Punishment because of the fraudulent purpose is no new thing. As said by Mr. Justice Brown, in Evans v. U. S., 153 U.S. 584, 592 , 14 S. Sup. Ct. 934: 'If a person buy goods on credit in good faith, knowing that he is unable to pay for them at the time, but believing that he will be able to pay for them at the maturity of the bill, he is guilty of no offense, even if he be disappointed in making such payment. But if he purchases them knowing that he will not be able to pay for them, and with an intent to cheat the vendor, this is a plain fraud, and made punishable as such by statutes in many of the states.'
