¶1APPEAL FROM THE DISTRICT COURT OF THE UNITED STATES ' FOR THE. EASTERN DISTRICT OF PENNSYLVANIA.
¶2In determining whether the admiralty has jurisdiction over an incom-pleted structure in navigable waters to be used when completed as a governmental aid to navigation,- its location and purpose are’ controlling from the time it was begun. •
¶3The jurisdiction that admiralty has over an incompleted structure in course of construction extends to that 'which is a meré incident to such construction.
¶4. The admiralty has jurisdiction of a libel in rem against a vessel for damages caused by its colliding with an incompleted beacon in course of construction in,, and surrounded by, navigable waters arid which when completed is to be used solely, as a governmental aid to navigation. ' •
¶5186 Fed. Rep. 849, reversed in part.
¶6The .facts, which involve the jurisdiction in admiralty . of the District Court of a libel in rem against a vessel for damages caused by its colliding with an incompleted beacon in navigable water, are stated in the opinion.

¶33A court of admiralty, having rightfully taken jurisdiction of the damage to appellant’s pile driver and barge, should retain it to redress the entire wrong inflicted by the same maritime tort.
¶34Mr. Henry R. Edmunds for appellee:
¶35An injury to a structure affixed to the land and wholly or partially supported by it, is not capable of being redressed in admiralty. The Professor Morse, 23 Fed. Rep. 803; The Maud Webster, 8 Ben. 547, and see following instances in which the propertj'' specified was involved:
¶36A pier, because it is a part of the land, and property on a pier, because it is on land. The Haxby, 95 Fed. Rep. 170.
¶37■ Houses on a wharf, destroyed by a fire originating on a vessel lying thereby. The Plymouth, 3 Wall. 20.
¶38A bridge with a draw, because it is a part of the land. The John C. Sweeney, 55 Fed. Rep. 540; Martin v. West, 222 U. S. 191.
¶39A building on land, struck by the jib boom of a moving vessel. Johnson v. Chicago Elev. Co., 119 U. S. 388.
¶40A swinging bridge, because it is a part of the land. Milwaukee v. The Curtis, 37 Fed. Rep. 705; The Black-heath, 195 U. S. 361, distinguished.
¶41*171An unfinished structure, for whatever purpose intended, is not an aid to navigation. So far as it has anything to do with navigation, it is an obstruction and a source of danger. Neither is it subject to admiralty jurisdiction unless it is an instrumentality of the Government. These two elements must coexist in order to bring the case within the rule laid down by The Blackheath.
¶42A drawbridge is an aid to navigation; It has no other purpose. It is a disadvantage to the bridge itself. It is never employed except where vessels have a right to pass. It is thus an aid to navigation just as truly as a beacon is, though in a different way. Yet an injury to it is not cognizable in admiralty. The John C. Sweeney, 55 Fed. Rep. 540; Martin v. West, 222 U. S. 191; So also a swinging bridge. Milwaukee v. The Curtis, 37 Fed. Rep. 705. The reason is obvious. The drawbridge is not a Government aid to navigation.
¶43Since The Blackheath was reported, two cases, Cleveland Terminal Co. v. Steamship Co., 208 U. S'. 316, and The Troy, Id. 321, have come before this court, and it has decided that the doctrine of The Plymouth is still in force, unaffected by The Blackheath.
¶44Although the injury was committed in navigable water; there is no case actually deciding that the sole test of jurisdiction in cases of tort is locality. The true meaning of the rule of locality in cases of maritime torts is that the wrong and injury complained of must have been committed wholly upon the high seas or navigable waters. The rule goes no farther than this. The Plymouth, 3 Wall. 34.
¶45A tort must be committed wholly upon navigable waters, but the converse is not true. It is not the law that everything that takes place upon navigable waters is cognizable in admiralty. Such a doctrine would lead to absurd consequences. If a malicious or negligent act were committed by a bather in the surf at Atlantic City, *172causing the death of another by drowning, the widow would proceed to obtain redress by filing a libel, on the ground that the cause of action arose wholly in navigable water.
