When such summons is served by leaving a copy thereof at the usual place of abode of the grantor or lessor, and it does not appear that actual notice was given, the judge shall continue the hearing from time to time, not exceeding 90 days, and direct that actual notice be given if the party resides in the state. When such notice cannot be given, the judge shall proceed in the examination as provided in section 374 of this title, and his or her certificate of the execution of the deed shall have the same effect as therein provided.
