east bank of Muscallonge lake about 4 miles northwest of Oxbow. 

 The material, which closely resembles the Macomb fluorite and 

 occurred in a vein of considerable width in limestone, is now 

 exhausted. Fluorite has also been noted at Vrooman's lake about 

 2 miles east of the above locality. 



Rochester^ Monroe co. Fluorite occurs in the Niagara lime- 

 stone at Pike's quarry. 



Fayetteville, Onondaga co. Fluorite occurs in deep purple 

 cubes associated with gypsum. 



Theresa, Jeffersmi co. Fluorite occurs here associa;ted with 

 calcite and quartz. 



Lochport, Niagara co. Fluorite occurs in the Niagara lime- 

 stone associated with calcite, dolomite, gypsum etc. 



Lowville, Leivis co. Green and nearly transparent crystals of 

 fluorite occur in narrow veins in the limestone associated with 

 calcite, pyrite and galena. 



JoJinshurg^ Warren co. Beautiful crystals of fluorite have been 

 found in this locality. 



2 Phosphate rock. iVpatite, a calcium phosphate of variable 

 composition, is not found in New York State in deposits of 

 sufficient extent to warrant its being mined as a fertilizer. The 

 amorphous nodular phosphates, which in the southern Atlantic 

 States constitute beds of considerable economic importance, are 

 for the most part absent from New York formations. 



Croion Point, Essex co. A fibrous, mammillary variety occurs 

 1 mile south of Hammondsville in this town. Crystallized 

 apatite is also found associated with magnetite in many of the 

 iron mines of Essex and Clinton counties. 



Hammond, St Lawrence co. Large green and light blue crys- 

 tals in calcite. 



Gouverneur, St Lawrence co. About a mile southwest of 

 Gouverneur, crystallized apatite occurs in limestone associated 

 with quartz and wernerite. 



Yrooman's lake, Jefferson co. Apatite occurs here crystallized 

 in the limestone.
