"SEC. 8. _And be it further enacted_, That the marshals, their deputies, and the clerks of the said District and Territorial Courts, shall be paid, for their services, the like fees as may be allowed to them for similar services in other cases; and where such services are rendered exclusively in the arrest, custody, and delivery of the fugitive to the claimant, his or her agent or attorney, or where such supposed fugitive may be discharged out of custody for the want of sufficient proof as aforesaid, then such fees are to be paid in the whole by such claimant, his agent or attorney; and in all cases where the proceedings are before a commissioner, he shall be entitled to a fee of ten dollars in full for his services in each case, upon the delivery of the said certificate to the claimant, his or her agent or attorney; or a fee of five dollars in cases where the proof shall not, in the opinion of such commissioner, warrant such certificate and delivery, inclusive of all services incident to such arrest and examination, to be paid, in either case, by the claimant, his or her agent or attorney. The person or persons authorized to execute the process to be issued by such commissioners for the arrest and detention of fugitives from service or labor as aforesaid, shall also be entitled to a fee of five dollars each for each person he or they may arrest and take before any such commissioner as aforesaid, at the instance and request of such claimant, with such other fees as may be deemed reasonable by such commissioner for such other additional services as may be necessarily performed by him or them; such as attending at the examination, keeping the fugitive in custody, and providing him with food and lodging during his detention, and until the final determination of such commissioner; and, in general, for performing such other duties as may be required by such claimant, his or her attorney or agent, or commissioner in the premises, such fees to be made up in conformity with the fees usually charged by the officers of the courts of justice within the proper district or county, as near as may be practicable, and paid by such claimants, their agents or attorneys, whether such supposed fugitives from service or labor be ordered to be delivered to such claimants by the final determination of such commissioners or not.
