  (Circuit Court of Appeals, Fourth Circuit.
  June 11, 1926.)
  No. 2478.
  In Error to the District Court of the United States for the Western District of South Carolina, at Greenville.
  Dakyns B. Stover, Haynsworth & Haynsworth, and Stephen Nettles, all of Greenville, S. C., for plaintiffs in error.
  Dean, Cothran & Wyche, of Greenville, S. C., for defendant in error.
  PER CURIAM.
  Consent judgment filed. Cost to be paid by plaintiffs in error.
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 "construction". Your task is to determine what subcategory of business best describes this litigant.
choices: residential commercial or industrial other unclear
