  Nos. 10498, 10499.
  United States Court of Appeals Sixth Circuit.
  Oct. 12, 1948.
  Don C. Miller, Francis B. Kavanagh, and Johnson, Branand & Jaeger, all of Cleveland, Ohio, and Thos F. McGovern, of Washington, D. C., for appellants.
  Leckie, McCreary, Schlitz & Hinslea, of Cleveland, Ohio, for appellee.
  Before ALLEN, MARTIN, and MILLER, Circuit Judges.
  PER CURIAM.
  This cause came on to be heard on the record and on the briefs and oral arguments of attorneys for the contending parties; and it appearing that the findings of fact of the district court are based upon substantial evidence from which are drawn correct conclusions of law and that neither the findings nor conclusions are clearly erroneous and that the reasoning of the district court in its opinion is logical and sound, the decree 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.
