 rector in January 1902, when the remainder of the bulletin was 

 in page proof. Part of its incompleteness is due to the necessity

 cussed in somewhat greater detail in the paper above noted, to 

 which the reader is referred : but advantage has been taken of the 

 present publication to bring the descriptions up to date. As it 

 now stands the paper is therefore a summary of the condition of 

 the New York Portland cement industry in January 1902.
