The jury is impaneled as follows: The justice directs the sheriff or constable to make a list of twenty-four inhabitants of the county qualified to serve as jurors in the district court, or of eighteen if the jury is to consist of six persons.

Each party may then strike out six of the names.

The justice then issues a venire [Footnote: For forms, see page 280.] to the sheriff or a constable, directing him to summon the persons whose names remain on the list to act as jurors.
Witnesses .-- If any of the witnesses should be unwilling to come, the justice issues a subpoena [Footnote: For forms, see page 279.] commanding them to appear.

The subpoena may contain any number of names and may be served by any one.

It is "served" by reading it to the person named therein, or by delivering a copy of it to him.
