1890-91.] IRON ANB STEEL PRODUCTION IN ONTARIO. 301 



The feature in connection with these deposits, which was pecuHarly 

 gratifying, was their permanency. The result of many years working in 

 this State has enabled the local geological survey to place on record the 

 fact that "their permanent withdrawal and final abandonment has come 

 not so much from the lack of ore or the exhaustion of the veins, but 

 from the heavy expenses attendant on mining operations at a greater 

 depth, etc." 



As an example of this I might quote the fact that the " Hurd Mine " 

 has reached two thousand feet in depth, the " Byron Mine " eleven 

 hundred feet, the " Mount Pleasant Mine " eight hundred feet, the 

 " Dickenson Mine " seven hundred feet, the " Orchard " and " Hibernia 

 Mines " six hundred feet, etc. 



The yield in New Jersey has reached as high as nearly a million 

 tons in one year. In 1889 it produced 415,510 tons while in the same 

 year New York State produced 1,247,537 tons from her Laurentian 

 Series, 



The above mentioned facts are full of significance to us, for the great 

 bug-bear held before our prospectors or investors is that there is no 

 certainty as to the persistency of the magnetite deposits of north-eastern 

 Ontario, as has been shown by many of them playing out in the small 

 development which we have attempted in the past. There is no doubt 

 that many small deposits may prove disappointing in the future, as they 

 have done in the past, but when we fully realize that the continuation of 

 the same series has yielded such results as I have above indicated, we may 

 rest satisfied that under the stimulation of a permanent demand, and of 

 systematic mining development, there can be no question whatever, 

 geologically speaking, about the ultimate permanent supply to be derived 

 from the magnetite deposits of north-eastern Ontario ; that is to say a 

 supply adequate to meet a demand within any reasonable bounds. 



IRON ORE DEPOSITS OF THE SOUTH AND NORTH-WEST SHORES OF 



LAKE SUPERIOR. 



The ores on the north-west shores of the lake occur in geological 

 series running uninterruptedly into the Province of Ontario, and the ores 

 on the south shore of the lake we find in similar, if not entirely identical, 

 geological series to those occuring in Ontario, on the eastern shores of 

 the lake, and where it is not impossible that somewhat similar develop- 

 ments may be made. 



Therefore, for these reasons I have thought a short description of the 

 Iron ranges in the Lake Superior section of the United States would not 

 be without interest to us, as having a direct bearing on the possibilities of
