I attended meeting in the Tabernacle. P P Pratt addressed the People spoke upon drilling wheat cultivating less land & doing it better. He was followed by President Kimball who said what Brother Pratt had said was Gods truth evry word of it for all truth was gods truth some people cannot see the end of theire nose if they did they would know more. I believe men in their resurrected bodies eat or they would die I believe they eat as well as men in their mortal bodies.
