WATERMAN, Circuit Judge.

This is an appeal from an interlocutory decree in the admiralty holding appellant, M. J. Tracy, Inc., liable for damages sustained by libellant's tank barge, Morania No. 140, when it fetched up on a sunken coal barge owned by Tracy. Liability was predicated upon Tracy's alleged negligence in failing to mark its sunken barge, Cape Erwin, as required by 33 U.S.C. § 409. Various impleading petitions were served, but all of these actions have been dismissed and none is involved in the present appeal.

The record on appeal contains little more than the pleadings, as amplified by answers which Tracy made to interrogatories filed by the libellant, and a stipulation as to uncontested facts. No witnesses were called, and Tracy offered no evidence at trial. The sole question presented is whether the libellant, Morania Barge No. 140, Inc., established a prima facie case of negligence on the part of Tracy sufficient to support the decree of the trial court. We hold that such a prima facie case was established and therefore we affirm the decree below.

The facts, as stipulated by the parties, were as follows:

"At approximately 1300 hours of February 27, 1958, a collision occurred between the tanker P.W. Thirtle and the loaded coal barge Cape Erwin in the navigable channel of the Arthur Kill south of the Goethals Bridge. * * * The Cape Erwin was owned by M J Tracy, Inc.

"Approximately five to 10 minutes after the collision the Cape Erwin sank in the navigable waters of the channel. When the Cape Erwin sank she submerged completely under the surface of the water.

"It is further stipulated * * * that after the Cape Erwin had sunk, the Morania Barge No. 140, while in tow of the tug Morania No. 8 fetched up and stranded on the Cape Erwin. At the time the Morania No. 140 fetched up on the sunken Cape Erwin, no wreck marker or wreck buoy had been placed on the site."

The libellant alleged that the collision between Morania No. 140 and the submerged Cape Erwin occurred shortly after 2:30 P.M. on February 27. Tracy's answer to the libel fixed the time at shortly after 3:30 P.M. The interval of time between the sinking of the Cape Erwin and the collision here at issue, therefore, was from one hour and twenty minutes, as found by the trial court, to approximately two hours and one half, as admitted in appellant's pleadings.

Although 33 U.S.C. § 409 is a criminal statute, it reflects a legislative judgment of the standard of care to which owners of sunken vessels should be held in civil actions. Sullivan v. P. Sanford Ross, 263 F. 348 (2 Cir., 1920). The statute provides as follows:

"* * * And whenever a vessel, raft, or other craft is wrecked and sunk in a navigable channel, accidentally or otherwise, it shall be the duty of the owner of such sunken craft to immediately mark it with a buoy or beacon during the day and a lighted lantern at night, and to maintain such marks until the sunken craft is removed or abandoned, and the neglect or failure of the said owner so to do shall be unlawful; * * *."

If the statute were interpreted literally, it would be undeniable that Tracy was in violation of its provisions because of failure to mark the Cape Erwin after its sinking in a navigable channel. From such a statutory violation, Tracy's negligence in causing the subsequent collision of Morania No. 140 with the wreck would be presumed. Sullivan v. P. Sanford Ross, supra; Reading Co. v. Pope Talbot, Inc., 192 F. Supp. 663 (E.D. Pa.), aff'd 295 F.2d 40 (3 Cir., 1961). Section 409 has not been interpreted literally, however. Although it has been described as a "drastic statute," The Chambers, 298 F. 194, 196 (S.D.N Y 1924), aff'd Director General of Railroads v. Molyneaux, 13 F.2d 1021 (2 Cir., 1926), and one which imposes a "very high degree of care * * * upon the owners of wrecks," Sullivan v. P. Sanford Ross, Inc., supra 263 F. at 350 (dissenting opinion), the courts have found no violation of its provisions where owners have taken steps to mark their sunken vessels within a reasonable time after receiving notice of the sinking. Petition of Anthony O'Boyle, Inc., 161 F.2d 966 (2 Cir., 1947); The Anna M. Fahy, 153 F. 866 (2 Cir., 1907).

