[27] "Where the sacrifice, while for the general benefit of the whole adventure, was also for the particular benefit of the cargo, it was not a subject of general average" (The Mary, 1 Sprague 19).
[28] Expenses voluntarily and successfully incurred, or the necessary consequences of resolution voluntarily and successfully taken, by a person in charge of a sea adventure, for the safety of life, ship and cargo, under the pressure of a danger of total loss or destruction imminent and common to them, give, the ship being saved, a claim to general average contribution (Abbott on Shipping, 537, note).
[29] Thus where a tug abandoned her tow in order to save the tug; the owners of the tow were not entitled to general average contribution because it was not a part of the ship or cargo.
[30] Probably the earliest recorded case is that mentioned in Jonah 1, where cargo was jettisoned to lighten a ship in peril on a voyage from Joppa to Tarshish. The elements of general average were present, though it does not appear that an adjustment was made.
CHAPTER XIV
CRIMES COMMITTED AT SEA
1. Definition.—
A crime consists in the violation of a public law either forbidding or commanding an act to be done. One act may constitute several crimes against different jurisdictions, as against a State and the United States and a foreign country. Crimes are classified as treason, felonies and misdemeanors. Treason against the United States consists only in levying war against them, or in adhering to their enemies, giving them aid and comfort. Felonies are crimes punishable by death or imprisonment in a state prison; all other crimes are misdemeanors.
Crimes committed at sea are those accomplished upon the high seas or within the jurisdiction of the admiralty, which extends over all navigable waters. Such crimes are punishable by the United States so far as Congress legislates on the subject and otherwise by the particular sovereignty within whose jurisdiction the offense is committed.
