Harlan F. Stone,
Murphy Oil Company v. Burnet — Opinion of the Court
“ This is obvious where royalties alone are insufficient to return the capital investment. A distinction between royalties and bonus, which would allow a depletion deduction on the former but tax the latter in full as income, when received, making no provision for a reasonably anticipated production of oil on the leased premises, would deny the 'reasonable allowance for depletion' which the statute provides. The harsh operation of such a rule with respect to taxpayers generally is apparent, and is emphasized by the opportunist character of petitioner's argument here. ”
