Let us take National Emblem. How did our esteemed and worthy friend, McGredy—the big, genial, open-hearted Irishman—obtain that variety? Was it derived from a Tea like Comtesse de Caraman, Francis Dubreuil, or Princesse de Sagan? He alone knows. This much is certain—National Emblem is mildew-proof; it is the right type for immunity. It defies the spores of the disease; they can find no congenial resting place on its foliage, stems, or thorns.
