The Eighteenth Amendment to the Federal Constitution prohibits "the manufacture, sale, or transportation of intoxicating liquors within, the importation thereof into, or the exportation thereof from the United States and all territory subject to the jurisdiction thereof for beverage purposes." 40 Stat. io5O, 1941. In the National Prohibition Cases. 253 U. S. 350, 386, the amendment was said to be operative "throughout the entire territorial limits of the United States." As originally enacted, the National Prohibition Act did not in terms define its territorial field, but a supplemental provision afterwards enacted declares that the act "shall apply not only to the United States but to all territory subject to its jurisdiction." 42 Stat. 222. In other words, its field expressly coincides with that of the Amendment.
