Concurring opinion of
Mr. Justice Stone.
I concur in the result. It is enough to support it'that, as stipulated in the record, the Virginia assessment was levied against a trustee domiciled in Maryland upon' securities held by it in trust in its exclusive possession and control there, and so is forbidden as an attempt to tax property without the jurisdiction. Brooke v. Norfolk, 277 U. S. 27.

Burton v. United States, 196 U. S. 283, 296; Blair v. United States, 250 U. S. 273, 279; Flint v. Stone Tracy Co., 220 U. S. 107; Light v. United States, 220 U. S. 523, 538.
No attempt was made by Virginia to tax the equitable interests of the beneficiaries of the trust. That the thing taxed or the measure of the tax is different from the equitable interests of the beneficiaries, as affected by the specified contingencies, sufficiently appears from the fact that the one may well have been of different value than the other. In fact, the securities seem to have been assessed at their full value although the equitable interests of the beneficiaries are less than the whole.
It may be that Virginia, following its own view of the nature of vested and contingent interests, might tax the interests of these beneficiaries as though they were the whole, but it is sufficient for present purposes that it has not assumed to do so. In the face of the present record we are not required to speculate how far a tax, forbidden because assessed upon property beyond ..the jurisdiction, may be upheld because it may be passed on to the bene
