ever the panel of the jury is exhausted the court order that the jurors 
wanted shall be selected from among the bystanders which order bears the

Sec. 29, that When from challenges, or otherwise, there shall not be a jury 
to determine any civil or criminal cause, the marshal or his deputy shall, 
by order of the court where such defect of jurors shall happen, return 
jurymen de talibus circumstantibus sufficient to complete the panel; and 
when the marshal or his deputy are disqualified as aforesaid, jurors may be 
returned by such disinterested persons as the court shall appoint. See 2
