THE CAYUGA FLORA. ix 



the Neguaena valley, south of west Dauby, where a spur of it on the 

 eastern side, forms the interesting knob of Thacher's Pinnacle, and a 

 mile farther east appears in a still more elevated point, Ball Hill, its 

 height unknown but certainly rivalling the Caroline hills. At the 

 eastern base of Ball Hill lies Michigan Hollow Swamp, about 1400 

 feet above tide, while two or three miles south of where the ridge 

 crossed the Neguaena," is Summit Marsh, near the source of Neguaena 

 Creek. The ridge continues eastward to Durfee Hill, west of the 

 White Church valley and reappears on the east side in the bold 

 cliffs of the North and South Pinnacles and then rises to the rounded 

 summits of Bald Hill 1 and Taft Hill, usually known as the Caroline 

 hills. Northeast between the Caroline hills and the Virgil hills lies 

 Dryden Lake. 



The following records from the Survey of N. Y, show some of the 

 elevations along the divide east and northeast of us, the first named 

 being on a northerly somewhat isolated branch : 



No. 113, Dryden sta., on Creamer Hill, central part of Dryden, 18S0 ft. 



" 385, Richford sta., Tioga Co., east of Caroline Hills, 1995 " 



" 402, Virgil sta., Cortland Co., east of Woodwardia Sw., 2133 " 



" 419, Moreheadsta. , " " east of the Round Marshes, 1865" 



" 382, Solon sta., " " northeast of Cortland, 1977 " 



" 107, Niles sta.. Cayuga Co., east of Owasco L. 1621 " 



It will be useful to compare the elevations of some of the marshes, 



ponds, "summits" or R. R. stations iu the valleys near the dividing 



ridge. These are derived chiefly from the R. R. Surveys.

The four higher sphagnum swamps in our basin are the little Spruce 

 Swamp on the Enfield Hills, less than two miles south of the N. Y. 

 S. S. 399, and approaching it in elevation, Michigan Hollow and Fir- 

 Tree Swamps in Danby, and the swamps about Locke Pond. The latter 

 is probably the most elevated pond in our region. The lowest sphag- 

 num swamps are Larch Meadow and Fleming Meadow about 400 

 above the sea. 



The following are the elevations of certain subordinate, but inter- 

 esting points : 



1 The height of Ball Hill, according to Professor H. S. Williams is 

 about 1900 feet. Taft Hill has about the same elevation.
