The Butler mine is located on the northern continuation of 

 the Vineyard. It consists of surface workings of only a few feet 

 depth. The body seems too narrow in this direction. 



Kent mine. Thin bands of magnetite appear in the gneiss on 

 the southern slope of Dibble mountain. Three places were found 

 where ore has been taken out in small quantity. The deposits 

 are thin and have been worked only superficially. The production 

 could not have been more than a few hundred tons. 



Breed and Hammond mines. These are situated on top of 

 Breeds hill, i| miles south of Crown Point. Together with a third 

 opening lying on the east shoulder of the hill they form an inter- 

 rupted band of ore that extends across the hill in a northeasterly 

 direction. There is a slight offset in the lines of outcrop of the ore 

 bodies which is suggestive of faulting. The walls in both mines 

 consist of dark, hornblende-biotite gneiss carrying pyrite, but 

 the granite appears in close proximity and seems to have cut it 

 Off on all sides, limiting the former to a narrow belt. 



The Breed mine is opened by an inclined shaft sunk at an angle 

 of 45 . There is a drift 20 feet long at the bottom. The deposit 

 is said to have afforded a breast 8 feet thick. The ore contains 

 biotite and hornblende in considerable quantity, but portions are 

 quite rich. It is highly sulfurous. 



The Hammond mine which lies up the hill and to the east of 

 the Breed is opened by a vertical shaft of no great depth. The 

 outcrop shows about 5 feet of ore r similar to that just described. 



Howe mine. A little exploration has been done on a deposit 

 situated 6 miles northwest of Crown Point. The pit is 5 feet wide 

 and has been excavated on a band of ore which runs northwest 

 up the face of a prominent ridge. A line of magnetic attraction 

 is traceable to the south of the pit, while higher up on the ridge a 

 2 foot band of rich magnetite outcrops with the same strike. 

 The inclosing rock is hornblende gneiss. Pyrite is present in the 

 ore. 



Blye mine. This is a prospect 2 miles north of Crown Point 

 Center on the southern face of Coot hill. The test pit shows a 

 fairly rich magnetite, but the development work is insufficient to 

 afford an estimate as to the size of the deposit. An area of magnetic 

 attraction is reported on the top of the ridge, toward which the 

 ore trends. 



Mt Defiance mine. An interesting occurrence of hematite ore 

 is found just south of Fort Ticonderoga station and west of the 

 Delaware & Hudson Railroad tracks. Mt Defiance is the termina-
