Such sheriff shall serve and return it in the same manner in all respects as though it had originated in his county, except that the return thereof shall be made to the sheriff of the originating county on or before June 1 next following its issuance. The sheriff actually serving such warrant shall be allowed the fees and mileage allowed by section 77-1720.
