delivered the opinion of the court.
This ease is here upon writ of error and certificate presenting the question of jurisdiction of the District Court. It comes under § 238 of the Judicial Code, and presents to this court the question of jurisdiction only. The suit was begun on November 5, 1904, in the United States Circuit Court for the District of Connecticut. On May 24,1905, a substituted complaint was filed. The object of. the suit was to recover for alleged breaches of a certain indemnity contract set forth in the complaint. In this substituted complaint, as well as in the original complaint, the allegation as to diverse citizenship is that plaintiff is a citizen of the State of Michigan, and defendants are citizens of the State of Connecticut. On August 3, 1907, an answer was *566 filed, in which it was admitted that the defendants were citizens of the State of Connecticut, and it was averred that the defendants had no knowledge or information as to the citizenship of the plaintiff, and would “leave him to proof thereof.” On April 27, 1911, the defendants filed a motion to dismiss the suit for want of jurisdiction. On October 5,1911, defendants filed another motion to dismiss for want of jurisdiction. On October 6, 1911, the plaintiff filed a motion to strike the last-mentioned motion from the files. Both of the motions to dismiss were upon the ground that the plaintiff was not a citizen of the State of Michigan but was a citizen of the State of Connecticut. The motion of the plaintiff to strike the last-mentioned motion from the files Ayas upon the ground, among others, that the motion was an improper and irregular method of raising the question of jurisdiction and because that matter was already in issue under the allegations of complaint and answer.
After the taking effect of the Judicial Code on January 1, 1912, the case was transferred to the District Court of the United States for the District of Connecticut. On August 26, 1912, a jury was impanelled, and the case came on for trial. The court directed that the trial should proceed upon the question of jurisdiction. Thereupon the parties proceeded to offer testimony upon the question of plaintiff’s residence. At the conclusion of this testimony, the court found that the plaintiff and defendants were citizens of the State of Connecticut at the time the action was begun, and accordingly dismissed the suit upon the sole ground of want of jurisdiction, and ordered the jury discharged from further consideration of the case.
The act of March 3, 1875, c. 137, 18 Stat. 470, 472, § 5, now § 37 of the Judicial Code, provides:
“If in any suit commenced in a district court, or removed from a state court to a district court of the United States, it shall appear to the satisfaction of the said dis *567 trict court, at any time after such suit has been brought or removed thereto, that such suit does not really and substantially involve a dispute or controversy properly within the jurisdiction of said district court, or that the parties to said suit have been improperly or collusively made or joined, either as plaintiffs or defendants, for the purpose of creating a case cognizable or removable under this chapter, the said district court shall proceed no further therein, but shall dismiss the suit or remand it to the court from which it was removed, as justice may require, and shall make such order as to costs as shall be just.”
This section defines the duty of the District Court of the United States when it shall appear to its satisfaction that the suit does not really and substantially involve a dispute or controversy properly within the court’s jurisdiction. While this section gives the court the right to dismiss a suit when that situation appears, whether the parties raise the question or not, it is the duty of the defendant to bring the matter to the attention of the court, in some proper way, where the facts are known upon which a want of jurisdiction appears.

v.
Young,
' It is also insisted that the court erred in itself considering the testimony and. in not submitting the issue to the jury. But while the court might have submitted the question to the jury, it was not bound to do so,- the parties having adduced their testimony, pro and con, it was the privilege of the court, if it saw fit, to dispose of the issue upon the testimony which was fully heard upon that subject.
Wetmore
v.
Rymer,
It is urged that the delay in making the issue and bringing it to a hearing was such laches upon the part of the defendants as to preclude the consideration of the question. The issue was made when the answer was filed, but for some reason neither party forced the case to trial. Apart from the imperative duty of the court to dismiss the action under the statute, when it appears that the case is not within the jurisdiction of the court, we find nothing in the conduct of the parties to support the suggestion of laches.' If it be true that the statute of limitations would prevent- the beginning of a new action in the, state- court, that fact cannot confer jurisdiction upon a court of the United States in the absence of a showing of diverse citizenship.
As the record -brings up the testimony upon which the court below decided the question, it becomes the duty" of this court to consider it and determine whether the court rightly found that the plaintiff at the beginning of the 'suit was not a citizen of the State of Michigan.

v.
Rymer,
The question is, Had he lost his domicile in Michigan and acquired one in Connecticut, so that he was at the beginning of the suit in 1904 in reality a citizen of the last-mentioned. State?
This matter of domicile has been often before this court, and was last under consideration in the case of
Williamson
v.
Osenton,
*570 Applying these definitions to the conduct of plaintiff, we have no doubt that the court was right in holding that he had acquired a new domicile in the State of Connecticut. He removed there with his family, and occupied a house to which he held the title. He owned other real, estate in Connecticut, inherited from his uncle. He took a letter from his church in Michigan to a church in Dan-bury, Connecticut. For about ten years he was not back in Michigan, except for a short time, and then for a temporary purpose. The Michigan homestead and much of the furniture used there were sold upon the removal to Connecticut. For more than ten years he resided continuously with his family in the same house in Danbury, Connecticut. While the- plaintiff did not vote in Connecticut, as far as the record shows, it is in evidence that he declared to another his intention of becoming a voter there. To some witnesses he declared his purpose to reside in Connecticut. As against this testimony, it appears that he left his desk with his brother-in-law in Michigan,, which he declared was for the purpose of “holding his residence there.” To some witnesses he declared his intention to live in Michigan and expressed his preference for that State as a dwelling-place. He continued to pay membership dues to orders to which he belonged in Michigan.
It is apparent from all the testimony that the plaintiff may have had, and probably did have, some floating intention of returning to Michigan after the determination of certain litigation and the disposition of his property in Connecticut should he succeed in disposing of it for what he considered it worth. But as we have seen, a floating intention of that kind was not enough to prevent the new place, under the circumstances shown, from becoming his domicile. It was his place of abode which he had no present intention of changing, that is the essence of domicile.
*571 We find no error in the conclusion of the District Court upon the question of jurisdiction, and its judgment is therefore
A firmed.
