PRESENT CONDITION. 
Ten Portland cement plants are now in operation in New York State. 
Diie employs Trenton limestone and clay, four use Helderberg lime- 
Itones with clay or shale, one usesTully limestone and shale, and four 
Imploy marl and clay. Another plant, using" marl and clay, has been 
pie for some 3 T ears, but is described below. 
I Alsen's American Portland Cement Works are located at West 
Camp, or Alsen station, Greene County, near the plant of the Catskill 
Cement Company. The materials used are the Becraft limestone, of 
lie lower Helderberg, and clays of Quaternar}^ age. As usual with 
pese clays along the Hudson River considerable trouble has been 
Incountered in using them for cement material. Excellent shales, 
lowever, occur in the immediate vicinity of the plant, and these can 
|e used with the limestone. The latter is of the usual composition of 
pe Becraft, high in lime carbonate (about 95 per cent) and low both 
li clayey matter and magnesium carbonate. 
The plant of the American Cement Company, located 2 miles east of 
Jordan, Onondaga County, was erected in 1892. The works were 
perated without interruption until 1900, when they were shut down, 
wing to new construction by the company at Egypt, Pa. 
I The materials used were marl and clay, both obtained from a marsh 
[ear the works, another bed of marl being owned Jry the company 
learer to Jordan station. The marl is white, and the bed varies in 
hickness from 8 to 15 feet. It is overlain by a thin bed of muck and 
inderlain by a blue clay. The muck being stripped, the marl and 
flay were dug and transported to the works by a wire ropeway. The 
llay was dried and ground separate^, after which it was mixed with 
(he marl in pug mills. The resulting slurry was spread out on a dic- 
ing floor and cut into bricks. These bricks were then loaded on plat- 
orm cars, dried in tunnels heated by coal fires, and fed to the kilns, 
twelve kilns, of the dome type, were in use, coke being used as fuel. 
! The clinker was reduced, first in Gates and Mosser crushers, and 
fnally in Griffin mills. The cement was marketed as the Giant 
Jordan) brand. The following analyses of the raw materials and fin- 
shed product were furnished by the company:
