Rents reserved, pay- able in work, grain, and the like. Such rents were called black mail (reditus nigri) in distinction from white rents (blanche firmes), which were rents paid in silver. A yearly payment made for security and protection to those bands of marauders who infested the borders of England and Scotland about the middle of the sixteenth century and laid the inhabitants under contribution. Hume, Hist. Eng. vol. i. 473; vol. ii. App. No. 8; Cowel. In common parlance, the term is equiva- lent to, and synonymous with, extortion- the exaction of money, either for the per- formance of a duty, the prevention of an injury, or the exercise of an influence. It supposes the service to be unlawful, and the payment involuntary. Not unfrequently it is extorted by threats, or by operating upon the fears or the credulity, or by prom- ises to conceal, or offers to expose the weaknesses, the follies, or the crimes of the victim. 17 Abb. Pr. 226. Thareats by defendant to accuse another of crime, with intent, himself, to commit the crime of extortion, accompanied by success in obtaining money from that other. That such other person was endeavor- ing to induce defendant to receive money, for the purpose of accusing him of extortion, and so could not have been moved by fear, will not prevent his conviction for an at- tempt at extortion; 144 N. Y. 119; under an act declaring it a crime to threaten a person with a criminal prosecution, for the purpose of extorting money, it is im- material that the person making the threats believed that the person threatened had committed the crime: 75 Hun 26; where threate of prosecution for perjury were made maliciously and with intent to compel the one threatened to do an act against his will, the offence is complete; and it is immaterial whether the one threat- ened was guilty of perjury; 61 N. W. R (Mich.) 18. In a prosecution under an act providing for the punishment of one who, for the purposes of extortion, sends a letter expressing or implying, or adapted to im- ply, any threat, and the letter threatens to make a charge against the person to whom it is sent, the truth or falsity of the charge is immaterial; 95 Cal: 640; the act making it an offence to accuse one of crime "with intent to extort or gain any chattel, money, or valuable security, or any pecuniary ad- vantage whatsoever," does not cover the case of an owner who demands a reason- able compensation for property criminally destroyed, and accompanies his demand with a threat to accuse the defendant of the crime, and, where the owner of property so destroyed is indicted for extortion, it is error to charge that it is immaterial whether the accusation made by him was true or false; 47 Ohio St. 556. A charge of soliciting sexual intercourse with the wife of another is a charge of immoral conduct, which, if true, would tend to disgrace one and sub- ject him to the contempt of society, and threatening to make such charge is black mail; 24 N. E. R. (Ind.) 342. A conviction on indictment under Iowa Code § 3871, relating to the offence of making malicious threats with intent to extort money, cannot be sustained by evi- dence that defendant, a constable, had a search warrant for the premises of the complaining witnesses; that he notified them of the fact, and signified his willing- ness, for a bribe, to refrain from making search, that the witnesses accordingly gave him money, and that he assured them the matter would be dropped; 76 Ia. 189. On a trial for maliciously threatening to accuse another of burning a building, with intent to extort money, evidence of the truth of the charge is inadmissible on the question of malice or of intent, or to impeach the prosecuting witness; 18 N. E. R. (Mass.) 577.
