*474On Petition to Rehear
Mr. Justice White.• We consider the petition to rehear as being a restatement of the excellent briefs and arguments in support thereof heretofore filed by counsel.
We have reviewed our opinion and the authorities cited and relied on for our conclusions set forth therein.
After thorough and earnest consideration of this matter for the third time, once when considering the petition for certiorari, secondly when preparing our opinion, and now finally, on the petition to rehear, we are firmly convinced of the correctness of our opinion as originally prepared and it would serve no useful purpose to repeat the reasons given to support it in this opinion on petition to rehear.
Therefore, the petition is denied.
