opinion: George O. BAIRD, Jr. v. Mark V. MARLOWE.
  No. 14279.
  United States Court of Appeals Sixth Circuit.
  April 21, 1961.
  Walter C. Cox, Jr., of Fowler, Rouse, Measle & Bell, Lexington, Ky., for appellant.
  B. L. Kessinger, Jr., of Harbison, Kessinger, Lisle & Bush, Lexington, Ky., for appellee, Nathan Elliott, Jr., Lexington, Ky., on the brief.
  Before MARTIN, CECIL and WEICK, Circuit Judges.
  PER CURIAM.
  This action for damages was brought by Baird against Marlowe for breach of contract relating to the operation of an oil-and-gas-lease business. There was a jury trial, at which the case was submitted to the jury upon interrogatories. These were answered by the jury favorably to the contention of the plaintiffappellee.
  The jury found that the appellee, Baird, had completed and performed the duties incumbent upon him as required by the contract. As a result of the jury’s findings, the United States District Court entered judgment in favor of the appellee for the total sum of $14,192.60, constituting $10,000 due for services rendered pursuant to the contract and the balance of the judgment being for interest and expenses.
  The court dismissed a counter-claim of the defendant Marlowe against plaintiff Baird.
  Upon review of the record, we find the answers of the jury to the interrogatories to be supported by substantial evidence; and that the trial judge, Honorable H. Church Ford, properly applied the pertinent law and committed no prejudicial error in the trial of the case.
  Accordingly, the judgment of the district court is affirmed.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "unclear". Your task is to determine what subcategory of business best describes this litigant.