¶46Whether a certain tort is maritime must be resolved according to the character and locality of the injured thing. Martin v. West, 222 U. S. 191, 197; Atlantic Transport Co. v. Imbrovek, 234 U. S. 52; Campbell v. Hackfeld Co., 125 Fed. Rep. 696; Cleveland Terminal R. R. v. Cleveland S. S. Co., 208 U. S. 316, 321.
¶47The temporary platform was placed around the building which was under construction solely for the purpose of aiding in the work; and, in its legal aspect was on the same footing as the tools used by the laborers. It was not maritime in its character or in its object.
¶48The jurisdiction of the Federal courts in admiralty cases is' given by the Constitution. Not even Congress has power to add anything to it. If a subject is not within this class, the courts can take no cognizance of it, whether or not it is connected, as to time and place, with some others which they clearly have power to adjudicate. The St. David, 209 Fed. Rep. 985.
¶51delivered the opinion of the court.
¶52The appellant filed a libel in rem in the admiralty against the steamship “Raithmoor” to recover damages for tort. The steamship, coming up the Delaware River on the evening of July 18, 1909, collided with a scow and pile' drver belonging to the appellant, and also with a structure which the appellant was erecting for the United States to serve as a beacon, and with a temporary platform used in connection with the work of construction. For the injury to the scow and pile driver, a decree was entered in favor of the libellant. But the District. Court *173held that there was no jurisdiction in the admiralty of the claim for the damage to the structure and platform, and the libellant appeals. The Raithmoor, 186 Fed. Rep. 849.
¶53The District Court thus states the character and location of the structure:
“The company” (the appellant) “was executing an independent contract with the United States, which bound them to furnish the necessary materials, labor, plant, etc., and to erect in place a foundation pier to receive a gas beacon. The work was under the continual supervision of a government official, but had neither been finished nor accepted. The structure was to consist of three cylindrical piles of reinforced concrete to be sunk about 19-^ feet into the bottom of the river, and to project 12 feet above mean high water, these to be covered with a sheet steel cap. The piles were to be encased in steel arid to be protected also by depositing rip-rap around them to a specified height. When completed, the pier was to be used solely as a beacon on the edge of a navigable channel that has not yet been made ready, and the government was to install upon the cap a lamp and other appliances. The site is three-fourths of a mile from the eastern or New Jersey shore, and about two miles from the western or Delaware shore, of the river, and is surrounded by navigable water, about twenty-seven feet deep at low tide. The work was begun in June, and at the time of the collision was approaching completion. The piles were in place, and not much remained to be done except to put the metal cap into place and deposit the rip-rap. The necessities of the work required a temporary platform to be built close to the concrete piles. This was of wood, about 15 feet square, and rested upon wooden piling driven into the bottom of the river.” Id., p. 850.
¶54The decisions of this court with respect to the jurisdic*174tion of the admiralty in cases of tort make the question to be determined a very narrow one. In The Plymouth, 3 Wall. 20, 36, it was broadly declared that "the whole, or at least the substantial cause of action, arising out of the wrong, must be complete within the locality upon which the jurisdiction depends — on the high seas or the navigable waters.” Accordingly it was held that a libel for damage to a wharf and storehouses caused by a fire started on a vessel through negligence was beyond the limit, of admiralty cognizance, as the damage was wholly done, and the wrong was thus consummated, upon the land. Upon this ground, the jurisdiction of the District Court to entertain a petition for the limitation of the liability of the ship owner in such a case was denied in Ex parte Phenix Insurance Co., 118 U. S. 610. The principle was restated in Johnson v. Chicago &c. Elevator Co., 119 U. S. 388, 397. And see Knapp, Stout & Co. v. McCaffrey, 177 U. S. 638, 643; Homer, Ramsdell Co. v. La Compagnie Générale Transatlantique, 182 U. S. 406, 411. But in The Blackheath, 195 U. S. 361, a distinction was drawn, and the- jurisdiction of the admiralty was upheld in the case of an injury caused by a vessel in negligently running into a beacon which stood fifteen or twenty feet from the channel of Mobile river, or bay, in water twelve or fifteen feet deep, and was built on piles driven firmly into the bottom. The court pointed out the essential basis of the decision, in saying: “It is enough to say that we now are dealing with an injury to a government aid to navigation from ancient times subject to the admiralty, a beacon emerging from the water, injured by the motion of the vessel, by a continuous