PER CURIAM. The application for writ of error is refused, no reversible error. Rule 483, Texas Rules of Civil Procedure. So that there may be no question as to the effect •of the foregoing order, we expressly approve the holding of the Court of Civil Appeals (381 S.W.2d 347) that the trial •court erred in refusing to permit full cross-examination of the witness, Joe Compton, concerning the award made by the board ■of special commissioners in condemnation of which he was a member.
