“ In the nature of things, the authorized inquiry is primarily directed to the one who claims that the power of the court should be exerted in his behalf. As he is seeking relief subject to this supervision, it follows that he must carry throughout the litigation the burden of showing that he is properly in court. The authority which the statute vests in the court to enforce the limitations of its jurisdiction precludes the idea that jurisdiction may be maintained by mere averment or that the party asserting jurisdiction may be relieved of his burden by any formal procedure. ”

“ Watt, supra, a suit in equity, the Court said that under the act of 1875 'the objection to the jurisdiction upon a denial of the averment of citizenship is not confined to a plea in abatement or a demurrer, but may be taken in the answer, and the time at which it may be raised is not restricted.' In Wetmore v. Rymer, supra, an action of ejectment, after a verdict and judgment for the plaintiff, the trial court set them aside and entertained defendant's motion to dismiss for want of jurisdiction, giving leave to both parties to file affidavits showing the value of the land in controversy. ”

“ The prerequisites to the exercise of jurisdiction are specifically defined and the plain import of the statute is that the District Court is vested with authority to inquire at any time whether these conditions have been met. They are conditions which must be met by the party who seeks the exercise of jurisdiction in his favor. He must allege in his pleading the facts essential to show jurisdiction. If he fails to make the necessary allegations he has no standing. ”
