ture, both in the sand and in the house, 

 In order to work off the batch in shorter 

 time but the time thus gained is lost 

 when the young stock is potted. The 

 cool6r handled stock after being potted 

 goes to work at once and soon makes up 

 for lost time, both in size of plant, 

 quality of foliage and general constitu- 

 tion. 



A careful examination of the condition 

 of the sand every morning before water- 

 ing is absolutely necessary, as the young 

 stock is very sensitive to overwatering 

 and cannot survive a drying out. Dur- 

 ing bright weather the bench should be 

 sprayed two or three times a day to 

 keep the foliage fresh and crisp, as the 

 moisture on the foliage is a great factor 

 in helping to produce a good and uni- 

 form strike. 



After twenty-eight or thirty days of 

 this kind of treatment the cuttings will 

 be showing a suflScient quantity of 

 roots to require potting. Ribes. 



EFFECTS OF SULPHUR. 



I had an accident in my houses of 

 Brides and Maids by sulphur gas. On ac- 

 count of the weather being so mild I 

 could not use sulphur on the pipes, as I 

 was firing with hot water, and could not 

 get the pipes hot enough to give any 

 fumes, so I have been bothered with mil- 

 dew more or less. So I had an oil stove 

 and would boil sulphur every morning. 

 Yesterday I spilled some on the stove and 

 it caught the pan. Now I would like to 

 know what I must do. I have already cut 

 them down to about twelve inches of the 

 soil. Will it pay me to keep the plants or 

 throw them out and plant with new 

 stock and can I expect any blooms by 

 the holidays t The roses were two-year- 

 old stock and in very good health.

These roses might eventually recover 



but the chances are that by the time 

 they did recover the season would be 



over* Sulphur applied in this manner, if 

 it does not kill, leaves the plants in such 

 a debilitated Condition that they are sel- 

 dom worth bothering with. 



I should advise throwing them out and 

 try to secure some strong plants of such 

 strong and rapid growing varieties as 

 Kaiserin and Chatenay. The prospects 

 for a' holiday cut, even from the best you 

 can procure, will, be poor, but by nurtur- 

 ing and encouraging them during the 

 dark weather thiey may produce a fair 

 cut during spring, and at Easter. 



It is safer to use the sulphur blower, 

 though it has to be done three times a 

 week, than to run any risks with sulphur 



in a s.tate of fusion.

ROSE LEAF-SPOT. 



My roses appeared healthy up to a 

 week ago, when numerous spots appeared 

 on some of the plants and on others they 

 turned yellow and are dropping, some 

 plants being dead. I send a sample of 

 the foliage. I notice a multitude of 

 small white insects in the soil. What 

 are they and what shall I do for this 

 house?. B. L. B. 



These roses are infested with the 

 fungus Cercospora rosteola, or rose leaf- 

 spot, a rather uncommon trouble and 

 not very diflScult to get rid of. 



This fungus manifests itself by pro- 

 ducing spots on the foliage very much 

 resembling glass burns. A careful exami- 

 nation of these spots will show that they 

 are covered with a very fine gray matter 

 and that the edges of the spots are en- 

 circled by a purple border which is con- 

 tinually increasing its area. 



By reason of its very quick action this
