paper: 
ANALYSES OF SOLID MATTER IN THE 
TOTTENVILLE AND NEW DORP 
WATER SUPPLIES. 
In my paper upon our public water 
supplies, published in our Proceedings 
for Dec. 13th, 1902, I mentioned that it 
would be a matter of considerable in- 
terest to know what were the chemical 
constituents of the solid matter con- 
tained inthe waters. Since then I have 
been furnished with the following two 
analyses, through the kindness of Dr. 
J. A. Deghuee, head chemist of the De- 
partment of Health:

The relatively large amount of lime in 
the Tottenville water is difficult of ex- 
planation in connection with any facts 
now inour posession. There is no lime- 
stone in the vicinity and the amount of 
lime in the Drift and in the underlying 
Cretaceous clays is very small (See 
Proceedings, May 11th, 1901,) so that 
the origin of this constituent is a 
problem which awaits solution. 
In the New Dorp water the relatively 
large amounts of lime and magnesia 
- especially the latter, are to be expected, 
by reason of the close proximity of the 
serpentine rocks, and they point to the 
origin of this supply in the hills to the 
north, although the Drift in which the 
wells aredriven contains more or less 
serpentine as morainial material. 
Mr. Fred. F. Hunt performed a simple 
test to show the solid matter in the New 
Brighton water supply by putting a 
pinch of phosphate of soda into a 
tumbler of the water and causing the 
lime and magnesia to show as a pre- 
cipitate. 
Mr. Nils Bergquist exhibited a small 
leech, which was discharged from a 
faucet supplied from the Crystal 
Water Co. 
Mr. Wm. T. Davis submitted and 
read extracts from a list of additions to 
**StatenIslandNames. YeOldeNames 
and Nick-names,’’ published as Special 
No. 21 of our Proceedings, on March 
14th, 1896. ; 
On motion the following resolution 
was adopted: 
kesolved: that the Association ex- 
press its appreciation of the work of 
Mr. Davis, and that he be re- 
quested to have the same published at 
his discretion, as a special number of 
the Proceedings, under such conditions 
as may be mutually agreed upon be- 
tween the Association and Mr. Davis, 
Mr. Davis also read the following paper, 
illustrated by a specimen: 
NOTES ON THE TIME OF FLOWERING 
OF A WHITK MAPLE. 
The white maple ( Acer saccharinum 
L.), commonly planted along our ave- 
nues and roads, blossoms at this season 
of the year, and for a number of seasons 
past I have noted when the first flowers 
appeared on a tree growing near my 
residence at New Brighton. The flowers 
on this tree are staminate, and the fol- 
lowing table shows the time of their first 
appearance in each year noted:

The position of a tree has much to do 
with its time of flowering, and it will 
often be found that the tree on a sunny 
corner of a street will be in flower,
