only known to luive been mined by the ancient inhabitiints at 

 one locality, and that near Lexington, Ky. A lead vein was 

 here w^orked for one-fourth of a mile by an open cut; but the 

 old works are overgrown by forest and surmounted by trees, 

 some of which have attained the maximum size of the species in 

 that vicinity, and must be not less than five hundred 3^ears old.

MINERALS OF HARLEM AND VICINITY. 



(Illustrated with a suite of specimens.) 



The time rapidly approaches when it will be said that the 

 mineral localities of New York Island are diminishing in num- 

 ber instead of increasing. 



Corlear's Hook (although still appearing on the list in Dana's 

 Mineralogy) long since ceased to be a field of exploration. And 

 other regions of interest, for example, on 23d st., the Kip's Bay 

 Quarries, and adjoining localities on 45th st,, and those on 56th, 

 57th, and 58tli streets, near Sixth avenue, have gradually yielded 

 to the demands of the building interests of the city, sending the 

 student to other localities for investigation. 



East and west of Central Park, the rock masses are in process 

 of removal, so that this district, and the region northward along 

 tiie Harlem Eiver, now claim special attention from the local 

 collector. Already points of considerable interest are open to his 

 researches, <juite equal to many of those above enumerated in a 

 lower portion of the Island. 



Black Tourmalines appear quite plentifully in the neighbor- 

 hood of Harlem. The specimens are often showy, especially 

 when set in albite or oligoclase, but good terminations are very 

 rare. 



In Morningside Park large masses were exposed in blasting 

 operations. These readily disintegrated into black grains, as 

 fine as sand.