From these authorities, appellant argues that to establish a prima facie case of dereliction of statutory duty under § 409, a libellant must affirmatively plead and prove, in the first instance, the failure of the owner to mark a sunken vessel (1) within a reasonable time (2) after he has received notice of the sinking. Although appellant in this case admittedly received notice of the sinking of its barge, no evidence has been offered as to the time the notice was received. Libellant failed, thus, to establish, it is contended, that Tracy neglected to mark the wreck within a reasonable time after the notice was received.

There have been brought to our attention, however, no cases in which so heavy a burden of going forward with the evidence was imposed upon a libellant claiming negligence for failure to comply with § 409. Indeed, our decision in Berwind-White Coal Mining Co. v. Pitney, 187 F.2d 665 (2 Cir., 1951) suggests a different allocation of the burden of proof. There, the first of several ships collided with appellant's wrecked coal barge approximately two and one half hours after the barge sank in a navigable channel. In holding the barge owner at fault for failure to mark the wreck, we said:

"This appellant, who was the owner, did nothing in that regard although as early as two hours before the first accident at the wreck its general foreman Nelson had notice the barge had sunk in the navigable channel. In the absence of evidence showing that Nelson couldn't reasonable [sic] have had time to have the wreck marked before the vessels struck it, we accept the trial judge's holding that the appellant violated the wreck statute as to all of them." 187 F.2d at 669.

In The Chambers, 298 F. 194 (S.D.N.Y. 1924), aff'd Director General of Railroads v. Molyneaux, 13 F.2d 1021 (2 Cir., 1926), respondent's sunken vessel had been marked some days prior to the collision of another vessel with it. At the time of the collision, however, the wreck was not buoyed, for the marker had unexplainedly carried away prior to the accident. In holding the owner of the wreck liable for the resulting damages, Learned Hand, J., then sitting in the District Court, stated:

"The statute [ 33 U.S.C. § 409] imposes a continuous duty and I think that an owner should show why he did not watch the buoy, what efforts he made, and what prevented him, when it carried away, from substituting a new one." 298 F. 195.

The heavy burden of going forward with the evidence which appellant asks us to impose on libellant here finds no more support in reason than it does in authority. In its answer to the libel, Tracy admitted to having received notice of the sinking of the Cape Erwin. The barge sank in a heavily traveled channel, the Arthur Kill, but a few miles from appellant's place of business in New York City. Whether the notice reached Tracy immediately or some time after the sinking, whether employees of Tracy were available and had the implements at hand to mark the wreck, and whether Tracy took steps to impress these or other agents into service for purposes of complying with § 409 are all matters peculiarly within the knowledge of Tracy. Under these circumstances, once a substantial delay in placing suitable markers has been proved, the owner should have the burden of going forward with evidence to establish the discharge of his statutory duty to mark his sunken vessel. The masters of vessels plying navigable channels should be free to assume that the channel is clear of sunken vessels unless markers are present as required by law.

Although the appellant-respondent offered no evidence at trial, Tracy now relies upon certain allegations or "admissions" in the pleadings and in Tracy's answers to interrogatories, propounded and introduced into evidence by the libellant, to show that (1) Tracy made some efforts to have the Cape Erwin marked prior to the collision here at issue, and (2) Morania was at fault in failing to heed warnings prior to the collision. An examination of the record before us reveals no evidence on these issues helpful to appellant's position.

As part of its libel, Morania Barge No. 140, Inc., alleged:

"Fifth: That on February 27, 1958, at about 1:00 P.M., E.S.T., at the Calso Dock at Perth Amboy, New Jersey, * * * the tankbarge `Morania No. 140' was taken in tow by the tug `Morania No. 8' bound for 30th Street and the East River via Arthur Kill and the Kill Van Kull. * * *

