Majority — Hughes C.J.
delivered the opinion of the Court.
The Ohio Oil Company brought this suit in the District Court to enjoin the enforcement of a statute of Louisiana (Act 5 of 1928) imposing a severance tax upon the production of oil. The statute as applied to the complainant was attacked as a violation both of the constitution of Louisiana and of the equal protection clause of the Fourteenth Amendment of the Federal Constitution. It was alleged that the laws of the State afforded no remedy for the recovery of taxes illegally exacted. On appeal from an order denying an interlocutory injunction, this Court decided that the questions presented could not be resolved satisfactorily upon the affidavits submitted, and directed that an injunction should be granted pendente lite on stated terms. 279 U. S. 813 . Trial was had before the District Court, as specially constituted under the applicable statute, and a decree was entered dismissing the bill. 34 Fed. (2d) 47. The complainant appeals.
In the year 1921, the constitution of Louisiana was amended so as to provide that natural resources severed from the soil or water might be classified for the purpose of taxation and that taxes might be “ predicated upon
In 1928, the legislature of Louisiana enacted the statute now in question which amended the prior act so as to tax various natural resources on the basis of the quantity severed. Under this amendment taxes on oil were classified according to gravity and ran from four cents a barrel of 42 gallons on oil of 28 degrees gravity and below, to eleven cents a barrel on oil above 43 degrees gravity (Act 5 of 1928).[2]
1 Section 21 is as follows: “ Taxes may be levied on natural resources severed from the soil or water, to be paid proportionately by the owners thereof at the time of severance. Such natural resources may be classified for the purpose of taxation and such taxes predicated upon either the quantity or value of the product at the time and place where it is severed. No severance tax shall bé levied by any parish or other local subdivision of the State. “ No further or additional tax or license shall be levied or imposed upon oil or gas leases or rights, nor shall any additional value be added to the assessment of land, by reason of the presence of oil or gas therein or their production therefrom.”
2 The text of section 2 of Act 5 of 1928 in relation to oil is as follows: “Taxes on natural resources severed from the soil or water . . . shall be predicated on the quantity severed, and shall be paid at the following rates: *152 “(7) a. On oil of 28 gravity and below, four (4) cents per barrel of 42 gallons. “b. (1) On oil above 28 gravity and not above 31 gravity, four and one-fourth (4%) cents per barrel of 42 gallons. “b. (2) On oil above 31 gravity and not above 32 gravity, five (5) cents per barrel of 42 gallons. “(c) On oil above 32 gravity and not above 36 gravity, eight (8) cents per barrel of 42 gallons. “(d) On oil above 36 gravity and not above 43 gravity, ten (10) cents per barrel of 42 gallons. “(e) On oil above 43 gravity, eleven (11) cents per barrel of 42 gallons.”
Gravity as used in the statute, and in oil price quotations, is not specific gravity,.but what is called Baumé gravity, under’ which the lighter the oil the higher the gravity. The record shows that, generally speaking, crude petroleums are divided into three classes — paraffine base, asphalt base, and mixed base, the last being a combination of paraffine and asphalt base. The higher gravity oils usually have a paraffine base, while the lower gravity oils usually have an asphalt base. All three of these classes are found in Louisiana. In North Louisiana
The process of refining oil is distillation. The evidence is that paraffine base oil in that manner yields gasoline, kerosene, gas oil, some lubricating oil and wax. Gasoline comes off first and is the most valuable component of such oil. Asphalt base oil usually yields a very small amount of gasoline by distillation, the first product ordinarily being gas oil, then lubricating oil, and the residuum, asphalt. The gas oil may- be subjected to the cracking process and gasoline may be obtained in that way. The value of asphalt base oil is largely for the manufacture of lubricating oil, and the value for this purpose is determined by viscosity and sulphur content, not by gravity. The coastal oils of South Louisiana are divided into “A” and “ B ” grades, “ Grade A” being the oils that are useful in the production of lubricating oil, and the other oils being classed as “ Grade B.” While gravity is not the determining factor, it appears from the testimony that “ Grade A” oils must be less than 25 degrees gravity.
Asphalt base oils are produced in North Louisiana in the fields of Pine Island, Urania, Hosston and Bellevue. The last three named are suitable for making lubricating oil, but the Pine Island heavy oil does not have that value. The evidence is that the Urania, Hosston and Bellevue oils, used for that purpose, are practically the same as the coastal “ Grade A” oils-.
