delivered the opinion of the Court.
Petitioner brought suit in the District Court for Western Texas to recover federal income taxes alleged to have been illegally exacted for its fiscal years 1925 to 1928, inclusive. It set up that in those years it received income derived from the sale of oil and gas produced under leases to it by the State of Texas; that these leases were instrumentalities of the State for the development of its public domain; and that petitioner’s income derived from them was constitutionally immune from the tax as one imposed by the Federal Government on an instrumentality of the State. The District Court .gave judgment for petitioner, 38 F. (2d) 680, which the Circuit Court of Appeals for the Fifth Circuit reversed, holding that the immunity, if any, had been waived by the State by § 27 of Chapter 83, Laws of 1917, which provided that rights acquired under leases, including the present ones, were to be “ subject to taxation as is othér property.” 41 F. (2d) 483. This Court granted certiorari,
*281 Petitioner’s leases relate to parts of the public domain of the State, set apart by the legislature for the benefit of the state university, under a mandate of the State Constitution of 1876, Art. 7, §§ 10-15, inclusive. See Texas Laws, 1917, c. 83. In terms they “ grant and lease ” for a period of ten years, with renewal privileges, the right to enter on designated lands for the purpose of “ drilling and operating ” for petroleum and gas, and to erect and maintain all necessary structures for the production, transportation, and storage of petroleum and gas. The lessee or “ owner of the rights . . . conveyed ” is required to pay the State the value of one-eighth of the petroleum produced and of one-tenth of the gas sold. The challenged tax is measured by the net profits derived by petitioner from the sale of oil and gas produced, after making allowed deductions from gross receipts, including the royalties paid to the State.
Section 12 of Article 7 of the State Constitution, as interpreted by the highest court of the State,
“
requires the Legislature to dispose of the University lands by
sale
only.”

v.
Robison,
“ They [the leases] do not authorize the purchaser to take and use seven-eighths or any other mere fractional part of the oil or gas in the land leased. The purchaser instead buys all the oil and gas, for a stipulated price, part *282 of the price being measured by the value of a certain fraction of the produced oil and gas, which is a very different thing from the value of that fraction of the oil and gas in place. The leases convey all the oil and gas in granting the right to find, produce, and appropriate all of them, in consideration of the payment of stipulated sums and also the value of a stated fraction of the oil and gas produced.”
Property sold or otherwise disposed of by the government, either state or national, in order to raise revenue for government purposes, is in a broad sense a government instrumentality, with respect to which neither the property itself before sale, nor its sale by one government, may be taxed by the other. But it does not follow that the same property in the hands of the buyer, or his use or enjoyment of it, or the income he derives from it, is also tax immune.

v.
United States,
But the remote and indirect effects upon the one government of such a non-diseriminatory tax by the other have never been considered adequate grounds for thus aiding the one at the expense of the taxing power of the other. See

v.
Bunn,
Property which has thus passed from either the national or a state government to private ownership becomes a part of the common mass of property and subject to its common burdens. Denial to either government of the power to tax it, or income derived from it, in order to insure some remote and indirect antecedent benefit to the other, would be an encroachment on the sovereign power to tax, not justified by the implied constitutional restriction. See Weston v. Charleston, supra, p. 468. The interest which passed to petitioner here, as defined by the laws of the State, is not distinguishable from the mining claims, acquired in lands of the United States under its statutes, which, together with minerals and ores derived from them, were'held subject to state taxation in Forbes v. Gracey, supra.
True, since restricted, allotted, or tribal lands of Indians are instrumentalities of the Federal Government, it has been held that neither leases of the lands,
