OF STATEN ISLAND. 
Vou. VIII. No. 6. 
May 11th, rgor. 
An informal meeting of the Association 
was held at the Staten Island Academy. 
The following review was read by the 
Secretary : 
RECENT LITERATURE RELATING TO STATEN 
ISLAND. 
Clays of New York: Their Properties and 
Uses —Heinrich Ries, Bull N. Y. State 
Museum, No 35, Vol. 7 (June 1900), 8 vo., 
cloth, pp. 489-944, pls. I-140 and map. 
This is in general a complete scientific and 
technical, up to date dissertation, upon the 
clays of New York State, giving the geographic 
and geologic distribution of all the clay work- 
ings within the limits of the State; manner of 
quarrying ; methods employed in manufactur- 
ing the various articles; analyses of raw ma- 
' terial; tests of finished products, ete 
In it Staten Island receives a large share of 
attention, both in the text and in the illustra- 
tions. Plate 1 (Frontispiece) and Pl. 81 
represent terra cotta vases made at the factory 
of B, Kreischer’s Sons, Kreischerville, and PI. 
78 is a view of Barnard College, New York, 
showing the terra cotta trimmings from the 
same factory.—Views of the interior of the 
factory are given on Plates 79, 80, 106, 107, 
108, tog and 111, while the exterior, on the 
water front, is shown on Pl. 110. 
Two of the clay pits are represented on 
Plates 17 and 105 and figures of a number of 
our Cretaceous fossil leaves on Plates 18 and 
19, as follows: 
Pl. 18. Rhamnus Rossmassleri Ung. Totten- 
ville. 
Pterospermites modestus Lesq. Totten- 
ville. 
~Laurus plutonia Heer. Tottenville. 
Proteoides daphnogenoides Heer. Tot- 
tenville. 
Tricalycites papyraceus Newb. Totten- 
ville. 
Eucalyptus Getnitzi Weer. Totten- 
viile 
Myrsine elongata Newb. Arrochar. 
Myrica longa Newb. Arrochar. 
Thinnfeldia Lesquereuxiana Weer. 
Princes Bay. 
Pl. 19. Proteoides daphnogenoides Weer. Tot- 
tenville. 
Laurus plutonia Weer. Tottenville. 
Liricdendropsis simplex Newb. Totten- 
ville. 
Liriodendropsis simplex Newb. Princes 
Bay. 
Moriconia cyclotoxon Deb 
Princes Bay. 
Populus apiculata Newb. (?) Arrochar. 
These are of particular interest to us, as 
the specimens figured are all in our muse- 
um; they were collected and identified by 
members of our Association and were previ- 
ously described in our Proceedings or in the 
Transactions or Annals of the New York 
Academy of Sciences.
