delivered the opinion of the Court.
A rich oil field was discovered in Illinois in 1938; Thereupon, this dispute arose between a trustee of a railroad in reorganization tender § 77 of the Bankruptcy Act (11 U. S. C. 205) and other claimants as to the legal,right to drill for and capture fugitive oil under the railroad’s right of way traversing the newly discovered field. The trustee asserts fee simple ownership of the right of way lands with consequent right to reduce the underlying oil to possession. Respondents deny the trustee’s alleged title or that he has any interest in the land beyond a mere easement — a limited right to use the surface for railroad purposes only. They allege that ownership of the fee is in others, from whom they have obtained oil leases. This determinative question of fee simple ownership can be decided only by interpretation,, under Illinois law, of instruménts granting the railroad its right of way.
The questions here are whether the bankruptcy court has summary jurisdiction to adjudicate ownership of the right of way lands, and whether that court abused its discretion in ordering the fugitive oil captured and its proceeds impounded pending - adjudication of the ownership.
Petitioner is trustee of the Missouri-Illinois Railroad Co.-, a subsidiary of the Missouri-Pacific Railroad Co., in process of reorganization in the same proceeding with the parent company in the United States District Court
Although they admitted that:; the railroad “had been in possession of the . . . premises” using them for right of way and tracks, respondents denied both that the trustee owned the fee and that the railroad had been, or that the trustee was, in adverse possession of .the oil and other minerals under the right of way.
The bankruptcy court found that the trustee was in “actual possession of the property . . . ., under assertion
Upon consideration of Illinois law, which admittedly must govern, the Court of Appeals reversed with instructions to dismiss the trustee’s petition, concluding that, as interpreted under Illinois law, the instruments relied on by the trustee conveyed an easement only and that the trustee’s possession of the right of way lands under an erroneous claim of fee simple ownership was not such possession of the oil and gas as; to give the bankruptcy court summary jurisdiction to determine fee simple ownership. 1 Conveyances of rights of way in Illinois substantially similar to those here in dispute have been held by the Court of Appeals for the Seventh Circuit, in which Illinois is located, to convey a fee simple title under that state’s law. 2 Because of this conflict and the importance of the question of the bankruptcy court’s asserted summary jurisdiction, we granted certiorari. 3
First.
Bankruptcy courts have summary jurisdiction to adjudicate controversies relating) to property over which they have actual or constructive possession. And the test of this jurisdiction is not title in but possession by the bankrupt at the time of the filing of the petition in bankruptcy.

Here, the trustee succeeded to the physical pos
Second. We are of opinion that it was not an abuse of discretion for the bankruptcy court to authorize the trustee to protect all interests — so far as it appeared possible to do so — by preserving the oil, from waste and depletion, through its extraction and sale with the net proceeds to be impounded until final determination of the controversy over title to the right of way lands.
The verified petition and supporting evidence offered a basis for the District Court’s finding that such steps were necessary to protect the estate’s possible interest in the oil under the right of way. No other method has been suggested whereby such protection against ir
Third.
A court of bankruptcy has an exclusive and nondelegable control over the administration of an estate in its possession.
7
But the proper exercise of that control may, where the interests of the estate and the parties will best be served, lead the bankruptcy court to consent to submission to state courts of particular controversies involving unsettled questions of state property law and arising in the course of bankruptcy administration.
8
And, under the circumstances of this case, we conclude that it is desirable to have the litigation proceed in the state courts of Illinois.
9
An order to the trustee to proceed in the Illinois courts for a decision on the ownership of the fee to the right of way lands will be comparable to one in which the bankruptcy court, preserving the status quo the while, orders a trustee to detérmine in a plenary state court suit the legal right to property alleged by the trustee to have been fraudulently transferred by the bankrupt.

Decision with which the
The judgment of the Circuit Court of Appeals is reversed and that of the District Court is affirmed except insofar as it provides for adjudication of the disputed ownership in the bankruptcy court. The cause is remanded to the District Court with instructions to modify its order so as to provide appropriate submission of the question of fee simple ownership of the right of. way to the Illinois state courts.
