On petition for rehearing appellant filed a vigorous and extensive 1 brief. *43 It raises questions regarding all of the main issues which were before the court on the original consideration of the appeal. We granted a rehearing, and the matter was again argued at length, and we again affirm the judgment below.

1. Validity of the Lighterage Clauses.

This court’s opinion rested, essentially, upon the reasoning embodied in the trial court’s decision. Both decisions hold that appellant cannot, by contract, avoid liability for negligent injury to cargo when such injury occurs before the cargo is delivered to a fit and proper wharf. This result stems from an application of Section 1 of the Harter Act, 46 U.S.C. § 190 .

The Harter Act was adopted

In pertinent part, Section 1 of the Act provides:

It would seem, then, that any attempt by the carrier to avoid liability for losses arising before delivery must fail. Once proper delivery has been made, however, the carrier’s liability, as far as the Harter Act is concerned, is at an end. It is, therefore essential •, to determine what a proper delivery is, and when such delivery is completed. The court below and this court on appeal held that a proper delivery, as defined by general maritime law, occurred when the cargo was deposited upon a fit and proper wharf. Appellant contends that there was no common law or maritime rule requiring such delivery and chides this court for discovering such a rule relying upon a dictum in Tan Hi v. United States, N.D.Cal.1950, 94 F.Supp. 432 .

It is true this court did cite and rely upon Tan Hi, but Tan Hi in turn relies upon numerous cases, only one of which is cited or discussed by appel-' lant. These cases establish the existence of a common law (maritime) obligation on the part of the carrier to deposit or “land” the goods on a wharf. As stated in The Mary Washington, 16 Fed.Cas. page 1006, No. 9,229, “The duty of a carrier by water is not fulfilled by transportation from port to port. The goods must be delivered, or at least landed * * And in The Eddy, 1886, 5 Wall. 481, 495 , 72 U.S. 481, 495 , 18 L.Ed. 486 , it was said: “Where the contract is to carry by water from port to port an actual delivery of the goods into the possession of the owner or consignee, or at his warehouse, is not required in order to discharge the carrier from his liability. He may deliver them on the wharf * . * (Emphasis added.) In The Titania, 2 Cir. 1904, 131 F. 229, 230 , the court noted that: “In order to make a valid delivery, which relieves the carrier from liability, it is necessary to show that the goods in question were landed on the wharf * * (Emphasis added.) See also Vose v. Allen, 28 Fed.Cas. page 1283 No. 17,006; The Illinois, 29 Fed.Cas. page 259, No. 17,185; The Grafton, 10 Fed.Cas. page 907, No. 5,656 aff’d. 10 Fed.Cas. page 905, No. 5,655 and 2 Parsons, On Contracts, 5 ed. 1886, pp. 190-193. We also note that the dictum in Tan Hi was quot *44 ed at length, with approval, in Norjac Trading Corp. v. The Mathilda Thorden, E.D.Pa.1959, 173 F.Supp. 23 . Indeed, the carrier’s general maritime obligation not only required it to deposit the goods upon a fit wharf, but to segregate the consignee’s goods from the general cargo and to give the consignee notice of their arrival. (See e. g., The Titania, 2 Cir. 1904, 131 F. 229 .) There is, then, strong support for the existence of a “common law” or maritime rule requiring delivery to a wharf unless the bill of lading specified elsewhere. Appellant’s assertion that this rule was not urged by appellee and was not briefed is patently incorrect. 2 See Calderon v. Atlas S. S. Co., .1898, 170 U.S. 272 , 18 S.Ct. 588 , 42 L.Ed. 1033 , and The Delaware, 1896, 161 U.S. 459 , 16 S.Ct. 516, 522-523 , 40 L.Ed. 771 .

In giving effect to the provisions of a bill of lading, the conditions and circumstances which the evidence proves were known to the parties and contemplated by them in making it, are to be taken into consideration. Pacific Coast Co. v. Yukon Independent Transp. Co., 9 Cir. 1907, 155 F. 29 ; W. R. Grace & Co. v. Frank Waterhouse & Co., Inc., 9 Cir. 1920, 264 F. 422 . We believe that here the parties understood that the obligation created between them required delivery to the wharf. No receipt was asked for nor obtained by the carrier from the lighterman. But when the goods left the lighters for customs, a receipt was then obtained by the carrier. Again, when the lighter sank, it was the carrier who was notified of the loss. (Answer, Interrog. 18(a) (1).) An inspection of the lighter was made, for the respondent, both prior to and immediately following the loading of the lighter, and after the breaking loose and first discharge “onto Quay 58.” (Ans. to Interrog. 16.)

