EAELY HISTORY OF THE PORTLAND CEMENT IN- 

 DUSTRY IN NEW YORK STATE 



BY EDWIN C. ECKEL C.E. 



It seems desirable to explain, at the outset of this brief sketch 

 of the early history of an important industry, the very slight 

 extent to which the nominal author deserves credit for the matter 

 submitted. This prefatory explanation is the more necessary be- 

 cause, for a reason stated farther on, quotation marks and sepa- 

 rate credits have been omitted, except in a few cases; and their 

 absence might lead the reader to the supposition that the sketch 

 was offered as an entirely original contribution to the history 

 of our Portland cement industry. 



In the columns of Engineering news for May 31 and July 26, 

 1900, communications were published from Messrs J. Gardner 

 Sanderson, of Scranton (Pa.) and Edward Duryee, of Colton 

 (Cal.) Their papers, while primarily written for the purpose of 

 clearing up certain doubtful points regarding early use of the 

 rotary kiln in the United States, contained many interesting facts 

 concerning the history of the Portland cement industry in New 

 York state. 



Later, while engaged in the preparation of a paper 1 describing 

 the present condition of Portland cement manufacture in this 

 state, I entered into correspondence with Messrs Sanderson and 

 Duryee regarding their early experiments, intending to make use 

 of their notes in an introduction to the paper mentioned. The 

 material which they placed so generously at my disposal seemed, 

 however, of too detailed and interesting a character to be used in 

 the manner I had purposed, particularly as snch use would have 

 required that the account should be greatly condensed.
