Settles appeals his conviction for possession with intent to distribute 288 pounds of marijuana. He contends that border patrol agents have no authority to search for drugs, that the evidence against him obtained by such a search should have been excluded, and that statements he made after he was given Miranda1 warnings should have been excluded at trial. We affirm his conviction.

Border patrol agents in Laredo, Texas, observed brick-shaped objects inside burlap bags in the back of the pickup truck Settles was driving. They questioned Settles, inspected the burlap bags, found marijuana, arrested Settles, and gave him Miranda warnings. He then told them that he had purchased the approximately 300 pounds of marijuana contained in the burlap bags.

Settles' argument that the border patrol agents had no authority to search for drugs was disposed of in United States v. Thompson, 5 Cir., 1973, 475 F.2d 1359. There we explained that "[b]y a series of proper delegations, border patrol officers have been designated by the Treasury Secretary as customs agents." After setting forth those regulations, we continued:

By letter/order of the Assistant Commissioner of the Bureau of Customs, dated July 14, 1971, all special agents were required to designate all current border patrol officers and future appointees as acting customs patrol officers.

This Court has often recognized that a border patrol officer may be validly authorized to act simultaneously as a customs agent.

475 F.2d at 1362. See generally United States v. Wright, 5 Cir., 1973, 476 F.2d 1027; United States v. McDaniel, 5 Cir., 1972, 463 F.2d 129; United States v. Bird, 5 Cir., 1972, 456 F.2d 1023; United States v. Maggard, 5 Cir., 1971, 451 F.2d 502.

Border patrol agents are authorized to act as customs agents; thus, the officers here clearly acted within their authority. The district judge did not consider that their action constituted a search of the vehicle; rather, he reasoned that the officers saw what they believed to be the commission of a felony-the transportation of contraband-and acted to prevent further violation of the law. We hold that under the circumstances the border patrol agents' action was reasonable and the evidence they obtained was admissible at trial.

As counsel for the appellant says, the Miranda decision "speaks for itself." Consequently, his allegation that Settles' post-Miranda statements should have been excluded escapes our comprehension.

Affirmed.
