PORTLAND-CEMENT INDUSTRY IN NEW JERSEY. 
Three Portland cement plants are at present in operation in New 
rsey, all of them in Warren County, and all using- the Trenton 
nent rock as their principal raw material. In raw materials and 
neral practice these plants agree with the others of the Lehigh 
fcrict, described on page 284, to which reference should be made 
a general discussion of the subject. The following data on the 
tory and production of the three New Jersey plants are taken 
)m a recent report of the New Jersey Geological Survey: 
In 1891 Thomas D. Whitaker commenced the manufacture of Port- 
id cement at Alpha, N. J., establishing what is now the Alpha 
>rtland Cement Company. In 1895 the present operators purchased 
plant, which then had a capacity of from 500 to 700 barrels a day. 
le rock at Alpha produced such an excellent cement that the plant 
is gradually increased, until in 1900 there were 10 kilns, with a 
pacity approximating 2,000 barrels a day. In 1901 a new mill of 
same capacity was erected, the former being known as mill No. 1 
d the latter as mill No. 2. In the summer of 1903, 1 more kilns 
ire added to mill No. 2, making 11 kilns for this plant. This com- 
ny is now manufacturing at Alpha about 5,000 barrels daily. Since 
i issue of the New Jersey Geological Survey's report of the Port- 
id cement industry in 1900, in which the distribution of the cement 
ck was delineated, the company has increased its holdings from 40 
res to 200 acres. The quantity of cement manufactured by this 
mpany since its inception is, in round numbers, 6,000,000 barrels.
