The cargo, except for the collection of the freight due, cannot be held for the faults of the ship. There being no lien beyond freight due, no proceeding in rem lies against the cargo for damages by collision, if the freight be paid, whether the cargo belongs to the owner of the offending vessel or not; and, if arrested, the cargo must be released upon the payment of the freight due.

A maritime lien, being essentially a remedy against the vessel, may attach even in a case in which the owners are not personally responsible; as for instance, where a state pilot, in charge of a ship under a state statute which renders his employment compulsory, negligently brought the ship into collision, she was subjected to a lien for the damage done, although the pilot was in no sense the agent of the owners, and no personal liability rested upon them. The China, 7 Wall. 53.

The lien attaches only by virtue of contracts or torts which are wholly maritime in their nature. It is frequently difficult to determine the nature of a contract or tort. Thus persons digging ice and snow from around a vessel on a beach, and about to be launched did not acquire a maritime lien because the service was performed on shore. Whereas persons who floated a vessel which had been carried far ashore were held to have performed a maritime service and to be entitled to a lien. In a case in which a vessel communicated fire to a wharf to which she was made fast, it was held that the tort was not maritime, whereas, had she been in the stream and had communicated fire to another vessel in the stream, the tort would have been maritime and would have given rise to a maritime lien (Hough v. Trans. Co., 3 Wall. 20). Conversely a tort having its inception on land and completed on shipboard will give rise to a lien. As for example where a man working on board ship was injured by a piece of lumber thrown through a chute by a man working on a wharf. (Herman v. Mill Co., 69 Fed. 646).

A lien arises in favor of the owners or temporary owners of a vessel upon cargo actually on board for unpaid freight and for demurrage. This is the only case in which possession of the security is essential to the existence of a maritime lien. If the cargo is removed from the ship the maritime lien is lost. In this class of cases suit to enforce the lien should be instituted before the cargo is discharged.

2. Essential Value.—

The essential value of these liens lies in the right they give to have the ship arrested and sold by a court of admiralty for their satisfaction, and in the speed and security with which the remedy can be applied. The vessel is arrested immediately upon the filing of the libel, before the liability is proven or the case tried, and may not leave port without giving bond to secure the claim (see Chapter XVII, Admiralty Remedies).

3. Independent of Notice or Possession.—

They do not depend upon notice or recording or possession and do not in any way resemble a mortgage. They are, in fact, an actual property in the ship, created as soon as the service is rendered or the wrong suffered (Yankee Blade, 19 How. 82).

4. Secret.—

As these liens do not depend upon notice or record, they are essentially secret in their nature and even purchase of the ship, in good faith and for value, will not be protected against them (The Marjorie, 151 Fed. 183).
