Where the master performs seamen's duties in addition to his own it has been held he is not entitled to a lien for compensation for such work, but in some more recent cases such liens have been allowed. There is a substantial conflict of authority on this point.

7. Relations to Cargo.—

He has no authority to alter a charter party, nor to sign a bill of lading for goods not shipped or containing a misdescription of the cargo. He must not mis-date a bill of lading nor issue one contrary to the terms of the charter. He must see that the cargo is well and sufficiently stored in accordance with law and that the ship is not overladen. The law contemplates that the master himself must be a competent stevedore. Thus in the leading case of the Niagara, 21 How. 7, it is said:

He (the master) must take care to stow and arrange the cargo, so that the different goods may not be injured by each other, or by the motion of the vessel, or its leakage; unless, by agreement, this duty is to be performed by persons employed by the shipper. In the absence of any special agreement, his duty extends to all that relates to the lading, as well as the transportation and delivery of the goods; and for the faithful performance of those duties the ship is liable, as well as the master and owners.

Even where the shipper employs the stevedores, it remains the right and duty of the master to control them if they are endangering the ship's safety. Thus in the Elton, 83 Fed. 519, where the charter party provided that the stevedore was to be employed and paid by the contractor and was to load the steamer under the master's direction, it was said:

At no time does the master lose his proper place in the control of his ship and everything connected therewith. The stevedore is not an independent contractor, doing the work, which, when completed, is to be turned over to the master for his approval or disapproval; but he must load the steamer at all times under the direction and subject to the control of the master.

During the voyage and until the goods are delivered he stands as bailee and has a high degree of responsibility for their safekeeping. He must pursue the voyage without deviation or delay except for the purpose of saving life. He must be watchful to protect the cargo, in whole and in parts, as against deterioration and damage. Safe custody is as much a part of his duty as safe carriage and delivery. In case of emergency and necessity he becomes as much an agent of the cargo as of the owner of the ship and may sacrifice a part for the safety of the whole venture, or mortgage or sell the same, or tranship it. In the event of peril the duty and power devolve upon the master to determine whether a jettison be necessary. As the court said in Lawrence v. Minturn, 17 How. (U. S.) 100:

If he was a competent master, if an emergency actually existed calling for a decision, whether to make a jettison of a part of the cargo; if he appears to have arrived at his decision with due deliberation, by a fair exercise of his skill, and discretion, with no unreasonable timidity, and with an honest intent to do his duty, the jettison is lawful. It will be deemed to have been necessary for the common safety, because the person to whom the law has entrusted authority to decide upon and make it has duly exercised that authority.

But though the master may jettison cargo to lighten a ship in peril, he may not, for that purpose, give cargo away. It is not his to give, and if he attempts to do so, the donee takes no title and is liable for the conversion of it as for embezzlement (The Albany, 44 Fed. 431).

The duties and powers of masters of vessels in regard to cargo, as they develop out of the exigencies of navigation and the varied situation abroad, are much broader than those of the agents of carriers by land, because the circumstances are so very different. Such a master has authority to do whatever is really necessary to preserve the interests of an absent owner or consignees. He is bound to the exercise of diligence and good faith to give the owner or consignee timely information; and to follow instructions if they can be obtained. If his possession of the goods is interfered with by legal process or seizure, he must give notice, if possible, and in the meantime take all proper steps to protect or recover the goods. He may be bound to take legal proceedings or answer for the damages caused by his failure to do so.
