delivered the opinion of the Court.
These cases are here on writ of certiorari to the United States Circuit Court of Appeals for the Eighth Circuit.
In 1917 the Prairie Oil and Gas Company acquired by assignment an oil and gas lease, together with an extension thereof, and entered into possession of the land covered thereby. The lessor was William G. Twist, a citizen of the Cherokee Nation to whom the land had been allotted. After Twist’s death and the expiration of the original lease, his children brought this suit in a state court of Oklahoma seeking relief on the ground that the extension was invalid because of fraud and also because certain statutory requirements had not been observed. Two causes of action were therein set forth. In one, damages were sought as for an alleged trespass. In the other, ,it was charged that the purported extension of the lease constitutes a cloud upon plaintiff’s title; and the plaintiffs prayed for a declaration as to the ownership, for cancellation of the extension, for quieting of plaintiffs’ title, and for an injunction against further trespass *687 or claim by defendant. Such joinder in a single suit of a cause of action at law with one in equity is permissible under the Oklahoma statute; and under the state law a suit to quiet title may apparently be brought by one out of possession against one in possession. Compiled Oklahoma Statutes, 1921, c. 3, Art. XIV.
The Company, the defendant below, removéd the case to the federal court for eastern Oklahoma on the ground of diversity of citizenship. In the federal court the joinder of an action at law with one in equity is not allowable.
Hurt
v.
Hollingsworth,
*688 The proceedings on the appeals were throughout those customary in an equity cause. The'records were full and complete. They include, among othe^ things, all of the evidence. The decree declared that the defendant is the owner of the extended oil and gas lease cohering eleven-fifteenths interest in the described lands; that two of the plaintiffs, are the owners of the remaining four-fifteenths interest; that these two plaintiffs recover four-fifteenths “ of tEe net proceeds of the oil and gas produced from said land from September 29, 1919 to April 1, 1923 ” (the amount of which was agreed upon); and that “ the amount produced since April 1st, 1923 [be] reserved for further consideration.” Both the plaintiffs and the defendant appealed to thg Circuit Court .of Appeals. Neither party assigned as error that there was lack of jurisdiction -in:equity or a lack of equity. The errors assigned disclosed claims that the District Court erred in admitting evidence; in excluding evidence; in refusing to set aside the extension; in making certain findings; in making certain rulings; in decreeing that the defendant was the -owner of the eleven-fifteenths interest in the extended lease; in decreeing that two of the plaintiffs were the owners of four-fifteenths; in concluding that the extension of the lease held by the defendant constituted a cloud upon the title of these two and in decreeing the removal of that cloud; in concluding that they were entitled to two-fifteenths of the net proceeds and in ordering payment of the agreed amount.
The Court of Appeals held that it was without power to review the case as upon an appeal from an equity cause, or to consider any of the errors assigned. Because in its opinion there was a plain, adequate and complete remedy at law, it held that the case must be deemed to have been tried in the District Court as an action at law without a jury. And it applied the rule, that where an action at law is tried without' a jury and there has been
*689
no waiver of the jury in the manner prescribed by the statute and no special findings or bill of exceptions, the appellate court is without power to review any question. except those which arise on the process, pleadings or judgment. See
Law
v.
United States,
In federal courts, as in others, a plaintiff has a right to choose whether he will seek to enforce a legal or an equitable cause of action and whether he will seek legal or equitable relief. He makes his election and proceeds at law or in equity at his peril. See
Perego
v.
Dodge,
The parties cannot, of course, compel the trial court to hear in equity a suit which seeks a legal remedy for a legal cause of action.
Lewis
v.
Cocks,
The decree in the case at bar rests upon the second cause o-f action set forth in the bill and the answer thereto. We must disregard, as the lower court and the parties did, the first cause of action. The features of the second cause of action are all those of a bill to remove a cloud and to quiet title. The bill prays for a declaration of the rights of the respective parties; for the cancellation of an agreement; for an injunction against the assertion of certain rights; and for general relief. The answer embodied what is in effect a cross-bill. The relief sought by the bill and the cross-bill is of a character within the recognized sphere, of federal equity jurisdiction. See
United States
v.
Wilson,
It is true that ordinarily one out of possession may not bring in a federal court a bill to quiet title, against one in possession, because there is a full, adequate and complete remedy at law and the defendant is entitled to a jury trial. See
Whitehead
v.
Shattuck,
The Court of Appeals, being of opinion that the plaintiffs had not established a right to relief in equity, because there was a plain, adequate and complete remedy at law, might, on the undisputed facts, have reversed the decree oh that ground without considering the specific errors assigned; and, rightly or wrongly, it might have ordered the bill dismissed without prejudice to the remedy at law; or might conceivably have ordered the case transferred to the law docket; or might have considered the case on the merits as on an equity appeal, in the view that at such stage of the proceedings it was desirable to hold that the objection to the equity jurisdiction had been waived. Compare
Southern Pacific Co.
v.
United States,
Because the Court of Appeals should have considered the errors assigned as in an equity cause, but did not, we reverse its judgment and remand the case to it for further proceedings in accordance with this opinion. See

Notes
In No. 302 four cases, each concerning a different lease, were consolidated. The facts stated in the opinion are those of one of these; The same question is presented in No. 301 concerning a fifth lease.
