Appellant, found guilty of smuggling seventeen pounds of marijuana in violation of 21 U.S.C. § 176a, raises but one ground of alleged error on this appeal— namely: that the Assistant United States Attorney used prejudicial and inflammatory arguments to the jury. No objection was made to any of the twelve matters now charged to constitute error. Under the court’s cautionary instructions to the jury, we hold there was no error. The judgment of conviction is affirmed.
