   PER CURIAM.

This is an appeal by plaintiffs [appellants] from a final judgment in favor of defendant [appellee] in a Federal Tort Claims Act proceeding. After an extensive trial, the trial judge entered findings of fact, conclusions of law, and judgment of dismissal on the merits.

On this appeal, appellant tells us that the basic question is “whether or not the appellants presented to the Trial Court a preponderance of evidence to prove that an agent of the appellee failed to act as a reasonable and prudent man, under all circumstances, with respect to a duty owed to the appellants; and whether or not the appellee’s conduct amounted to negligence as a matter of law and that such negligence was the proximate cause of the accident.” Appellants’ counsel earnestly contends that the answer should be in the affirmative.

Our examination of the record convinces us that the findings of the District Court were not “clearly erroneous.” There was conflicting evidence, it is true, but there was certainly adequate basis for the court’s findings.

Certain subsidiary grounds are urged for reversal, among them that the trial judge erred in not applying the “last clear chance” doctrine and also erred in denying appellants’ proffer and motion to amend the pre-trial statement.

We have examined all claimed errors and find no error affecting substantial rights.

Affirmed.
