also hoisted some ore from the upper workings reached by the 

 incHne. The Welch shaft farther north contributed a small output. 



Cheever mine. The recently revived operations at this mine 

 near Port Henry continued to afford a good output during the past 

 year. The southern end of the old workings have thus far received 

 most attention. Though no extensive bodies of rich ore have been 

 found, a large quantity of material of concentrating grade has been 

 developed, sufficient to assure a steady production for some time to 

 come. The shipments are all in the form of concentrates, made in 

 a local mill. 



Some prospecting has been under way during the year on the 

 northern continuation of the Cheever ore belt. The results of the 

 work which was carried on by a Buffalo company have not been 

 given to the public. 



Lyon Mountain. The mines at Lyon Mountain were operated as 

 usual for the supply of the Standish furnace. 



Benson Mines. No production of ore was made by these mines 

 last year. The results obtained with the old mill proved so unsatis- 

 factory, that work was suspended and preparations started toward 

 its replacement by a new structure. This is now in course of erec- 

 tion. The mill which is planned for two units will be first equipped 

 for a single unit with a capacity of looo tons crude ore a day. The 

 scheme of separation involves the use of dry magnetic belt and 

 drum machines following the general plan adopted in the other Adi- 

 rondack mills. A storage capacity of 10,000 tons of dried ore will 

 be provided so as to insure continuous work during the winter season 

 which is rather severe in that region. Power for the mines and 

 mill is to be supplied from an independent hydro-electric station. 



MINERAL PAINT 



Under this title are included the natural mineral colors which 

 require nothing more than grinding or washing in their preparation 

 for the market. The raw materials found in the State that have been 

 used for the purposes are iron ore, ocher, shale and slate. New 

 York is also one of the leading producers of artificial pigments, 

 specially those made from lead, but as the materials are derived 

 from outside sources no account of them is taken in this place. 



The Clinton hematite affords an excellent base for the manufac- 

 ture of metallic paint and mortar color. The beds with a relatively 

 high iron content are employed, as they possess the softness and
