The enactment of such a law is urged as necessary for the relief of certain mining interests upon Lake Superior, which, it is alleged, are in a greatly depressed condition, and can only be sustained by an enhancement of the price of copper.  If this result should follow the passage of the bill, a tax for the exclusive benefit of a single class would be imposed upon the consumers of copper throughout the entire country, not warranted by any need of the Government, and the avails of which would not in any degree find their way into the Treasury of the nation.  If the miners of Lake Superior are in a condition of want, it can not be justly affirmed that the Government should extend charity to them in preference to those of its citizens who in other portions of the country suffer in like manner from destitution.  Least of all should the endeavor to aid them be based upon a method so uncertain and indirect as that contemplated by the bill, and which, moreover, proposes to continue the exercise of its benefaction through an indefinite period of years.  It is, besides, reasonable to hope that positive suffering from want, if it really exists, will prove but temporary in a region where agricultural labor is so much in demand and so well compensated.  A careful examination of the subject appears to show that the present low price of copper, which alone has induced any depression the mining interests of Lake Superior may have recently experienced, is due to causes which it is wholly impolitic, if not impracticable, to contravene by legislation.  These causes are, in the main, an increase in the general supply of copper, owing to the discovery and working of remarkably productive mines and to a coincident restriction in the consumption and use of copper by the substitution of other and cheaper metals for industrial purposes.  It is now sought to resist by artificial means the action of natural laws; to place the people of the United States, in respect to the enjoyment and use of an essential commodity, upon a different basis from other nations, and especially to compensate certain private and sectional interests for the changes and losses which are always incident to industrial progress.

Although providing for an increase of duties, the proposed law does not even come within the range of protection, in the fair acceptation of the term.  It does not look to the fostering of a young and feeble interest with a view to the ultimate attainment of strength and the capacity of self-support.  It appears to assume that the present inability for successful production is inherent and permanent, and is more likely to increase than to be gradually overcome; yet in spite of this it proposes, by the exercise of the lawmaking power, to sustain that interest and to impose it in hopeless perpetuity as a tax upon the competent and beneficent industries of the country.
