On Motion for Rehearing.
Pending action upon appellants’ motion for rehearing, we certified the controlling question in this case to the Supreme Court. The answer of the Supreme Court has now been received by us, and, in conformity therewith, appellants’ motion for rehearing is overruled. See Griggs Canning Company v. Josey, Tex.Sup., 164 S.W.2d 835.