Admittedly every carrier is responsible for the discharge of cargo from the vessel to a safe place. The Tangier, 1859, 23 How. 28 , 64 U.S. 28 , 16 L.Ed. 412 . The basic freight rate includes the cost of unloading. Under the facts of this case, in Alexandria, the carrier hired a contractor to do the unloading. That contractor in this case also operated the lighters. Its duty was to deliver to Egyptian Petroleum Storage Company as agent for the Egyptian customs authorities. The carrier paid for the stevedoring which put the cargo onto the lighters. The consignee was notified by the carrier, prior to arrival at Alexandria :

No such lighterage was provided by the consignee. The bill of lading provided (in paragraph 15):

Thus the carrier contracted under the assumption that there could be lighters used to effect delivery which would be operated or controlled by the carrier prior to delivery. In fact, no charge was made to the consignee until forty-eight hours after deposit by the ship’s tackle onto the lighters. Any such charge was “swallowed” in the freight rate charged by the carrier for delivery at Alexandria.

*45 Appellant urges that the forty-eight hour “no charge” is part of the tariff— Exhibit 6, and we accept that statement. The only part of Exhibit 6 printed in the transcript of record on appeal (p. 13) relates to carriage of goods from one quay “where the steamer has effected her discharge,” to other quays. That provision is not here applicable.

On the petition for rehearing appellant places great reliance on a case which (with many others) does not appear in its opening brief: W. R. Grace & Co. v. Frank Waterhouse & Co., Inc., supra. That involved the delivery of goods consigned to San Francisco, California, at Seattle, Washington, where they were delayed by a stevedore’s strike and damaged. The parties knew there had to be such a transshipment, because San Francisco was not a port of call for the vessel. Alexandria, Egypt, unlike San Francisco, was not “beyond a port of call.” Here there was no transshipment, no on-carriage — contemplated on required — beyond the port of call. The port of call here was Alexandria, to which, and no farther, carriage was contemplated by both parties to the contract.

Appellant cites some authority which suggests that the carrier was not invariably required to deliver to a wharf. Thus it is stated in The Tangier (Richardson v. Goddard), 1859, 23 How. 28 , 64 U.S. 28 , 16 L.Ed. 412 , that the carrier “is not bound to deliver at the warehouse of the consignee; it is the duty of the consignee to receive the goods out of the ship or on the wharf.” (Id. p. 39.) This dictum, however, does not tell us when, where or how the consignee may be required to “receive goods out of the ship.” Indeed the phrase may mean merely that the consignee might in some instances be required to take delivery directly off the ship when it has docked at a wharf. There is nothing in that opinion to indicate that a carrier under the general maritime law and in the absence of a special agreement could terminate his obligation by depositing the goods in lighters. The ease deals only with the requirements of a proper wharf delivery, and the language relied upon by appellant is pure obiter dictum. The maritime rule upon which this court and the court below relied is, we continue to believe, supported by strong authority which is not diminished by any authority or argument presented by appellant.

At this point appellant would again insist that his position has been misrepresented. His point is, as evidenced by the heading of his argument on page eight of the petition for rehearing, that the general maritime law recognized lighterage agreements and that therefore the common law did not require wharf delivery. Thus it is suggested, the “proper delivery” referred to in the Harter Act permits agreements which provide for delivery to lighters as well as delivery to a wharf.

But the Harter Act must be interpreted in light of the common law as it was, unmodified by the agreements which it permitted. As we have seen, the very purpose of the Harter Act was to prevent the carrier from avoiding its common law responsibilities by the device of securing “agreements” which included exculpatory clauses. To define the common law standards imposed by the Harter Act by reference to the contractual modifications which the common law permitted, would obviously destroy the Act. To say that the Harter Act permits parties to “agree” to lighter delivery because the common law permitted such “agreements,” is to perpetuate the evil which the Act sought to eradicate; viz. the cession by “contract” of rights which would otherwise exist.

This brings us to what is, in our opinion, appellant’s main point in its petition for rehearing. Appellant contends (at pp. 24-27 and 32-37) that Section 1 of the Harter Act does not deal with the scope of the carrier’s obligation to deliver. The Act, appellant asserts, does not determine whether, when or where the carrier must deliver the cargo. It only prevents the carrier from avoiding liability for loss arising from negligence in delivery, when the carrier has, in fact, undertaken to deliver the cargo.