Gravity is said to be an index of relative value of oils only in the same pool or district, and oils of different gravity are produced in the same fields and from the same tracts of land and sometimes from the same sand. But it appears that, with respect to paraffine base oils, the higher the gravity, the greater is the gasoline content,
Crude oil as it comes from the wells is run into tanks from which the purchaser sells to pipe lines, the well-recognized market prices being the prices posted by the pipe line companies buying the oil. The complainant states that the oil produced in its Haynesville field was from 33 to 36 degrees gravity; in its Cotton Valley field, one class -was between 28 and 31 degrees gravity and another above 43 degrees gravity; in its Pine Island field, its production was from 37 to 41 degrees gravity. The complainant purchased no crude oil except that, in the Haynesville field, it bought some of the royalty oil of the lessors under its leases. The complainant’s cashier testified at the trial that complainant’s “purchases and sales in each field in which it operates are made on a gravity basis.”
This testimony is not understood to include the Urania field in which the complainant was not operating at the time but had been operating until shortly before. The oil from the Urania field, which was about 20 degrees gravity, as well as that of the Bellevue and Hosston fields in North Louisiana, and the “ Grade A” coastal oils of South Louisiana, were sold at a flat price and not by gravity. “ Grade B ” oil, it was testified, was usually sold on a gravity schedule.
In 1928, the production of oil in Louisiana was about 22,000,000 barrels, of which approximately two-thirds was produced in North Louisiana, and of this amount nearly two-thirds was sold on a gravity basis, and the remainder at a flat price. Of the production in South Louisiana, about one-half was sold on a gravity basis.

The complainant’s contention under the constitution of Louisiana is that the tax is invalid because it was not levied according to either quantity or value. It manifestly is a specific tax at a rate per barrel of 42 gallons, and not strictly ad valorem. The graduation of the tax according to the gravity of the oil does not make it other than a tax according to quantity, that is, per barrel, as the oils of different classes are treated for the purpose of the tax as being in effect different commodities, each of which has its separate tax. We have not been referred to any decision of the state court upon the point and, until that court pronounces otherwise, we see no reason to hold that the tax is unauthorized by the State.
The further argument is made that the classification of oils is unreasonable and hence is not permitted by the state constitution. This is substantially the same question, from the standpoint of state authority, that is presented as a Federal ground of attack under the Fourteenth Amendment.
The complainant contends that the statute of Louisiana, imposing, a tax according to gravity, operates as an arbitrary discrimination; that it discriminates in a wholly unjustifiable manner between the oils of the North Louisiana and South Louisiana fields, and also between the fields producing asphalt base oils. The tax on its production in the Haynesville, Cotton Valley and Pine Island fields is said to be at a rate from about six to seven and one-half per cent, of its value; and on the production in the Urania field, at about five and one-third per cent, of the value; while on the production in fields in South Louisiana, and in the Bellevue field, in North Louisiana, the tax is between three and three and one-half per cent. of the value.
In the present instance it is apparent that a classification according to gravity cannot be regarded as palpably arbitrary. While the Baumé gravity of oils may vary, even in the same fields, it has been used by the oil industry as indicating in a general way, apparently satisfactory for practical purposes, the gasoline ..content. In laying a specific severance tax per barrel, the State was not compelled to make an exact determination of the composition of. each oil produced. At least with respect to oils sold primarily for the gasoline they contained, it cannot be said that the State attempted a hostile and unjustifiable discrimination in graduating its tax according to gravity, when the industry itself resorted to the factor of gravity in fixing the scale of prices for such oils. Further, the complainant is in no position to contest the action of the State in adopting a gravity basis with respect to the production of its oils in the Haynesville, Cotton Valley and Pine Island fields, which constituted over ninety per cent, of its entire production, as the complainant itself sold these oils on a gravity basis. If it be granted, as we think it must be, that the State could adjust the severance tax with respect to such oils according to gravity, the
The question raised by the complainant has particular bearing upon the discrimination with respect to oils under 28 degrees gravity. The complainant in this respect must stand on its own case. Its oil of this sort is its Urania production, and that oil, as well as that of the Bellevue field in North Louisiana, is said to be “ practically the same ” as the coastal “ Grade A” oils of South Louisiana. According to complainant’s own showing, these oils are especially suited to the manufacture of lubricating oil and are dealt in with that in view. While in such cases, gravity is not the criterion, but rather viscosity and sulphur content, these are oils of relatively low gravity, that is, under 28 degrees, and the Louisiana severance tax is a uniform one of four cents a barrel. As these last mentioned oils had a distinct composition and a different utility, the State could impose a tax upon them which was different from that imposed upon the other oils pro
The question is thus reduced to the discrimination alleged with respect to the tax on the complainant’s Urania production as compared with similar oils. As all these oils bear the same tax of four cents a barrel, the complainant manifestly has no ground for complaint on this score unless it can be found in differences in the prices of these oils. Urania oil was sold at seventy-five cents a barrel, while “ Grade A” oil brought $1.20 a barrel. The record affords no explanation of the reason for this wide spread in the price of oils, said to be practically the same and used for the same purpose, unless it be the one advanced by the respondent that the difference is due to the
Judgment affirmed.
