page 391 note 1 These results were borne out by the further experience at station I during the same winter with over 200 wallflower plants and 60 violas, all well established plants, set out in the soil of the garden in which our experimental boxes were sunk. Of these plants not a single wallflower and only two violas survived the winter.
