   After we got them stopped, we asked them to get out of the car, which they did. Carroll referred to me, and called me by the name of 'Fred,' just as soon as I got up to him. Raised up the back part of the roadster; didn't find any liquor there; then raised up the cushion; then I struck at the lazyback of the seat and it was hard. I then started to open it up, and I did tear the cushion some, and Carroll said, 'Don't tear the cushion; we have only got six cases in there;' and I took out two bottles and found out it was liquor
