deposits at Kreischerville and Green Ridge 
are deseribed on pp 607-611, including the 
following fact not before recorded locally: 
*“T sponge] Spicules have been observed 
in the fire clay at Kreischerville * * * In 
the Kaolin were discovered a number of dia- 
toms, which Dr. Ward inferms me are either 
Coconeis placentula Ehr., or C. pediculis Ehr. 
Their occurrence is also of great interest, as 
these Kaolins are known to be middle Cre- 
taceous beyond doubt.” 
The following sections are given on p. 608: 
‘* Boring at Kreischer’s factory : 
Sand and soil 30 ft. 
Blue clay go ft. 
White sand Zatti 
Sand and clay alternating 78 ft. 
Total thickness 200 ft.” 
Also : 
‘‘ The following record of a well bored fo, 
Bachmann’s brewery at Annadale, S. I. * * * 
At a depth of 200 feet a bed of yellow gravel 
containing shells was struck. The gravel 
was 36 feet in thickness and beneath it was 
a bed of clay ro feet thick. The latter was 
of a white and blue color and was said to 
resemble a fine pottery clay.” 
As this record appeared to be erroneous, 
either in regard to the locality or the name of 
the brewery, I endeavored to obtain some 
more definite information from the author, but 
as he had merely received it second-hand the 
result of- my effort was not satisfactory. 
Bachmann’s brewery is at Clifton, 
Onp 610 is the following analysis of so- 
called ‘* Kaolin” from Campell’s pit : 
** Silicic acid and sand 
92.70 
Al2 03 and Fe 20 3 5.70 
lal A® -70 
K20 735 
On pp 742-43, under the eee of 
building brick, are mentioned Mc’Cabe’s yard 
at Green Ridge ; Wood & Keenan’s on Arthur 
Kill, and the Anderson pressed brick factory 
at Kreischerville. 
On pp. 759 - 60 is mentioned the clay quar- 
ried near Rossville (‘Roseville” in the Report) 
by T. Ryan, with tests for shrinkage, vitrifi- 
cation, tensile strength, etc. The composition 
is givenas : 
Sune 57.00 
Alumina 29.20 
Ferric oxid 4.80 
Lime -65 
Magnesia 31 
Alkalies I $0 
Water 6.10” 
On pp. 763 -64, under descriptions of the 
terra cotta industry, Kreischer’s factory is 
given a prominent place and on pp. 788 - 90, 
under the subject of fire clays, is a more de- 
tailed description of the Kreischerville beds, 
which are stated to be the only ones at the 
present time, in New York State, from which 
fire clays are mined, — Shrinkage, tensile 
strength and refractoriness are discussed and 
the following analysis given of clay from a pit 
opened in 1897 near Killmeyer’s hotel: 
** Silica 47 40 
Alumina 39.01 
Ferric oxid .15 
Lime trace 
Magnesia S 
Alkalis i 
Water 14.10 
100.66” 
This was found to be a white and highly 
refractory clay. 
In addition to the above, mechanical analy- 
ses are given, showing the amounts of clay, 
silt and sand in several samples of clay from 
the same locality. 
On p. 872, in a table of analyses of fire 
clays, No. 29, from Kreischerville, is given as 
follows : 
Silica 64 28 
Alumina 24.76 
Ferric oxid .83 
Lime T3 
Magnesia trace 
Alkalis 2.35
