Portland cement in New York during 1900-1 



During the year 1900 two new plants went into operation in this 

 state: that of the Catskill cement co. at Smiths Landing, Greene 

 CO., which began shipping the Catskill brand in July 1900, and 

 the new Portland plant of the Helderberg cement co. at Howe 

 Cave, Schoharie co., which commenced operations late in the year. 

 This last company had produced small quantities of the Helder- 

 berg brand since 1898, but their manufacture of Portland on a 

 large scale dates from the installation of the new plant. Both the 

 corporations named use rotary kilns, and the materials in both 

 localities are limestone and clay. The rebuilt works of the Glens 

 Palls Portland cement co. at Glens Palls, Warren co., com- 

 menced shipping, just about a year having elapsed since their 

 former plant was destroyed by fire. The works of the American 

 cement co. at Jordan, Onondaga co., were shut down throughout 

 1900 owing to new construction at Egypt (Pa.) 



In all, six plants were producers in 1900. 



In the summer of 1901 the Empire Portland cement co. re- 

 modeled its works completely, installing rotary kilns.
