quartz.” In his Geology of the City of New York, 1909, p. 171, 
Mr. L. P. Gratacap mentions this occurrence of mica schist at St. 
George and considers its probable extension beneath the island. 
Mr. Wm. T. Davis exhibited his collection of the nine species 
of snakes known to inhabit Staten Island within recent years. 
The species are as follows: garter, ribbon, water, DeKay’s, black, 
‘smooth green, ring-necked, milk, and hog-nosed snake. Of these 
the green snake and the hog-nosed appear to have become extinct, 
_ though the latter was not uncommon on the island fifteen or 
twenty years ago. 
The meeting of March 25, 1922, was held in the Public Museum. 
Mr. Charles W. Leng reported the record of Carl Tommerbak 
of Cicindela repanda on the warm afternoon of March 6, in Jones’ 
woods, near Brighton Ave. He mentioned the following dates 
of blossoming for garden flowers: March 12, anemone and crocus; 
March 15, snowdrops. On March 28 Mr. Leng had taken some 
of the children visiting the museum to Richmond, where the but-. 
terfly Vanessa antiopa and the wasp Polistes pallipes were observed 
flying about. This, however, was not an extremely early spring, . 
like that of 1921. 
Mr. Wm. T. Davis showed a number of red maple twigs cut 
off by rabbits and found by him and Mr. Burns on March 5 near 
Ketchum’s mill pond, Richmond. The red maple had been blown 
down by the wind and the branches thus placed within reach of 
the rabbits, who had cut them off diagonally with knifelike sharp- 
ness. 
Mr. R. E. Bell gave an illustrated talk on the Clove Valley and 
vicinity, using lantern slides he had personally made and colored. 
He described the nature of the woods and swamps, and dwelt in. 
some length on the advantages of studying in detail the trees, 
flowers, and birds of a restricted locality. The pictures were 
viewed with much interest by all; the pictures of birds’ nests and 
young being of particular interest. 
The meeting of April 29, 1922, was held in the Public Museum.
