GYPSUM DEPOSITS OF NEW YORK 



The production of gypsum and gypsum plasters, so far as statis- 

 tics are available, is shown in the accompanying table. The figures 

 for the years 1889 to 1903 inclusive are taken from the annual 

 volumes of The Mineral Resources, while those subsequent to the 

 latter year are abstracted from the bulletins of the New York State 

 Museum. The total for 1843 is an estimate based on information 

 given in the early reports of Hall and Vanuxem. 



While the production for the years previous to 1889 can not be 

 stated definitely, it is estimated that the aggregate output since the 

 beginning of the industry in the State has been between 4,000,000 

 and 5,000,000 tons. A total approximating the truth may be de- 

 rived by using the known figures for the period 1889-1908 and by

estimating the previous production according to reasonable aver- 

 ages. The estimate for the year 1843 and the reported outputs 

 for several years after 1889 show that until late years there was a 

 fairly steady market for the g>'psum as land plaster material. It 

 is probable that the production did not average over 10,000 tons a 

 year previous to the opening of the Erie canal, for until then the 

 facihties for shipment were limited. From the year of its opening 

 (1826) until 1889 the average was probably about 35,000 tons. For 

 the period 1810-88 the production may be estimated accordingly at