*46 Acceptance of such a contention, we believe, weakens the Harter Act, and runs counter to its spirit and purpose. The Act provides that the carrier may not relieve itself of liability for loss due to negligence in the custody, care or proper delivery of cargo. As we have seen, proper delivery is accomplished when the cargo is placed on a fit wharf. In the instant case, the negligence which caused the loss occurred before such proper delivery' was accomplished. If, then, the bill of lading clause involved here is sufficient to save appellant harmless, the Act will have been circumvented. The carrier will. have inserted a “clause * * * whereby it [was] * * relieved from liability for loss * * * arising from negligence, fault, or failure in * * * custody, care, or proper delivery * *

We do not intend to say that appellant’s position is unreasonably assumed or entirely without merit. It is plausible for appellant to argue that since its contract with the shipper ended its transportation undertaking as soon as the cargo had been deposited in the lighters, it is not liable for any injury which occurred after such delivery to the lighters. The difficulty with this interpretation is that the Harter Act seems to contemplate a carrier liability which continues up until “proper delivery” has been effected, regardless of when the carrier’s obligation to transport the goods ceases. It is the office of the Act to nullify any bill of lading clauses which diminish or destroy this liability. Since the clauses in issue not only provide for lighterage, but also relieve appellant from liability for negligence during lighterage, they run counter to the provisions of the Harter Act. The clauses are, therefore, invalid insofar as they purport to relieve appellant of liability for losses due to negligence during lighterage.

As appellee contended and as this court pointed out in its' opinion, appellant’s position leaves no scope for application of the Harter Act. The Carriage of Goods by Sea Act in large measure supersedes the Harter Act, but the Harter Act is still applicable during the period following discharge and before delivery. If, however, “proper delivery” is completed as soon as the cargo leaves the ship’s tackle and is received by the lighterman, the Harter Act provisions can never become operative. Appellant asserts that this position is logically incorrect ; it maintains that discharge and delivery often occur “at the same instant, but [that] they involve different obligations and functions.” (Petition, p. 16.) Appellant points out, for example, that if the carrier were to deliver to a “wrong party,” it would be liable for “improper delivery.” On the other hand, if it delivered directly to the consignee, there would be a proper delivery immediately upon discharge without any time period for the Harter Act to operate.

Let us accept appellant’s contention that discharge and delivery often occur simultaneously and that the Harter Act then does not operate over a period of time but does have operative effect with respect to the function and responsibility of “delivery.” But even this limited scope for the Harter Act does not exist in the instant case, under appellant’s theory. It is appellant’s position that all of its obligations terminated when it transferred the cargo to the lighterman of its choice. If the lighterman thereafter does not deliver to the consignee, but wrongfully delivers to another party, that is none of appellant’s affair. Appellant has, thus, successfully contracted in such a manner as to avoid all liability for improper delivery. Not only is there no “time period” during which the Harter Act can operate, there is also no “function or responsibility” upon which the Act can operate. We think it clear that the purpose of the lighterage clauses in issue here is to attempt to avoid carrier responsibility for improper delivery. But the Harter Act makes unlawful all such attempts.

Appellant further attacks the court's opinion for holding’ the lighterage clauses “entirely void.” Appellant contends that the clauses are valid to the extent *47 that they are reasonable (Petition, pp. 20-24), and that even without the clauses, appellant had authority to arrange for necessary on-earriage (pp. 30-32).

This portion of appellant’s petition is based upon a misreading of the court’s opinion, for the court did not purport to hold the clauses invalid in their entirety. The court’s opinion did not hold, as appellant seems to believe, that a carrier cannot contract for authority to arrange for lightering of cargo at the shipper’s expense; it held only that a carrier cannot relieve itself of liability occurring during such lightering or at any time before proper delivery. To clarify this fact and make the opinion more certain, we suggest that the opinion should be amended by adding the words “the exculpatory provisions of” after the word “think” in line 42 on page 489 of 290 F.2d, and after the word “entirely” in line 19 on page 491 of the opinion. Such amendments are hereby made.

