Unrrsn sums v. rom). r27 fore, alwaystbeen vague and indefinite. A mere intention, to commit a crime does not render a person amenable to law. It must be manifested by some accompanying act of willful wrong or culpable negligence to make it criminal in law. A man’s motives and intentions can only be properly inferred from the means which he uses, and the acts which he does. An attempt imports something done towards the accomplishment of a conceived purpose, without success. An attempt to commit a crime is- an incomplete effort made by some act intermediate to a criminal in- tention and a consummated crime. The intention of the actor can alone be clearly ascertained by the movements which he has made to com- plete his design. The criminal nature of an offense is a conclusion of law derived from the facts and circumstances of the case. In an at- tempt to commit a crime, the acts and words of a wrong-doer are, there- fore, essential ingredients to constitute an offense, and show the purpose he had in view. The wordV"attempt" is generally used in the law in describing the offense of an unsuccessful effort to commit a crime; but it has no technical meaning importing sufiicient legal certainty as to the manner, the means used, and the intention of the wrong-doer. Its force and effect in an indictment was dependent upon a statement of the facts and circumstances that accompanied and constituted the illegal eiiort al- leged. An assault is an attempt to do some personal violence to another, and the word "assault" has acquired a technical signification that im- ports an allegation of intentional violence and illegality. This definite technical meaning of the word makes it unnecessary, in an indictment for an assault with intent to commit a crime, to describe such offense with the same particularity that would be required in an indictment for the commission of the crime itself. In the indictment now before us, for an attempt to rescue spirituous liquors duly seized by the otiicers of the law, if it had been alleged that such attempt was made by an assault upon such officers while in the discharge of their official duty, such allegation wouldlhave been sufficiently definite, and would have been supported by the evidence offered on the trial. In 2 Whart. Crim. Law, § 2686, there is a definition of an indictable attempt to commit a crime, and it is as full and accurate as can, prob- ably, be made; but Mr. Wharton says, in a subsequent section, (2703,) "Attempt is a term peculiarly indefinite." . The indefinite nature of the offense, at common law, of an attempt to commit a crime, has induced the enactment of many statutes in England and this country, setting forth, in express terms, what acts shall con- stitute an attempt to commit the crimes referred to in such statutes. In a case not thus specifically defined, the offense of an attempt to commit a crime, although declared, in general terms, in a statute as a crime, re- mains as at common law, and its nature is dependent upon its peculiar circumstances, and they must be distinctly alleged in an indictment. The overt acts or words that indicate the intention of the alleged wrong- doer must be considered by the jury, upon the evidence, in determining the essential question—whethe1· such intention was criminal. Every- thing necessary to be proved must be alleged.
