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.
