Saveral mines have beea established on this band with gratifying re- 

 sults. The apatite, which is mostly of the greenisli variety, runs in 

 most cases conformably with the limestone, alihough some small veins 

 were seen intersecting it. The aggregate yield of this band in the town- 

 ship of Hull may be roughly placed at 4,500 tons. 



We also find this mineral an ingredient of tlie orthoclase band 

 running through this town.=hip, and like the latter, characterized in 

 places by a contact wall covered with crystals of pyroxene, apatite,, 

 ])hlogopite, (fcc. I am not aware of any remunerative mines situated on 

 this band. Many atte-^'pts have been made to work the small veins 

 that occur at places, but have generally resulted in failure. 



At Haldane's Mine, in Wakefield, a pit has been sunk 125 feet, 

 on what appears to be a vein, catting the stratification, of a dark -green 

 granular apatite, impregnated with pyrites, also often enclosing epidote, 

 scapolite, pyroxene, &c. The latter mineral is frequently of a caver- 

 nous nature, in which case the cavities are filled with chabazite and a 

 silky fibrous mineral resembling natrolite. 



At Wilson's mine in the same township a fine granular, strongly 

 cohoi'ent, reddish apatite, mixed with a green, cleavable variety filled 

 a vein 12 inches wide in gneiss, which, however, became "nipped" at 

 no considerable depth. 



In following some of the crjstal beds at "Moore's Mines" large 

 cavernous ''bi(gs" were struck, walled with beautiful crystals of 

 pyroxene, phlogopite and apatite. One of these caves was 30 feet 

 long, G feet in width and 8 feet in height, roofed with a pink crystalline 

 limestone, studded with green crystals of apatite standing out in relief 

 on its partly dissolved surfaces. 



The following statistics for the three township? may be summa- 

 rized as follows : — For the township of Hull, up to the present time, 

 between 5,000 and 6,000 tons have been extracted. Wakefield has 

 probably afforded between 8,000 and 9,000 tons, and Templeton between 

 16,000 and 17,000 tons. The total output of all the mines in Canada 

 for this year (1884) is 22,143 tons, extracting 1,790 tons supplied by 

 the Perth and Kingston district, we have 20,353 tons, the jjroduct of 

 the Ottawa county for one year. 



We now come to the anhydrous and hydrated silicates, of which 

 we have about 30 representative minerals.
