 All of them find representatives in the Norwegian group around 

 Trondhjem, and in the Dovre^eld, 



This resemblance is still further traced in the metalliferous 

 deposits of the two regions. In the Eastern Townships of Can- 

 ada, copper sometimes occurs in the native state, in clay slate, but 

 much more frequently in the form of yellow and variegated sul- 

 phurets, or of copper glance, disseminated in micaceous or chloritic 

 slates, or in limestone. These deposits are of the nature of fahl- 

 bands. Those of Sutton and Ascott, especially the latter, have a. 

 strong resemblance to that of Roraas. The copper ores of this re- 

 gion are generally subordinate to the stratification. The short, 

 and irregular veins of quartz and bitter-spar, which traverse these 

 copper-bearing strata, sometimes however carry rich ores of cop- 

 per, occasionally with gold. 



Iron schists, which consist of scaly peroxyd of iron, intermin- 

 gled with various proportions of quartz and chlorite, constitute 

 important beds of iron ore in some parts of this series, as in the 

 townships of Brome and Sutton, where they were formerly wrought 

 to a small extent. These schists resemble the itabirite of Brazil. 



Chromic iron accompanies the serpentine in Canada, as in Nor- 

 way. The deposits of this ore occurring in the townships of 

 South Ham, Bolton, and Melbourne, greatly exceed those of Nor- 

 way in richness and extent. The deposit in the first named 

 township has been worked, producing an ore containing forty- 

 three per cent of chromic oxide. 



As far as regards the developement of the mineral resources of 

 the group, Norway is in advance of Canada. Not only has the 

 mining of copper and chrome ores been long established, but the 

 manufacture of the valuable products obtainable from these, has 

 been long and profitably pursued. The mines of Roraas are be- 

 ginning to sufi"er from the scarcity of fuel at the great height, (2080 

 feet above the sea,) and the chrome mining and manufacturing 

 has had to contend with expensive cartage, and often with high 

 prices for potash, which is to a great extent imported from Russia. 

 In Canada, around the mines of the Eastern Townships, the settler 

 destroys acres of timber, the softer sorts of which he might 

 burn to charcoal ; and manufactures tons of potash, which the 

 chrome miner might buy, and use to manufacture his ore into 

 chromate of potash, at a rate alike profitable to producer and con- 

 sumer. I am not aware of any district where greater advantages
