But we are also of opinion that even if the contract of a seaman could be considered within the letter of the Thirteenth Amendment, it is not, within its spirit, a case of involuntary servitude. The law is perfectly well settled that the first ten amendments to the Constitution, commonly known as the "Bill of Rights," were not intended to lay down any novel principles of government, but simply to embody certain guaranties and immunities which we had inherited from our English ancestors, and which had, from time immemorial, been subject to certain well recognized exceptions arising from the necessities of the case. In incorporating these principles into the fundamental law, there was no intention of disregarding the exceptions, which continued to be recognized as if they had been formally expressed. Thus, the freedom of speech and of the press (Art.

to keep and bear arms (Art. II) is not infringed by laws prohibiting the carrying of concealed weapons; the provision that no person shall be twice put in jeopardy (Art. V) does not prevent a second trial if upon the first trial the jury failed to agree or if the verdict was set aside upon the defendant's motion, United States v. Ball, 163 U. S. 662, 163 U. S. 627, nor does the provision of the same article that no one shall be a witness against himself impair his obligation to testify if a prosecution against him be barred by the lapse of time, a pardon, or by statutory enactment, Brown v. Walker, 161 U. S. 591, and cases cited. Nor does the provision that an accused person shall be confronted with the witnesses against him prevent the admission of dying declarations, or the depositions of witnesses who have died since the former trial.
