This is an appeal from a decree of the Circuit Court of the United States for the eastern district of Louisiana.

The libel alleges that the appellants shipped on board the brig Ann Elizabeth, at Wilmington, in the State of Delaware, a large quantity of gunpowder, to be carried to New Orleans, in the State of Louisiana; and that, on the shipment thereof, bills of lading, in the usual form, were signed by the master of the brig; that, according to the invoices of the merchandise specified in the bills of lading, its value was $7,233.75; that, on the arrival of the brig at New Orleans, the libellants required the delivery of the merchandise thus shipped, but they received only a part thereof; and that the part not delivered consisted of 1,646 packages, which, according to the same invoice valuation, amounted to the sum of $5,936.54.

Dupont v. Vance/Opinion of the Court

The libel further alleges that no part of that sum has been paid to the libellants; and it prays process against the brig, and a decree for the damages thus demanded, and for such other relief as shall to law and justice appertain.

Dupont v. Vance/Opinion of the Court

The master of the brig, intervening for his own interest and that of his part-owners, admits that the shipment of goods was made, as alleged in the libel; but propounds that, in the course of the voyage, it became necessary, for the safety of all concerned, through the perils and dangers of the seas, to make a jettison of that part of the libellant's goods which were shipped and not delivered.

Dupont v. Vance/Opinion of the Court

The first question is, whether the claimant has shown, in support of his defensive allegation, that the jettison was occasioned by a peril of the sea. If it was, then the carrier is exonerated from the delivery of the merchandise, and has only to respond for that part of its value which is his just contributory share towards indemnity for the common loss by the jettison. A jettison, the necessity for which was occasioned solely by a peril of the sea, is a loss by a peril of the sea, and within the exception contained in the bill of lading.

But, if the unseaworthiness of the vessel, at the time of sailing on the voyage, caused, or contributed to produce, the necessity for the jettison, the loss is not within the exception of perils of the seas.

That there was such a necessity for this jettison as justified the master in making it, we think, is proved. In the case of Lawrence v. Minturn, (17 How., 109,) this court had occasion to consider the extent of the authority of the master to make a jettison. We then held, that '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 intrusted authority to decide upon and make it, has duly exercised that authority.' We find the case at bar is within this rule. We do not detail the evidence, because the authority of the master to make the jettison has not been seriously controverted.

This part of the case turns upon the other inquiry, whether the vessel was unseaworthy for the voyage when it was begun.

It is the hull of the vessel which is alleged to have been unseaworthy. To constitute seaworthiness of the hull of a vessel in respect to cargo, the hull must be so tight, stanch, and strong, as to be competent to resist all ordinary action of the sea, and to prosecute and complete the voyage without damage to the cargo under deck.

If a vessel, during the voyage, has leaked so much as to injure the cargo, or render a jettison of it necessary, one mode of testing seaworthiness is, to ascertain what defects, occasioning leakage, were found in the vessel at the end of the voyage; and then to inquire which of those defects are attributable to perils of the seas, encountered during the voyage, and which, if any, existed when it was begun; and, if any of the latter be found, the remaining inquiry is, whether they were such as to render the vessel incompetent to resist the ordinary attacks of the sea, in the course of the particular voyage, without damage or loss of cargo.

This vessel, on her arrival at New Orleans, was taken into dock, and examined. She was found to be a new vessel, and that she had been strained. A but, about midships, at or near the third or fourth streak, was started. The hood-ends forward were also strained, and, on trial, it was found they would take about a thread of oakum.
