The issue is purely one of law, and narrows considerably under the able briefs' and arguments submitted. *812 The city contends that under its charter, which provides that its mayor and council “shall have full power and authority and they shall provide by ordinance for the assessment, levy and collection of an ad valorem tax on all real and personal property which under the laws of this State is subject to taxation within the incorporate limits of said city,” it is authorized to collect a property tax upon the basis appearing in the statement of facts. The ordinance relied upon by the city does not undertake specifically to reach such a situation or to establish any “formula” for taxing such movable personalty in transit, but provides a levy on “all real and personal property which under the laws of the State and under the charter of the city as amended is subject to taxation by the city.”' The motor corporation, while conceding, under authorities which will bq mentioned, that the State has the power to render subject to taxation property moving in and out of its borders as here shown, contends that in the absence of a statute which would have the effect of giving a taxable situs to such personalty, by changing the rule that unless actually located within the State, it would follow the- domicile of its non-resident owner, the municipality is wholly lacking in the authority claimed by it. In the presentation of the case there has been much helpful discussion with reference to the principles that have by now been laid down with regard to the power of a State to tax or authorize the taxing of that class of property involved. Some attention will later be given to the decisions from various jurisdictions dealing with that question; but we have reached the conclusion that the primary question here to be determined will depend upon the laws of our own State and the decisions of our own courts, although it is admitted that this is a case of first impression so far as these facts are concerned.
At the very outset it may be observed: “A municipal corporation can levy no tax, general or special, upon its inhabitants, or upon, the property therein, unless the power to do so has been plainly and unmistakably conferred by the State.

A further rule of ancient origin and of equally general application is that personalty as respects its situs for taxation follows the domicile of the owner.

But it is contended by the city that since the State by its charter provision granted to it the right to levy “an ad valorem tax on all real and personal property which under the laws of this State is subject to taxation within the incorporate limits of said city,” and since under our general taxing statute (Code, § 92-101) all real and personal property owned by residents or non-residents is liable to taxation, the city may proceed as it has undertaken to do. If the property of the motor corporation sought to be taxed was located within the city, or, under such rules, as announced in
Suttles
v.
Northwestern Mutual Life Insurance Co.,
supra, had acquired a situs within its limits, it would of course be subject. It is to be remembered, however, that the city is not undertaking in this case to tax any specific property “within the incorporate limits of said city.” In fact it is not undertaking to tax any specific property anywhere, but rather a '“daily average” of the composite value of such property of the motor corporation as may be moved within
*816
and without the city. The city does not contend that the trucks being moved into and out of its limits were physically.present on the taxing date in such. a. way as to render them taxable under ordinary rules as the property of a non-resident. The assessment is based upon an average of five trucks and upon an average value of one of such trucks, as we take it, virtually conceding that no one of the trucks would be subject as such to the ordinary property tax. While it is true, as was held in
Johnston
v. Macon, 62
Ga.
645 (6), that the'State “may grant the power over any of its own subjects of taxation; and the municipal authorities may tax under the grant whether the State see fit to exercise the power on its own account or not,” that principle would not seem to clothe the municipality with power to declare a situs of property, so as to render it taxable where otherwise it was not taxable. It has already been pointed out that the State may separate such movable property and detach it from the anchorage of its owner’s domicile
(Walton County
v.
Morgan County,
supra); and this has been generally held on questions of due process under the United States constitution. Pullman Palace Car Co.
v.
Pennsylvania,
In Mississippi, where the general taxing statute is similar to our own, a statute was enacted providing for the taxation of movable 'railroad property. Previously such property had apparently been left to stand under the normal rules; to be taxed if it had acquired
*817
a situs under the rule; otherwise to follow the domicile of its nonresident owner. After the enactment of their statute the taxing authorities sought to use its formula and machinery to assess the Union Tank Car Company on account of taxes claimed for previous years. That resulted in litigation reported in State ex rel. Knox
v.
Union Tank Car Co.,
“ ‘This peculiar property, which has furnished the topic of so much discussion, is held to be situated, in the absence of a special statute, in the town where the principal office of the corporation is; that is, at the corporate residence. Without the help of a statute, it is incapable of acquiring a permanent locality or situs séparated from the owner’s residence,’ citing: ‘Mohawk etc. R. R. Co. v. Clute, 4 Paige [N. Y.] 384; Appeal Tax Court v. Western Md. R. R. Co.,50 Md. 274 ; Philadelphia, Wilmington etc. R. R. Co. v. Appeal Tax Court,50 Md. 397 ; Appeal Tax Court v. Northern Cent. Ry. Co.,50 Md. 417 ; Appeal Tax Court v. Pullman Palace Car Co.,50 Md. 452 ; Kansas City etc. R. Co. v. Severance,55 Mo. 378 ; City of Dubuque v. Illinois Cent. R. R. Co.,39 Iowa, 56 ; Orange etc. R. R. Co. v. Alexandria, 17 Grat. [58 Va.] 176.’
“A dependable authority supporting this view is Marye v. B. & O. R. R. Co.,127 U. S. 117 ,8 S. Ct. 1037 , 32 L. ed. 94. This ease arose over an attempt by the State of Virginia to impose and collect a tax on movable property, engines, cars, etc., of a Maryland corporation. The Supreme Court of the United States held, that: ‘It is not denied, as it cannot be, that the State of Virginia has rightful power to levy and collect a tax upon such property used and found within its territorial limits, as this property was used and found, if and whenever it may choose, by apt legislation, to exert its authority over the subject.’ ”
*818
The Mississippi court quoted further from the Marye case, where it was pointed out upon authority that before such property otherwise having its taxable situs at the domicile of its owner could be subjected to taxation in Virginia, an
appropriate
statute would be necessary. To follow the rule somewhat further, in Mississippi we find in City of Jackson
v.
Dixie Greyhound Lines Inc.,
The city places strong reliance upon Johnson Oil Refining Co.
v.
Oklahoma,
Another case relied upon by the city is Union Tank Car Co.
v.
McKnight, 84 Fed. 2d, 421. In that case tank cars belonging to a New Jersey corporation were leased to an Illinois refinery for transportation of petroleum products in interstate commerce, and the Circuit Court of Appeals held that under the Illinois statute, the terms of which, it was said, describing taxable property, “are most comprehensive and therefore are capable of incompassing rolling stock belonging to a foreign corporation habitually found in the State,” the taxing of the average number of cars present in the State could be sustained. For interpretation of the State statute they relied upon Keith Railway Equipment Co.
v.
Board of Review,
Thus from what has been said we come to the conclusion as announced by Simpson, J., of the Alabama Supreme Court in City of Bessemer
v.
Southern Railway Co., supra, that while the principle on which this character of taxes has been sustained is that it lies within the power of the State to separate the situs from the ownership of personal property as to that class of personalty which is continuously kept and used, it should pay a part of the burden of taxation; and while it might be within the power of the legislative department in fixing the class of property and providing for its assessment to make provision for municipal taxation, unless it does so, the levying of such a tax by. the municipality would be beyond its power. The State could not permit the municipality to assume such a legislative function as to change the existing tax situs. Compare
