. Trial commenced on April 16, 1973, and the record was closed on May 24, 1973, after 29 days devoted to the taking of evidence. The expedition of the case consistent with full, fair and vigorous presentations was due in important measure to the ability, organizational talent, diligence and experience of counsel, together with the routine informal conferences held each morning before the convening of court among court and counsel where evidentiary problems were anticipated, presented and explored and the management of proceedings was otherwise charted from day to day. A brief post-trial conference was held on May 25, 1973. The parties submitted their separate proposed findings of fact and conclusions of law in compliance with the request of the court, and on June 18 and 19, 1973, oral arguments were had. Whereupon the case was submitted for decision and by the court was taken under advisement. On September 17, 1973, findings of fact, conclusions of law and judgment and decree were filed. On October 16-18, 1973, timely postjudgment motions for correction and amendment thereof were argued to the court and submitted for decision on supplemental briefs.
