3. The Libel.—
No process or writ can be issued by a court of admiralty before a libel is filed in the clerk's office. A libel is the statement of the party's claim and the relief or remedy which he desires. It states the nature of the cause, for example, that it is of contract, or of tort or damage, or salvage, as the case may be; the ship, or property, against which the claim is made and that it is, or soon will be, within the district; the facts upon which the claim is based; and the relief sought. For convenience, it should be expressed in concise paragraphs or articles, and, of course, must state a case within the jurisdiction of the court.