This court intimated that clauses relieving a carrier for liability during necessary lighterage, might, conceivably, be held valid under the Harter Act.But it did not decide the point. It pointed out that the clauses involved here were not limited to necessary on-carriage, and that since the exculpatory provisions, as written, are void under the Harter Act, they simply cannot be applied to a case where a conceivably valid exculpatory clause might apply. The Harter Act is clear on this: “Any * * * clauses of such import * * shall be null and void and of no effect.” Thus, the invalid exculpatory provisions in appellant’s bill of lading could be given no effect. This result is not at war with W. R. Grace & Co. v. Frank Waterhouse & Co., Inc., supra, or Tatsumma Kisen Kabushiki Kaisha v. Robert Dollar Co., 1929, 9 Cir., 31 F.2d 401 . Neither of these cases dealt with exculpatory clauses that were in conflict with the Harter Act, for neither case dealt with injury to cargo occurring before delivery.

In short, then, this court did not render the broad decision which appellant apparently thinks it rendered. The court did not say that a carrier is prohibited from securing lighterage agreements and it did not say that such agreements are unlawful or invalid. It said only that the exculpatory provisions of such agreements are void and can be given no effect whatsoever — -for such is the command of the Harter Act.

There is one other consideration of importance. Appellant points out that it would not be liable if the bill of lading had called for delivery to the Egyptian Stevedoring and Shipping Company, as on-carrier. Perhaps that is so and it raises an interesting point. Appellant agreed not to deliver to the stevedore, but to deliver to the port of Alexandria. By a broad clause of general applicability it reserved the right to discharge all of its responsibility to cargo by delivering to any on-carrier of its choice. The presence of this standardized clause in the contract does not represent an agreement between appellant and the shipper. It is simply a condition unilaterally imposed by the carrier upon the shipper; in the words of some scholars, it is an “adhesion contract,” viz. a contract “in which one party’s participation consists of his mere ‘adherence’.” (Ehrenzweig, Adhesion Contracts in the Conflict of Laws, 53 Colum.L.Rev. 1072, 1075; see also Dessler, Contracts of Adhesion, 43 Colum.L.Rev. 629.) We have already seen that the Harter Act was adopted to prevent the use of just such false agreements which make “freedom of contract” an illusion.

In the instant case, the carrier, by the use of such an adhesion contract, has said to the shipper, “you will authorize us to obtain lighterage whenever we deem it desirable.” This much, we have seen, does not conflict with the Harter Act and the court’s opinion does not tamper with this portion of the lighterage clauses. Then, the carrier says, “furthermore, we shall in no way be responsible for what happens to your goods during lighterage.” This is the language *48 which the court in its opinion held to be violative of the spirit if not the very letter of the Harter Act.

2. Failure to Show Carrier Negligence.

Appellant continues to maintain that the bill of lading clauses are sufficient to shift the burden of proof and to force the shipper to prove negligence. And such negligence, appellant claims, has not been shown. But appellant does not meet the argument advanced by the court, and the authority which he cites does not undermine the court’s position.

The Bellingham, 3 Cir. 1932, 57 F.2d 1015 , by dictum, as this court conceded, contains some support for appellant’s position. The case does not, however, command a decision in favor of appellant. The clause there in issue does not even purport to relieve the carrier from liability for negligence prior to delivery. Furthermore the cargo was, in fact, delivered to a fit and proper wharf and the only issue concerned damage occurring after such delivery. With respect to that damage the shipper had the burden of proving carrier negligence. The Harter Act was not involved nor could it have been since the carrier did not try to escape liability for damage occurring before wharf delivery.

The Monte Iciar, 3 Cir., 167 F.2d 334 , does not support appellant's position. The carrier did not attempt to exculpate itself from liability before delivery regardless of its own negligence. The bill of lading provision making the carrier “not responsible for leakage, breakage, or spigoting” (of wine barrels) did not purport to save the carrier harmless from negligently caused damage of the types enumerated. The bill of lading clauses involved in this case would parallel the clauses involved in Monte Iciar, if, for example, they purported to relieve appellant of responsibility “for any loss or damage to the goods * * (Emphasis added.) This clause, unlike the clause in The Monte Iciar, purports to avoid responsibility for negligence and therefore runs afoul of the Harter Act.

Clark v. Barnwell, 1851, 12 How. 272 , 53 U.S. 272 , 13 L.Ed. 985 , was decided long before the Harter Act was adopted and is, therefore, of no relevance here. Appellant has, then, failed to establish that an exculpatory provision — void under the Harter Act — nevertheless has sufficient vitality to shift the burden of proof. The court’s position on this point stands in its opinion unrefuted by logic or authority.

But the court pointed out that, in any event, there was affirmative proof of negligence, so that even if appellee had the burden of proof on this point, the trial court’s decision might still be sustained. In part, the court relied upon the infer ence to be drawn from the “unexplained” sinking of the lighter. Appellant now contends that no inference is permissible because the sinking is “explained,” but this assertion is in direct conflict with appellant’s previous contention that there is “no proof of the cause of the lighter breaking adrift or sinking.” (Reply Brief, p. 15.) The point need not be labored, however, since the burden of proof point is sufficient to sustain the original decision.

Appellant renews its argument that the only negligence charged amounted to “errors in management” for which it is not liable. If it seeks to establish such exemption from liability on the basis of its lighterage clauses, it is again met by the provisions of Section 1 of the Harter Act. Appellant claims, however, that Section 3 of the Act itself ( 46 U.S.C. § 192 ) provides such an exemption. Section 3 does save the carrier harmless for errors of navigation regarding the vessel, but it does not in terms apply to lighters, and its language (referring to the transportation of merchandise “to or from any port”) indicates that lighterage is not included. There is nothing to indicate that Section 3 is coextensive with Section 1 except appellant’s bald assertion that such is the case (Reply Brief, p. 17).

Furthermore, we agree with appellee that removing cargo from a quay and re *49 placing it into an unseaworthy lighter is not an error of management, but is negligence in the care of cargo. The reloading of the cargo may not have been negligently performed but it did constitute a negligent act.

Appellant agrees, even under its theory of the case, that the carrier had an obligation to see that the lighter was reasonably fit for the purpose for which it was intended — to have the cargo placed upon it.

The fact of sinking established a prima facie case of unseaworthiness. The district court found:

Furthermore, as the court pointed out, the exemption for errors of management extends only to errors of the ship’s master or crew and the inspection of the lighter was performed by the carrier’s agent (Ans. to Interrog. 35). Appellant now tells us that the inspector was not the carrier’s agent; but appellee in its answering brief had asserted that the inspector was appellant’s agent (p. 24), and appellant does not forthrightly deny this assertion in its reply brief. It asserted only that the master and crew had not “surrendered their management” with “an appeal to the owner to resume control himself.” (Reply Brief, p. 17.) An uncontroverted statement in an appellee’s brief may be taken as true. 5 C.J.S. Appeal and Error § 1345, p. 394. If appellant wanted to dispute the inspector’s agency status, it should have done so sooner in the case.

Thus the “error in management” argument must fall on either or both of the grounds originally relied upon.

3. The Real Party in Interest

In its opening brief, appellant argued that appellee had not proved itself to be the owner of the cargo. It contended that the only permissible inference was that title to the cargo passed at the time of shipment relying on California Civil Code, § 1739(4). But as pointed out by the court, applicability of § 1739(4) depends upon the terms of the contract which were not in evidence. Since the shipper was originally the owner of the cargo and since nothing was put in evidence to change that fact, it could be assumed (in fact we must assume)- — in support of the judgment — - that the shipper was still the owner of tht cargo. Appellant had not proved otherwise, and it certainly had not established any ground for invoking § 1739(4) in support of its position. The fact that appellee did not allege itself to be the owner of the cargo does not require this court to accept appellant’s argument on this issue. It is now too late for appellant to be offering affirmative evidence of a transfer of ownership at the time of shipment (Petition, p. 46).

Appellant’s failure to overcome the “ownership” theory makes it unnecessary to consider its long argument on the “trust” theory. This same failure also disposes of the fourth issue (appellee’s failure to give notice of its claim). Since appellee was the real party in interest, it was not required under the terms of the bill of lading to comply with the notice provision.

Upon modification of the original opinion as hereinabove specified, the judgment below is affirmed.

. Appellant’s petition for rehearing was eleven pages longer than its opening brief and closing brief combined.

With increasing frequency counsel seem to be confusing the function of a petition for rehearing with the rehearing itself, and the hearing of the petition with a'second appeal. The petition for rehearing filed in this case was a reargument of the appeal. In addition to the seventeen cases which were cited in appellant’s original opening brief, and the additional thirty in his reply brief, seventeen additional cases were cited on the petition for rehearing. See 44 Cal.L.Rev. 627, particularly p. 658.
