IRON ORES OP CENTRAL ONTARIO. 11 



oscillate betweou 5*7 and 65. The insoluble rock-matter contaiucd SiO' II. 17, MgO 2.56, 

 CaO 1.43 = 15.16. 



No. 3. Magnetic ore from lot 25, coucessiou 4, township of Snowdou. The ground is 

 practically undeveloped. Metallic iron = 55 per cent. Intermixed rock-matter essentially 

 pyroxeuic 



No. 4. Magnetic ore, very like No. 3, from lot 2'7, concession 4, township of Suowdon. 

 Metallic iron, 50.41 per cent. Ground, practically undeveloped. 



No. 5. Magnetic ore from lot 27, concession 14, township of Gal way. The ground is 

 practically undeveloped. The ore is fine-grained in texture and of very good quality. 

 Metallic iron 62.8*7 per cent. 



No. 6. Magnetic ore, very similar to No. 5, from lot 23, concession 12, township of 

 Galway. Metallic iron 62.60 per cent. Ground undeveloped beyond a few shallow 

 trial pits. 



No. 7. A soft, black, magnetic ore, from lot 5, concession 6, township of Lutterworth, 

 about three miles west of Kinmount village. The deposit, to all appearance a stock-formed 

 mass, has been partially opened, and about 300 tons of good ore have been taken out ; but 

 latterly the working has been discontinued. 



No. 8. A black, crystalline, highly cleaA'able ore, from lot 2*7, concession 13, township 

 of Glamorgan. It holds *70.38 per cent, metal, no trace of titanium, and merely traces of 

 phosphorus and sulphur. The ground is quite undeA'eloped, but there are a few exposures ; 

 and needle attractions show a strong body of ore, ranging N. 65° E., over a length of about 

 400 feet by 40 feet in width. A second, and apparently isolated deposit of similar character, 

 occurs on another part of the same lot. 



No. 9. This ore, from lot 30, concession 13, township of Monmouth, corresponds 

 almost exactly in its cleavable structure and its composition with the ore, No. 8 from Gla- 

 morgan, although the two deposits are several miles apart. The ground is practically 

 undeveloped. Samples taken from a small trial-pit show '70J per cent, iron, with rock- 

 matter under 3 per cent. 



No. 10. A black, partly crystalline, partly granular ore (sp. gr. 4.01) from lot 19, con- 

 cession 1, township of Belmont. The rock-matter is essentially pyroxenic, and hence- 

 practically self-fluxing. Metallic iron 64.26 per cent. Ground undeveloped. 



No. 11. A black, fine-granular ore, from the A'icinity of Apsley village, in the northern 

 part of the township of Burleigh. Metallic iron 63.68 per cent. Intermixed rock-matter 

 essentially pyroxenic. Ground undeveloped. 



No. 12. A very rich, magnetic ore, from lot 25, concession 6, township of Madoc. The 

 sami^le contained some ochreous patches, hence the Fe'O' is slightly in excess. Metallic 

 iron in the dried ore, 69.16 per cent. Intermixed rock matter, 3 to 4 jDer cent. The deposit, 

 apparently a stock-formed mass, shows magnetic attractions over an area of about 200 feet 

 by 40 feet ; but beyond a few trial-pits, from which about 150 tons of ore have been taken, 

 the ground remains undeveloped. 



No. 13. A magnetic ore, mixed with specks of actinolite, from the Seymour Mine, 

 lot 11, concession 5, township of Madoc. The sample contained nearly 1 per cent, pyrites. 

 Metallic iron 60.32 per cent. The intermixed rock-matter (15.54 per cent.) consists of : SiO^ 

 9.02, MgO 4.1*7, CaO 2.13, FeO 0.22. A purer sample of ore from this mine was analysed, 

 some years ago, by Dr. T. Sterry Hunt, with the following results : — Fe'O' 89.220
