OPINION
PER CURIAM:


1
The Appellants Reginald Gaither, Franklin Moyler, and Wendell Smith appeal their convictions and sentences arising from their involvement in an assault on a fellow inmate at the Lorton Reformatory.   Finding no reversible error, we affirm the Appellant's convictions and sentences.


2
On March 14, 1995, a disturbance occurred on the ballfield at the Occoquan Facility of the Lorton Reformatory.   Several inmates attacked and repeatedly struck inmate Andre Jackson with weight bars, bats, and bricks.   Correctional officers saw and responded to the attack.   During the attack on Jackson, correctional officer Frederick Montanya was struck by a brick thrown by an inmate at Jackson.   An investigation into the attack revealed that the Appellants were Jackson's assailants.   The Appellants were indicted and received a jury trial in the federal district court for the Eastern District of Virginia.   The jury found Gaither guilty of assault with a dangerous weapon with the intent to do bodily harm,1 Moyler guilty of assault2 and assault with a dangerous weapon,3 and Smith guilty of assault.4  The Appellants now appeal their convictions and sentences claiming various errors.


3
First, the Appellants contend that the district court was without subject-matter jurisdiction over the crimes committed at the Lorton Reformatory and the district court erred in taking judicial notice that the Lorton Reformatory was within the special maritime and territorial jurisdiction of the United States.   The Appellants' claim is without merit.   It is well settled that the United States District Court for the Eastern District of Virginia has original jurisdiction for crimes committed at the Lorton Reformatory.5  Additionally, we find that the district court properly took judicial notice that the Lorton Reformatory fell within the special maritime and territorial jurisdiction of the United States.   Lorton Reformatory's location was generally known in the Alexandria Division of the Eastern District of Virginia and verifiable from "sources whose accuracy cannot reasonably be questioned."6  Next, the district court did not err by failing to instruct the jury that they could disregard the judicially noticed fact that the Lorton Reformatory was within the special maritime and territorial jurisdiction of the United States.   When the adequacy of jury instructions was not challenged at trial, a showing of plain error is required.7  The Appellants fail to show that the court's failure to specifically instruct the jury that they could disregard judicially noticed facts seriously affected the fairness, integrity, or public reputation of the judicial proceedings and resulted in a miscarriage of justice.8


4
Finally, the Appellants challenge various evidentiary rulings by the trial court to admit, exclude, or limit certain witness testimony.   Specifically, the Appellants contend that the trial court's evidentiary rulings denied them the right to confront and effectively examine witnesses.   The Appellants' claims are without merit.   The Appellants were able to examine all witnesses regarding their perceptions and recollection of the attack on the ballfield, their custody and handling of physical evidence, their authorship of various reports related to the incident, and any known inconsistencies.   A trial court's evidentiary rulings are entitled to substantial deference,9 and a court has great discretion on limiting testimony that leads away from the main controversy.10  Further, the jurors were able to assess the various witnesses' testimony for bias, and witness credibility lies within the sole province of the jury and is not subject to appellate review.11  Consequently, we find no abuse of discretion by the district court.


5
Accordingly, we affirm the Appellants' convictions and sentences.   We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
