126 SLATE DEPOSITS AND INDUSTRY OF UNITED STATES. 
of the Eleventh Census, to the present time, the data as to production have been 
obtained directly from the slate quarries, and are as accurate as can be procured. 
There is no record of production in New York from 1884 to 1890, but the operations 
in this State being closely allied to those of Vermont the output is doubtless included 
in that of Vermont. 
The following tables give the output of slate in the United States from 1879 to 1904, 
by States, showing, as nearly as possible, the number of squares of roofing slate pro- 
duced, their value, and the value of slate used for other purposes, as far as figures are 
obtainable:
