Remembered with fondness.
Jim supervised two trials I undertook for him in my first year as a Horticulture Advisory Officer in Hastings as an extension officer with the then Dept of Agriculture  
One day I will  locate two photos of them . One with Jim. To do with two fungus: Sclerotinia diseases. Of dwarf tomatoes and golden queen peaches, economically important crops on the Heretaunga plains  then.
