It shall be lawful for the county board of any county to enter an order upon their records, allowing to any person who shall have aided or assisted in the pursuit or arrest of any person suspected or accused of any felony, or other high crime, committed in their county, such reasonable sum as said county board shall deem just, to defray the expenses of the person in aiding or assisting in the pursuit or arrest of such offender in making such pursuit or arrest; which sum so allowed shall be paid out of the county treasury in the same manner that other county expenses are paid.
