692 FEDEEAL REPORTER. �and there was no reasonable cause for the delay in effacing and oblit- erating the stamp, then you ought to return a verdict of guilty, �The counsel for the defendant insisted that even if the jury should be fully satisfied that there was a violation of law, the defendant is not guilty, as the ofifenoe was committed by hia wife in his absence, and without his knowledge and consent. As a general rule, the hus- band ia not criminally liable for offenees committed by the wife in his absence, and without his consent or procurement. If he is pres- ent with his wife, and participates in the crime, he may be indicted. In most cases of felony, but not in misdemeanors, where the hus- band is actually or constructively present at the time of the commis- sion of a crime, the wife may be excused, although she participated, on the ground of the actual or presumed command and coercion of the husband compelling her to the commission of the crime.

It is, however, well settled that where a master, owing a certain duty to the public, entrusts its performance to a servant, he is responsible criminally for the failure of hia servant to discharge that duty, if the non-performance of such duty is a crime. �The wife in this case was the agent of her husband, and he is criminally responsible, if, without reasonable justification and excuse, she failed to perform the duty imposed upon him by the law. �There is some direct conflict between the testimony of the witnesses ��� �
