MR. JUSTICE BRANDEIS delivered the opinion of the Court.

This libel was filed on January 25, 1918, by Armour Company against the steamship Fort Morgan in the federal District Court for eastern Louisiana. Recovery was sought for loss and damage to a shipment of 420 head of cattle received by the ship at Port Limon, Costa Rica, for delivery at Jacksonville, Florida. The charge was that unseaworthiness had caused her to list so heavily as to compel return to port and abandonment of the voyage, and that thereby half of the cattle were killed and the rest seriously injured. The libel alleged that the vessel was engaged as a common carrier between the ports named; that the cattle belonged to the libelant; that the bill of lading signed by the master was issued after delivery of the cattle on board. The copy of the bill of lading annexed to the complaint was signed "The Central American Cattle Co., Inc. By Thomas Johannesen, Master S.S. Fort Morgan." It recited: "Freight prepaid as per contract subject to Live Stock Agreement."

The owner made claim, impleaded the Cattle Company, and showed that the actual transaction was very different from that set forth in the libel. The shipment was an incident of a contract made October 3, 1917, by the Cattle Company with Armour Company to procure in Central American countries about 25,000 head of cattle and sell them to Armour Company; to assemble these from time to time at Port Limon for rest, inspection and loading; to charter and equip two steamers; and by means of these vessels to transport the cattle from Port Limon to Jacksonville and make delivery there. The contract provided further for attendance of an Armour representative at the inspection, grading, weighing and loading at Port Limon; that the vessels should carry only cattle for Armour Company; and that a supercargo representing them should have supervision over the care of the cattle during the voyage. It fixed the price per pound to be paid for different grades of cattle and the freight per head; and provided that payment of the purchase price and the freight be made at New Orleans upon receipt of cable advice from the Armour representative.

The Fort Morgan had been chartered by the Cattle Company. She listed when she left Port Limon and had to return to port and abandon the voyage. But she had been seaworthy when delivered to the Cattle Company as charterer and was thereafter. The loss is claimed to have resulted from the abuse of the ship by the Cattle Company, under the supervision of Armour Company's supercargo. The charter party, entitled a "Time Charter — West India Fruit Trade," provided the privilege of and facilities for erecting a light fruit deck to carry a load of fruit. At Port Limon she was, without the consent of the owner, converted into a cattle ship. On the deck, authorized as a fruit deck, cattle pens were constructed and the heavy cattle were loaded. Freight had not been paid when the bill of lading issued; nor was it ever paid. No payment for the cattle was ever made under the contract. After the voyage was abandoned, the Cattle Company brought suit against the Armours at New Orleans. Later the parties entered into an agreement to settle their differences out of court. The compromise provided for a new trade arrangement; for holding on joint account the surviving 200 head of injured cattle then at Port Limon; and for the payment by the Armours of $19,000 upon performance by the Cattle Company of conditions set forth in the new agreement. Seven days later this libel was filed. There was no reservation of right under the bill of lading, or of any rights against the ship. Through investigations incident to the defense the owner first learned the facts.

The District Court dismissed the libel with costs, finding the facts substantially as stated above. The libelant had insisted that the ship was liable because the master had signed the bill of lading; and that, having been unseaworthy, she would have been liable even without such signing, since the master had received the cattle on board. The court held, in an unpublished opinion, that while the vessel would ordinarily be liable for any damage resulting from unseaworthiness, there could be no recovery in this case, because the unseaworthiness had resulted from the conversion of the vessel into a cattle ship; that this conversion involved a change in the charter party which the master was without authority to make, Gracie v. Palmer, 8 Wheat. 605, 639; that the owner could not be subjected thereby to liability; that, morever, under the terms of the charter party, the owner would be entitled to be indemnified by the charterers for any judgment in favor of Armour Company; that the compromise made by Armour Company with knowledge that the vessel was chartered barred this suit; and that, in any event, recovery could not be had on the allegations of the libel.

