Service by publication generally

On affidavit that a defendant is a foreign corporation for which no statutory attorney-in-fact, officer, director or agent is found in this state upon whom service may be had, or is not a resident of this state, or that diligence has been used by or on behalf of the plaintiff to ascertain in what county he is, without effect, or that process, directed to the officer of the county in which he resides or is, has twice been delivered to such officer more than ten days before the return day, and been returned without being executed, an order of publication may be entered against such defendant. And in any suit in equity, where the bill states that there are or may be persons interested in the subject to be divided or disposed of, whose names are unknown, and makes such persons defendants by the general description of parties unknown, on affidavit of the fact that such parties are unknown, an order of publication may be entered against such unknown parties. Any order of publication under this section may be entered either in court or by the clerk at any time. In a proceeding by petition, there may be an order of publication in like manner as in a suit in equity.
