State, 59 Ala. 94. ,When bail is taken by commissioners it should be by bond, where the principal and sureties sign their names, as courts _ of commissioners are not courts of record, authorized to take acknowledg- ment of recognizances for future appearance before them or some court. g Courts of justices of the peace are not courts of record, authorized to take acknowledgment of recognizances for future appearance before them. U. S. v. Harden, 10 Fed. Rep. 805. And, as was said by the court in that case: "The powers and duties of the United States commissioners in criminal matters are not as extensive as those of justices of the peace, but are confined to those which they must necessarily exercise as exam- ining and committing magistrates in enforcing the criminal laws of the United States, and within this limit of jurisdiction they must conform as near as may be to the forms and mode of procedure required by law of justices of the peace." The commissioner holds no court; he acts as an arresting, examining, and committing magistrate. Ea: parte Perkins, 29 Fed. Rep. 909; U. S. v. Case, 8 Blatchf. 250; UZ S. v. Martin, 17 Fed. Rep. 150; IL S. v. Ambrose, 7 Fed. Rep. 554. For form of bail not in open court, see Code Ala. (1886) § 4420. It is required to be in writing, signed by the defendant and at least two suiiicient sureties, and approved by the ~ magistrate or oilicer taking the same; and this is all that is required. Under the statute of this state a sheriff has authority, and it is his duty, to discharge on bail persons charged by indictment with criminal offenses. In the case of a misdemeanor, no order of a judge or court is necessary, but the sheriff Hxes the amount of bail, and it is his duty to discharge the accused on sufficient bail being given. In the case of a felony, the court makes an order nxing the amount of bail required, and the sheriff has authority, and it is his duty, to discharge the defendant on his giving bail as required by such order; and a sheriff may discharge an accused on his giving suihcient bail when arrested on a warrant issued by a magistrate. See Code Ala. (1886,) §§ 4275, 4291, 4408, 4409; Ham- mom v. State. 59 Ala. 164; Ozeley v. State, Id. 94. A sheriff has no au- thority to take an acknowledgment. If, then, an acknowledgment is essential to bail, how is it that a sheriff can take bail without such acknowledgment? The acknowledgment, for the taking of which a. fee is prescribed, is an act having reference to conveyancing. It is the act of the grantor in going before a competent oiiicer and declaring the instru- ment to be his act and deed. — The oiiicer before whom this declaration is made is considered as taking the acknowledgment, and his certificate on the instrument that such a declaration has been made to him is also called an acknowledgment. 1 Bouv. Law. Diet. p. 50; Worcest. Diet.; Webst. Diet. Nothing of this kind is done or required to be done in taking bail. But there are certain instruments required to be acknowl- edged to entitle them to be recorded, and such instruments, to be valid in certain cases, must be recorded. Rev. St. §§ 4192, 4193. . Com- missioners of the circuit court are authorized to take such acknowledg- ments. Rev. St. § 1778. And for taking acknowledgments they are ontitled to receive a fee. Rev. St. § 847.
