shore of the lake, about five miles north-east of Westport. The ore 

 crops out in the steep and rocky bluff from the water up, nearly to 

 the top of the hill. The openings are 90 to 120 feet above the lake. 

 The ore is very hard and fine-grained, and is reported to contain a 

 considerable percentage of titanium. There are three drifts which 

 follow the ore into the hillside. The ore was run down in chutes to 

 the separating works, which are on the lake, below the mines. The 

 equipment comprises crusher, rolls, magnetic separator, with engines 

 for driving the machinery, and all in fairly good repair, although no 

 work has been done in mining or concentrating in the past six years. 

 The mines are owned by a New York and Albany company. 



In the extreme western part of the town of Westport an iron-ore 

 bed was opened in 1845-1850, on Campbell Hill, and on lots 166 

 and 168 of the Iron Ore tract. The locality was not visited. The ore 

 is reported to be lean and titaniferous. It is four miles from the New 

 York and Canada railway. 



CHESTERFIELD, Essex County. A titaniferous iron ore is 

 reported in this town. It is in the south-west corner and too far 

 from rail communication to prompt much work in further searches 

 or opening. 



MINERVA MINE, Minerva, Essex County.— A vein of mag- 

 netite was opened in this town, north-west of Olmsteadville, by the 

 Burden Iron Co., of Troy, and exploited subsequently in 1881, by 

 the same company, but the small size of the veins and the distance 

 from railroad prevented the further development of the property. 



ADIRONDACK MINES, Newcomb, Essex County.— A remark- 

 able group of magnetic iron-ore outcrops is exposed to view near 

 Lake Sanford on the head waters of the Hudson river. They at- 

 tracted the attention of geologists and iron makers half a century ago, 

 and Dr. Emmons' clear description of these large deposits is so well 

 known that reference to it without quotation is sufficient.* The dis- 

 covery of the ore was in 1826. f The mines were opened in 1832-3, 

 and a charcoal furnace was built, which was in blast until 1846, when 

 a second furnace 56x12 feet was built and was run at short intervals 

 until 1858, since which date it has been out of blast and the mines 

 have been idle.
