THE MINING AND QUARRY INDUSTRY I906

tends to erect a calcining plant. The Monarch Plaster Co. began 

 production for the first time in 1906 from its mine situated at 

 Wheatland, Monroe co. Exploratory operations have been under 

 way also near Leroy and Oakfield, Genesee co. 



——- IRON ORE 



The revival of interest in iron ore mining noted in the preceding 

 issue of this report has continued to exert a very favorable influence 

 upon the industry of the State. A larger number of mines have 

 been active during the past year than at any time since the memor- 

 able depression immediately following 1890 which brought about 

 the abandonment of most of the local enterprises. The production, 

 also, has shown a satisfactory gain, and with the increment that 

 will be contributed by the new undertakings when they are under 

 full headway, it should undergo still further expansion. 



Altogether there were 1 1 companies engaged in mining operations. 

 This number includes only those reporting a commercial production 

 of ore. There were several other companies that had properties 

 under exploration or development, and some of them will begin 

 shipment during the current year. 



The accompanying table gives the annual production of iron ore 

 for the period of 1 890-1 906 inclusive. The statistics covering the 

 years previous to 1904 are taken from the volumes of the Mineral 

 Resources published by the United States Geological Survey, while 

 those for 1904 and subsequent years have been collected at this office.
