Excerpts of the President's News Conference
I think the idea that I might go hunting in Kentucky arose from the fact that the bird dog that was given me in Superior I had Colonel Starling send down to a friend of his in Kentucky, who is a very fine trainer of dogs. I presume that all the hunting I will do in Kentucky will be done by proxy through this dog.
