¶1Robert C. Walker, pro se.
¶2Theodore E. Smith, Asst. U. S. Atty., Atlanta, Ga., for appellee.
¶3Before COLEMAN and SIMPSON, Circuit Judges, and DAWKINS, District Judge.
¶5By habeas corpus, this appellant challenged the duration of his sentence. The District Court denied relief. Before the case could be calendared and heard here the sentence expired. The case, therefore, is moot.
¶6Appeal dismissed.
