after stating the ease, delivered the opinion of court.
The jurisdiction of the Circuit Court in the suit of Gregory against Pike and Swift rested on the fact that the controversy therein was between citizens of different States, and this was the sole ground on which Gregory removed the cause from the state court to the Circuit Court. The fund was in the Circuit Court because realized out of and substituted for the subject of contention in that suit, and Van Ee recovered on his intervening petition what he claimed to be his share of that fund.
In
Rouse
v.
Letcher,
*646 The Circuit Courts of the United States have cognizance of suits as provided by the acts of Congress, and when their jurisdiction as Federal courts has attached, they possess and exercise all the powers of courts of superior general jurisdiction. Accordingly they entertain and dispose of interventions and the like on familiar and recognized principles of general law and practice, but the ground on which their jurisdiction as courts of the United States rests is to be found in the statutes, and to that source must always be attributed.
Manifestly, the decree in the main suit cannot be revised tnrough an appeal from a decree on ancillary or supplemental proceedings, thus accomplishing indirectly what could not be done directly. And even if the decree on such proceedings may be in itself independent of the controversy between the original parties, yet if the proceedings are entertained in the Circuit Court because of its possession of the subject of the ancillary or supplemental application, the disposition of the latter must partake of the finality of the main decree, and cannot be brought here on the theory that the Circuit Court exercised jurisdiction independently of the ground of jurisdiction which was originally invoked as giving cognizance to that court as a court of the United States.
Appeal dismissed.'
