 990 (?) feet (aneroid) ; at 

 Stanley 970 feet. Between Reed's Corners and Ennerdale 

 occur the channels which drained the lake to the Warren level, 

 985 feet to 930 feet (aneroid). On the east side of the valley 

 are good delta ridges at Burdett, 964 feet ; at Hector's Station, 

 976 feet ; at North Hector Station, 984 feet ; at Lodi, 977 feet. 

 At Ovid the level is in the village, but the exact elevation is 

 undetermined. 



In the Cayuga Yalley well-defined beach ridges occur at 

 Trumansburg, 962 feet elevation. No effort has been made to 

 locate the shore phenomena at other points, but they can 

 undoubtedly be found throughout the valley. 



In Keuka Yalley the main delta terraces throughout the 

 valley are 955 to 970 feet elevation, and are attributed to New- 

 berry waters. 



The northward rise of these altitudes is evident and meas- 

 urable, but the matter of beach deformation will not . be 

 discussed in this paper.
