the old Stella inino in 1905 to which it suhscqucntly added other 

 property until its holdings now aggregate ahout 2^,000 acres. At 

 the start Stella no. 2 mine was unwatered and explored, and con- 

 nection was made with the Stella no. i mine situated 800 feet to 

 the south which was found to be on the same vein. A second de- 

 posit known as the Anna vein, situated below and i6oo feet south- 

 east of the Stella, was then developed. 



The Stella veins dip about 28°, while the shaft on the Anna vein 

 has a slope of 45°. The dip is toward the northwest. The ore 

 is hoisted through no. I shaft on the Stella and no. 4 on the Anna 

 vein. In the former mine levels are run at close intervals owing 

 to the flat dip, an^l tlie ore is removed by breast stoping. The 

 Anna vein is worked in levels 75 feet a])art l>y stoping and mill- 

 ing. This vein is paralleled by several deposits within the hang- 

 ing wall which have been intersected by a crosscut from no. 4 shaft. 

 Very little water is encountered in the workings. 



The deposits are described by Air \"ogel as bedded veins con- 

 formable to the gneisses and schists which inclose them. They are 

 apparently related to certain igneous intrusions, though their pre- 

 cise derivation is not known. The ore carries from 15 to 40 per 

 cent sulfur, the highest grade being found in the old Stella mine. 

 The Anna vein averages 24 per cent. 



The mill erected by the St Lawrence Pyrite Co. has a capacity 

 of 500 tons a day. Concentration is effected by Hancock jigs, sup- 

 plemented by Hartz jigs and Overstrom tables. The concentrates 

 carry from 40 to 48 per cent sulfur. They are shipped to acid 

 burners in the East and Middle West. 



SALT 



The salt producers of the State felt the effects of the commercial 

 crisis last year, though in respect to output their showing was 

 relatively better than that made by many other branches of the 

 mineral industry. The depression, however, served to check for 

 the time the upward progress of the local trade. For many years 

 the industry had undergone rapid and almost uninterrupted growth 

 which placed it in a leading position among the salt-producing 

 states of the country. The outjuit of nearly 10,000,000 barrels 

 reported in 1907 w^as about one third of the total recorded for the 

 United States in that year and showed a sixfold increase for the 

 local industry during the last quarter of a century.
