Conversation with my boss

Winter 1978- University of Tennessee

Gene: “My Dad wants to know what cotton variety he

should plant next year.”

Phillip Hoskinson: “Hmm…. Tell your father that will

depend on the weather. If I knew what the weather is going

to be, then I could tell him the best cotton variety to plant.”
