the figures above mentioned of the ore output, the traffic done by the 

 railroads is something prodigious. The railroads take the ore for the 

 most part to the Lake-board where it is run out of hopper cars into 

 ore pockets in docks especially built for the purpose, whence again it is 

 run into the vessels, without handling. 



The ore from the Vermillion Range is chiefly shipped from Two 

 Harbors, that from the Gogebic Range from Ashland, that from the 

 Marquette Range from Marquette and Escanaba, and the ore from the 

 Menominee Range also from Escanaba. 



The mode of occurrence of the Iron ore in these ranges may be said in 

 a general way to be somewhat similar. As a rule it is found in a certain 

 bed (or beds) in the Iron bearing formation connected with the occurrence 

 of Jasper, and often with Chloritic or Hydro-mica Schists. The ore 

 occurs in the bed or beds in lens like masses of varying size, and in the 

 ranges alluded to, some immense lenses of solid ore have been opened 

 up. The rocks in the immediate vicinity are generally schists, as above 

 mentioned, and Diorite and Quartzite ridges. 



It might be of interest to mention that the manner in which the 

 Cupriferous and Nickeliferous Pyrrhotite occurs in the vicinity of Sud- 

 bury, also in the Huronian formation, is extremely similar to the manner 

 in which the Iron ore lenses are found as above mentioned, except that 

 there is no Jasper at Sudbury. 



I shall now allude shortly in detail to each of the ranges which I have 

 mentioned. 



MARQUETTE IRON RANGE. 



The Marquette Range in Michigan, comprises a main range chiefly in 

 Marquette County, striking east and west, 8 to 12 miles wide, and 60 

 miles long, the ores occur with Jasper and Chloritic Schists, between 

 Diorite and Quartzite ridges. A second smaller range some 10 miles to 

 the south, comprising the Republic Group, also belongs to the Marquette 

 Range, and in which the ores occur similarly. 



The ores are fine Hematites and Magnetites. As a sample of the 

 composition of the ore from the main range, the following analyses can 

 be given :
