THE COLLECTION OF MINERALS 
have been both exhaustive and varied. Much of the credit for this 
intelligent activity in collecting and preserving the local minerals be- 
longs to the members of the New York Mineralogical Club, the results 
of whose labors in this field may be seen in the Collection of Manhattan 
Island Minerals, loaned through the courtesy of the New York Minera- 
logical Club and displayed in Case 27. Practically every species of the 
long list recorded from Manhattan Island is included in this series, 
which is not only large and representative, but contains many specimens 
of a quality which renders them noteworthy apart from their unusual 
local interest. Among these latter are especially fine examples of smoky 
quartz, chrysoberyl, calcite, orthoclase, oligoclase, albite, beryl, garnet, 
dumortierite, cyanite, tourmaline, stilbite, chabazite, harmotome, mus- 
covite, titanite, xenotime, monazite, etc.