act beginning and consummated upon navigable water, and giving character to the effects upon a point which is only technically land, through a connection at the bottom of the sea.” (Id., p. 367.) It was suggested in the concurring opinion of Mr. Justice Brown (Id., p. 368) that the decision *175practically overruled the earlier cases, and that it recognized the principle of the English statute extending the jurisdiction of the admiralty court to “any claim for. damages by any ship.” This consequence, however, was expressly denied in Cleveland Terminal R. R. v. Cleveland Steamship Co., 208 U. S. 316, 320. In that case it was decided that the admiralty did not have jurisdiction of a claim for damages caused by a vessel adrift, through its alleged fault, to the center pier of a bridge spanning a navigable river and to a shore abutment and dock. Referring to The Blackheath, and drawing the distinction we have noted, the court said: “The damage” (that is, in The Blackheath) “was to property located in navigable waters, solely an aid to navigation and maritime in nature, and having no other purpose or function. . . . But the bridges, shore docks, protection piling, piers, etc., ” (of the Cleveland Terminal Company) “pertained to the land. They were structures -connected with the shore and immediately concerned commerce upon land. Noné of these structures were aids to navigation in the maritime sense, but extensions of the shore and aids to commerce on land as such.” The decision in The Troy, 208 U. S, 321, was to the same effect. The steamer Troy had collided with the center pier of a swinging span over the St. Louis river, a navigable stream, and the jurisdiction of the admiralty of a libel for the injury was denied. See, also, Phoenix Construction Co. v. The Poughkeepsie, 212 U. S. 558; Martin v. West, 222 U. S. 191, 197.
¶55If then, in the present instance, , the metal cap of the beacon had been in place, the rip-rap deposited, and the beacon put into actual service, the case would fall exactly within the ruling of The Blackheath and the admiralty would have jurisdiction although the structure was attached to the bottom. There would be no difference in the two cases which would afford the slightest ground for argument. If, on the other hand, simply because of the *176incompleteness of thé beacon, it is to be exclusively identified with the land and its intended purpose is to be disregarded, the admiralty would have no jurisdiction. We think that a distinction based solely on the fact that the beacon was not fully completed would be a needless refinement, — a nicety in analysis not required by reason or precedent.. We regard the location and purpose of the structure as controlling from the time the structure was begun. It was not being built on shore and awaiting the assumption of a maritime relation. It was in course of construction in navigable waters, that is, at a place where the jurisdiction of admiralty in cases of tort normally attached, — at least in all cases where the wrong was of a maritime character. See The Plymouth, supra; Atlantic Transport Co. v. Imbrovek, 234 U. S. 52, 58-61, and cases there cited. The relation of the structure to the land was of the'most technical sort, merely through the attachment to the bottom; it had no connection, either actual or anticipated, with commerce on land. It was simply to serve as an aid to navigation, and while it had not yet been finished and accepted, it was being erected under the constant supervision of a Government inspector acting under the authority of the United States in the improvement and protection of navigation. It is urged that the Government might abandon its plan; but there has been no abandonment. The question is not as to an abandoned mass, but as to a beacon in course of erection. Even a completed beacon might be abandoned and whatever question might arise in such a case is not presented here. Again, an analogy is suggested to the case of a vessel which is being constructed on shore, but the argument falls short, as it is to be remembered that as soon as a vessel is launched, although still incomplete, it is subject to the admiralty jurisdiction. Tucker v. Alexandroff, 183 U. S. 424, 438. This is not the case of a structure which at any time was identified with the shore, but from the beginning *177of construction locality and design gave it a distinctively maritime relation. When completed and in use, its injury by a colliding ship would interfere, or tend to interfere, with its service to navigation; and, while still incomplete, such an injuiy would tend to postpone that service. We know of no substantial reason why the jurisdiction of the admiralty should be sustained in the one case and denied in the other.
¶56With respect to the temporary platform, it is to be observed that this was a mere incident to the structure and as such the jurisdiction would extend to the claim for the damage to it.
¶57The decree, so far as it dismissed the libel for want of jurisdiction, is reversed, and the cause is remanded for further proceedings in conformity with this opinion.
¶58It is so ordered.
