Lead and Zinc. — The only representatives of these metals observed 

 in our district are the two sulphides, galena and blende. These 

 minerals are found associated in a greyish-white crystalline garnet 

 that occurs in lenticular masses in a crystalline limestone on lot 6 of 

 the 1st i-ange of Wakefield. The blende, which is in black, shining 

 cleavable masses, is often so intermingled with the galena as to give, 

 apparently, more prominence to the latter mineral, a feature that must 

 ever be guarded against by intending speculato)s. 



Copper. — The only mineral representing this metal is the yellow 

 sulphide (chalcopyrite) found in specks and small imperfect crystals in 

 some of the veins of the apatite mines. 



Ii-on. — Under this heading we shall, for the sake of convenience, 

 include both the oxides and sulphides of this metal, viz , magnetite, 

 hematite and varieties, limonite, pyrite and pjnhotite. The magnetic 

 oxide, or magnetite, is found in more or less quantity in the above 

 townships. The more workable deposits, however, so far as our present 

 knowledge goes, lie in the township of Hull, where mining operations 

 have been carried on at intervals for the last thirty years. 



The ore coming from these mines is coarse in te.Kture and is often 

 traversed by veins of red hematite, besides occasionally enclosing scales 

 of graphite and mica. Lenticular patches of this ore occur in a dark 

 green pyroxenite on the south half of lot 7, in the 1st range of Wake- 

 field, and also on the north half of the same lot it tills a vein in lime- 

 stone. The outcropping portion is highly crystalline, and owing to the 

 crumbling nature of the walls good crystals often variously modified 

 may be obtained. 



The variety known as specular iron ore occurs at the Haycock 

 location in Templeton and Hull. According to Dr. Harrrington it is 

 in parallel Ijeds in a highly feldspathic gneiss. This ore is often mixed 

 with the magnetic oxide, and often to such an extent as to almost 

 wholly replace the former. A white granular apatite, and a trans- 

 lucent variety of greenish fluor are often associated. The finest crystal 

 of si)ecular iron found in Canada came from these mines. 



The next iron ore noticed (although ])robably not in sutHcient 

 quantity to l)e available for practical purposes) is a vein of limonite 

 of about 1 foot wide, resulting from the alteration of iron pyrites.