"The voyage proceeded without incident until about 2:30 P.M., E.S.T., as the flotilla then in mid-channel approached the Goethal's Bridge, spanning the Arthur Kill, when, as the flotilla rounded the bend to starboard in the Gulf Port reach of the Kill, several craft were observed tied up and at rest on the starboard bank above the dock, where some work was in progess. Among the craft there, were two tugs, two barges and the U.S. Coast Guard crash boat with an `A' frame derrick working inshore. These craft, abreast of each other, extended into the channel to about the same distance as the face of the dock, slightly to the south, and in no way obstructed or impeded navigation in the channel. As the flotilla came about abreast of these craft, one of the tugs flashed his white searchlight several times and someone shouted. The motors of the tug `Morania No. 8' were immediately stopped to hear what was shouted and the flotilla drifted in the tide in mid-channel making about five miles per hour over the ground. A man on the craft at the bank pointed towards the bridge, but there was nothing ahead to be seen in the channel. Moreover, the motors of the `Morania No. 8' were then reversed and the headway of the flotilla almost stopped when the tankbarge `Morania No. 140' fetched up on a submerged and unmarked object (subsequently found to be the sunken, laden coal barge `Cape Erwin') and became impinged on that object."

The admissions in pleadings are to be construed together with the remainder of their content and are to be given effect subject to what qualifications there may be contained therein. Baker, Carver Morrell Ship Supplies, Inc. v. Mathiasen Shipping Co., Inc., 140 F.2d 522 (2 Cir., 1944). Morania has not admitted that any craft was patrolling the channel or was present near the sunken Cape Erwin at the time the Morania flotilla rounded the bend in the Gulf Port reach of the Kill. Although some attempts to warn the Morania flotilla were made as it came abreast of several craft arrayed on the starboard bank at the dock of Gulf Port, and the motors of the Morania tug were stopped to determine the reason for the signals, Morania alleges that the warnings came too late to avoid the collision with the submerged Cape Erwin.

In its answers to Morania's interrogatories, placed in evidence by the libellant, Tracy does not claim that the channel was being patrolled as the Morania flotilla rounded the bend at Gulf Port. Tracy does allege, however, that prior to the time Morania No. 140 fetched up on the submerged Cape Erwin, the tug Pottsville blew alarms from the vicinity of the Gulf Port Dock and the United States Coast Guard picket boat No. 4066 "had proceeded down stream to the Morania No. 8 and had run parallel with her giving warning of the sunken barge."

On this record we find no error in the trial court's determination that Morania was not at fault in the subsequent collision with the sunken Cape Erwin. In The E.M. Millard, 285 F. 94 (S.D.N.Y. 1922) a similar defense to liability was based upon warnings given to the libellant's vessel as it approached a submerged wreck. Finding respondent liable notwithstanding the attempted warnings, the court stated:

"There is some suggestion that a man on the dock waved and shouted a warning to the Millard, but there is no proof that the warning, if given, was heard or seen, and there is no duty upon a tug captain to look for a warning from such a direction in connection with a danger to navigation which should have been properly buoyed." 285 F. at 95.

The language of the Supreme Court in The City of New York, 147 U.S. 72, 85, 13 S.Ct. 211, 216, 37 L.Ed. 84 (1893) is also pertinent:

"Where fault on the part of one vessel is established by uncontradicted testimony, and such fault is, of itself, sufficient to account for the disaster, it is not enough for such vessel to raise a doubt with regard to the management of the other vessel. There is some presumption at least adverse to its claim, and any reasonable doubt with regard to the propriety of the conduct of such other vessel should be resolved in its favor."

And see Reading Company v. Pope Talbot, Inc., 192 F. Supp. 663 (E.D.Pa.); aff'd 295 F.2d 40 (3 Cir., 1961).

Moreover, evidence of third party attempts to warn the Morania flotilla prior to the collision does not explain Tracy's failure to mark its wrecked barge. There is no evidence on the record before us that Tracy in any way instigated, or was connected with, or responsible for, these attempted warnings. Furthermore, even if it were established that Tracy had requested the Coast Guard to patrol or mark the sunken barge, such a request would not discharge Tracy's non-delegable, statutory duty to mark the wreck. Berwind-White Coal Mining Co. v. Pitney, 187 F.2d 665 (2 Cir., 1951).

Morania having established a prima facie case of negligence for failure to mark the sunken Cape Erwin, and Tracy having offered no evidence to explain its delay in performing its statutory duty, the decree of the trial court must be, and is, affirmed.
