“ Crimes committed against the laws of the United States out of the limits of a State are not local, but may be tried at such place as Congress shall designate by law, but are local if committed within the State. They must then be tried in the district in which the offence was committed. (15 How., 488, 6th amendment of the Constitution of U.S.)

“ There is a proviso which declares that nothing in the section shall be construed to deprive any particular State of its jurisdiction over the offence, when committed within the body of a county, or authorize the courts of the United States to try such offenders after conviction or acquittance for the same offence in a State court. ”

Leete, the master of the vessel, putting him in bodily fear, and did feloniously, &c., seize, take, and carry away thirty pieces of gold coin, &c., of the goods and effects of the said master, contrary to the form of the statute, &c. ”
