No fees in criminal cases continued after the first term shall be allowed to witnesses on the part of the State until the 2nd day of the term in Hancock, Oxford, Franklin, Piscataquis and Aroostook; nor until the 3rd day in any other county, unless they were summoned at an earlier day. In all criminal cases, previous to the determination thereof, the court may allow such costs for justices, officers, aids, jurors and witnesses, as are provided by law, to be paid from the county treasury; but no court or judge shall allow any charge for aid or other expenses of the officer in serving a warrant, except his stated fees for service and travel unless, on his examination upon oath or on other evidence, they find such additional charges reasonable.
