delivered the opinion of the Court.
Appellant has contracts with the United States for the construction of levees in Louisiana to control the waters of
*470
the Mississippi River. .It consumes much gasoline in the operation of machinery employed to do the work. It imports its supply from other States in carload lots and places it in a central tank from which distribution is made to other tanks located on its right of way in proximity to the machines. Appellee, an officer of Louisiana, is required to enforce the provisions of its statutes that impose an excise of five cents per gallon in respect of gasoline so imported and used.

The state supreme court has held that the exaction is an excise tax levied upon all gasoline or motor fuel sold, used or consumed in the State
(State
v.
Tri-State Co.,
The appellant seeks reversal on the ground that the contracts are federal means or instrumentalities, that the enactments referred to impose a direct burden upon them
*471
and that the State was without power to impose the tax. And on that basis it seeks to invoke the rule that, consistently with the Federal Constitution, a State may not tax the operations of an instrument employed by the government of the Union to carry its powers into operation. That principle, while not expressly stated in the Constitution, necessarily arises out of our dual government. It has often been given effect.

And reciprocally it safeguards every State against federal tax on its governmental agencies or operations.

Its application does not depend upon the amount of the exaction, the weight of the burden or the extent of the resulting interference with sovereign independence. Where it applies, the principle is an absolute one wholly unaffected by matters or distinctions of degree.
Indian Motocycle Co.
v.
United States,
The power granted by the commerce clause is undoubtedly broad enough to include construction and maintenance of levees in aid of navigation of the Mississippi
*472
River, and to authorize the performance of the work directly by government officers and employees or pursuant to contracts such as those awarded to appellant. The latter method was chosen and the validity of the challenged tax is to be tested on that basis. It is not laid upon the choice of means, the making of the contracts, the contracts themselves, or any transaction to which the federal government is a party or in which it is immediately or directly concerned. Nor is the exaction' laid or dependent upon the amounts, gross or net, received by the contractor. The exaction in respect of its relation to the federal undertaking is wholly unlike those considered in

Affirmed.

The tax is collected from “ dealers ” who, as defined by § 2 of the Act, include “ the person . . . who imports such gasoline or motor fuel from any other State or foreign country for distribution, sale or use in the State of Louisiana.” And on “ all gasoline or motor fuel imported from other States and used by him,'the 'dealer’ . . . shall pay the tax on the amount so imported and used, the same as if it has [sic] been sold for domestic consumption.” Section 14 provides that the tax “ shall not apply to sales to the United States Government or any agency or department thereof.” Act No, 1, extraordinary Session of 1930, imposed an additional tax of one cent a gallon.
