Mr. W. J. Leitch, Warden Place, Forres, N.B. , who sent us the photograph from which the engraving was taken, sends us the following particulars about the plant: I send you a photograph of a Clematis (Duchess of Edinburgh) I have growing on the wall of my house, and which, I think, being grown so far north has done fairly well. The plant is five years old, and has been four years in its present situation, exposure south by west. It bore altogether seventy blooms, and the colour was beautiful. The photograph was taken on June 18, and on June 28 there were sixty-two blooms full out. Last year it bore fifty blooms, but flowered a month earlier; the first bloom was full out on May 20. It had no protection during the last winter, and was only covered for a few nights during the frosty east winds we had in March last.
