copper pyrites. On lot 9, range A, Orford, and near the junction of the 

 serpentine with a diallagic diorite, six quartz veins occur in the latter 

 rock within a breadth of twenty-five feet. Some of these are ten inches 

 wide, aud they all contain portions of yellow copper ore which is asso- 

 ciated with a greenish serpentine-like material. On lot 22, range 1, 

 Garthby, a large mass of iron and copper pyrites is found subordinate to 

 the stratification of the enclosing rock, which is a calcai-eous serpentine. 

 Iron ores are also found in many places in the Townships associated 

 with serpentine. Large loose blocks of magnetic ore, sometimes half a 

 ton in weight, are found on the second lot of the tenth range of Leeds. 

 They are near a band of serpentine, and probably not far removed from 

 the parent rock. 



An important deposit of magnetite is found on the west side of 

 Nicolet Lake in serpentine. 



Of chromic iron, Dr. Ells reports as follows : 



■' Chromic iron is found in connection with the serpentines at sev- 

 eral places in the area under consideration" (the Eastern Townships). 

 "A deposit on the south side of Lake Nicolet, lot 4, range 2, Ham, 

 was open some years ago, and about ten tons extracted, but the indica- 

 tions were not sufficiently favorable to warrant a continuation of the 

 work. Within the last five years, several openings have been made near 

 Bellmina (lot 24, range 3, Wolfestown), on the crest of the serpentine 

 ridge at this locality. The deposits are apparently of the nature of ir- 

 regular pockets. From the most important of these about twenty tons 

 were extracted from a shaft fifteen feet deep. The vein was five fee^ 

 wide at the surface, but decreased to three feet at the bottom of the 

 shaft. Two hundred yards east of this spot, a second opening wa3 

 made, which produced two to three tons in pieces scattered through the 

 serpentine. Other small deposits were also found, and in all about 25 

 tons were obtained." 



An opening bas been made by Dr. Reid in chromic iron on lot 16, 

 range 4 of Thetford. The mineral occurs there in pockets and very 

 small irregular veins in an asbestos-bearing serpentine. 



In the seigniory of St.. Francis Beauce, there is a bed of granular 

 iron ore, forty.five feet wide, in serpentine. This ore is composed of 

 common magnetic oxyd of iron and ilmenite.
