Lady Hume Campbell, while not immune from disease by any means, is much the most reliable sort grown today and will please you better than any other you could grow. Double violets want quite different treatment from singles. They should not be left out and ex- posed to any frost, but are better housed early in September. While sin- gles do best in a winter night tempera- ture of as near 40 degrees as possible, doubles should have 5 degrees more •heat. They flower longer than the doubles; it should be possible for you to pick until well into May. After the middle of March the night tempera- ture can be dropped 5 degrees. Abun- dant ventilation, and, if warm, some shading on the glass, will help to keep the houses cooler and help the flowers to hold their color. C. SEASONABLE NOTES. Pmaing Hardy Boses. "With the removal of the winter pro- tection some idea can be formed of the effects of the severe winter on roses. Even the hardiest of the hybrid per- petual class are killed back quite low, but where a close covering of mother earth has been drawn about the plants, sufficient green, plump wood will be left to prune back. Don't be in a hurry about doing the pruning, for even in April we get some frosts of sufficient severity to seriously cripple the young shoots on the eafiy pruned plants. The hybrid perpetuals, such as Frau Karl Druschki, Brunner, Mrs. John Laing, Mrs. Sharman Crawford, Reynolds Hole, General Jacqueminot, Magna Charta and others, give the strongest shoots and finest flowers if pruned back hard. Leave not over three or four eyes on the strongest shoots, and one or two on more moderate ones. Cut out all weak and dead wood entirely. You can prune more lightly and secure a slightly earlier crop of flowers on shorter stems, but when it comes timo for winter protection th^ disadvantages of this system present themselve
