RECENT LITERATURE RELATING TO 
STATEN ISLAND. 
Dr.Arthur Hollick read the following 
review: 
The Clays of the United States East of 
of the Mississippi River. Heinrich Ries. 
Professional Paper No. 11, U. S. 
Geol. Survey, 4to, pp. 298, pls. 9, figs. 
11 in text. Washington, D. C., 1903. 
Under the caption ‘‘New York’’ (pp. 
170-179] there are several references to 
the Kreischerville clays, including the 
following analysis of white fire brick 
clay, on p. 174:

On the same page is also given the 
following results of a physical test of a 
similar clay from the same locality: 
Amount of water required to

The number representing themeasure 
of viscosity means a fusing point of 
about 3,326° Far., or 1,830° Cent., 
showing a very refractory clay, 
Mr. A, B. Skinner referred toan il- 
lustrated article entitled ‘‘When Red 
Men battled on Staten Island,’’ by Geo. 
H. Pepper, in the New York Herald of 
March 6th 1904, in which the Indian 
burying ground at Tottenville and the 
work of Mr. Pepper in exploring it 
are described. The illustrations in- 
clude figures of some of the most inter- 
esting of the relics which were unearthed 
there, a view of the sandy field adjoin- 
ing the Cole property, where the ex- 
cavations were made and a picture of 
a part of one of the latter, showing the 
remains of three skeletons in place. 
The work was done under the auspices 
of the American Museum of Natural 
History, where the relics are now pre- 
served. It isa matter for regret that 
this material is not a part of our own 
collection from the same locality. 
SPECIMENS EXHIBITED, 
Mr. Davis exhibited photographs of 
Staten Island trees, taken by Mr. 
Romeyn B, Hough. 
Mr.Skinner exhibited a series of leaf 
shaped arrow points from a number of 
Staten Island localities and a war ar- 
row point found at Horseshoe spring.
