Any point, space, or division of time. “The word ‘period’ has its etymo- logical meaning, but it also has a distinctive signification, according to the subject with which it may be used in connection. It may mean auy portion of complete time, from a thousand years or less to the period of a day; and when used to designate au act to be doue or to be begun, though its completion may take an uncertain time, as, for instance, the act of exportation, it must mean the day on which the exportation commences, or it would be au unmeaning and useless word in ita connection iu the statute.” Sampson v. Peas- lee, 20 How. 579, 15 L. Ed. 1022.