The Circuit Court of Appeals affirmed the judgment of the District Court, 297 F. 813. It held that the bill of lading, although signed by the master, did not indicate a purpose to bind the ship; that this fact, taken in connection with the pre-existing contract, required the conclusion that the shipper's contract of affreightment was only with the Cattle Company; and that, under these circumstances, the ship could not be held. That court did not pass upon or discuss the grounds of decision adopted by the District Court. Nor did it refer to the well-established rule that the ship is ordinarily liable to the shipper upon an implied warranty of seaworthiness although a bill of lading signed by the charterer is given. See The Carib Prince, 170 U.S. 655, 660; The Esrom, 272 F. 266. A petition for a writ of certiorari sought on the ground that this basis of liability had been ignored was granted. 266 U.S. 597. The respondent had not opposed the granting of the writ; and it did not attempt here, in the brief and argument on the merits, to support the ground of decision stated by the Court of Appeals. It insisted that the judgment should be affirmed substantially for the reasons stated by the District Court.

The suit is brought to enforce the lien or privilege against the vessel which the maritime law gives as security for the contract of affreightment. The contract contained in the bill of lading was that of the Cattle Company. The bill of lading, which was signed by that company, is not to be treated as an isolated transaction. It referred to a contract between the parties. It was in fact given in part performance of the obligations assumed by the Cattle Company by the original contract to purchase the cattle, assemble them at Port Limon, sell them to the Armours, and transport them to Jacksonville. The compromise agreement substituted new rights and obligations for the obligations assumed by, and the liabilities incurred under, the original contract. Thereby, it discharged the primary liabilities of the Cattle Company to the Armours under both the original contract and the bill of lading to carry safely the cattle from Port Limon to Jacksonville. The discharge of this primary liability necessarily discharged also the liability of the ship as surety for the charterers' obligation set forth in the bill of lading. For this reason, and also because of the facts found by the District Court concerning the unauthorized conversion of the vessel into a cattle ship with the participation of the Armours, the libel was properly dismissed.

An objection to the jurisdiction taken by the owner both here and below must be noticed. On the face of the libel there was confessedly admiralty jurisdiction. The contention is that the facts developed later disclosed a transaction not wholly maritime, and that, for this reason; the libel should have been dismissed under the rule declared in Grant v. Poillon, 20 How. 162, 168-9. The District Court stated that it was "inclined to agree with the contention," but apparently did not pass definitely upon the matter. The Circuit Court of Appeals did not mention the objection. The decree entered was a general one dismissing the libel, as on the merits. If there was no jurisdiction, the decree should have recited that ground of dismissal, so as to be without prejudice.

The case is not of that class where the existence of jurisdiction is conclusively determined by the first pleading of him who institutes the suit. Compare Clarke v. Mathewson, 12 Pet. 164; Boston Montana Mining Co. v. Montana Ore Purchasing Co., 188 U.S. 632. Jurisdiction in admiralty cannot be effectively acquired by concealing for a time the facts which establish that it does not exist. Compare Lambert Run Coal Co. v. Baltimore Ohio R.R. Co., 258 U.S. 377, 382. We must, therefore, consider whether the facts developed after the filing of the libel preclude the exercise of admiralty jurisdiction. The bill of lading and the charter party are both maritime contracts and, hence, enforceable in a court of admiralty. Morewood v. Enequist, 23 How. 491; The Eddy, 5 Wall. 481, 494. The original contract to purchase, assemble, and sell the cattle, to charter vessels and therein transport the cattle to Jacksonville, and the agreement of compromise, are not maritime contracts. The Richard Winslow, 71 F. 426; The Ada, 250 F. 194. Both the original contract and the compromise agreement are referred to in order to establish the fact that the obligation for which the ship was surety had been discharged. The original contract was referred to, also, to explain the relation of the shipper named in the bill of lading to the charterer and in order to establish that by reason of their co-operation in converting the vessel into a cattle ship there was no liability. Such uses of non-maritime contracts to establish the absence of a valid maritime claim, or a defence as distinguished from a counterclaim (see The Eclipse, 135 U.S. 599, 609), do not deprive the admiralty court of jurisdiction. No party to this suit sought to enforce any right under either of the non-maritime contracts.

Affirmed.
