after stating the case, delivered the opinion of the court.
Thе indictment in this case is in form sufficiently full and specific in its averments to embrace the offence prescribed by the statute, and yet the defendant charged is not within its provisions. He is designated as a clerk in the office of the cоllector of customs, and is thus shown not to be charged by an act of Congress with the safe-keeping of the public mоneys, contrary to the averments of the indictment. The courts of the United States are presumed to know the general statutes of Congress, and any averment in an indictment inconsistent with a provision of a statute of that character, must mecessa-rily fail, the statute negativing the averment. No clerk of a collector of customs is, by § 3639 of the Bevised Statutes, charged with the safe-keeping of the public moneys. That section requires the treasurer of the Unitеd States, assistant treasurers, and those performing the duties of assistant treasurer, collectors of customs, surveyors of customs, acting also as collectors, receivers of public moneys at the several land officеs, postmasters, and all public officers of whatsoever character, to keep safely all public money collected by them, or otherwise at any time placed in their possession and custody, till the same is ordered by the proper department or officer of the government to be transferred or paid out. They arе also required to perform all other duties as fiscal agents of the government which may be imposed by law, or by any regulation of the Treasury Department made in conformity to law. A clerk of the collector is not an officer of the United States within the provisions of this section; and it
*532
is only to persons of that rank that the term public officer, as there used, applies. . An officer of the United States can only be appointed by the President, by and with the advice and consent of the Senate, or by a court of law, or the head of a department. A person in thе service of the government who does not derive his position from one of these sources is not an officеr of the United-States in the sense of the Constitution.' This subject was considered and determined in
United States
v.
Germaine,
The number of clerks the colleсtor may employ may be limited by the Secretary of the Treasury, but their appointment is not .made by the Secretаry, nor is his approval thereof required. The duties they perform are as varied as the infinite details of the business of the collector’s office, each taking upon himself such as are assigned to him by the collector. The оfficers specially designated in § 3639 are all charged by some act of Congress with duties connected with the cоllection, disbursement, or keeping of the public moneys, or to perform other duties as fiscal agents of the gоvernment. A clerk of a collector holding his position at the will of the latter, discharging only such duties as may be assigned to him by that officer, comes neither within the letter nor the purview of the statute. And we are referred to no other act of Congress bearing on the subject, making a clerk of the collector a fiscal agent of the govеrnmetit, or bringing him within the class of persons charged with the safe-keeping of any public moneys.
The case of
United States
v.
Hartwell,
Our conclusion,' therefore, is that § 3639 of the Revised Statutes does not apply to clerks of the collector, and that such clerks are not appointed by the head of any depаrtment within the meaning of the constitutional provision.
It follows that our cmswers to the second and third questions certified to us must he in the negative- An cmswer to the first question is therefore immaterial.
