is, I think, the best way of doing so. Later on, when you do not have the 

 hot-water pipes in use so much, you can dust the plants with sulphur 

 and keep it under ; but it disfigures the foliage, and is not, I think, so 

 effectual as the former method. Green fly can be easily killed under 

 glass by fumigating with X L All or a similar compound. Red spider 

 does not trouble you much in winter, but it is very troublesome at times 

 in the summer months, and then the remedy is well syringing every day 

 till you get the pest under. 



Perhaps you will like to know the varieties which I think do best, and 

 which I grow in quantity for early forcing. H.-P.'s and H.-T.'s are : 'Mrs. 

 John Laing,' ' La France,' ' Captain Hayward,' ' Mrs. S. Crawford,' 1 Ulrich 

 Brunner,' 'Baroness Rothschild,' 'General Jacqueminot, ' Mdme. Montet,' 

 'Caroline Testout,' ' Mrs. W. J. Grant.' Teas : ' C. Mermet,' ' Niphetos,' 

 ' Anna Olivier,' 'The Bride,' ' Perle des Jardins,' 'Bridesmaid.' 



Now I must say a few words about planted-out Roses, and the best 

 kind of house to grow them in. I grow them in both lean-to and span- 

 roof houses, but I like the span-roof house better. The houses I prefer 

 are span-roofs twenty feet wide with a sunk path on each side, which leaves 

 two side borders four feet wide, and a centre^bed eight feet wide, and then 

 you can plant such a house with Roses permanently, or if in pots you can use 

 it for Tomatos and Chrysanthemums after the Roses are taken out. When 

 planting I put the plants about eighteen inches or two feet apart, so as to 

 cover the ground soon. When established, prune them about the first 

 week in January, give them manure and a good soaking of water, shut the 

 house up close to make them break well, and then cultivate them as 

 described for pot Roses till the first blooms come ; as soon as they are over, 

 the plants (being Teas or Hybrid Teas) soon make their second growth, 

 and on some varieties you get finer blooms off the second growth than 

 you do off the first, especially ' C. Mermet.' After the second blooms are 

 over in June or July, and there are plenty of Roses out-doors, it is well to 

 give them a little rest, which you can do by withholding water for a time, 

 and then you can get some nice blooms in the autumn before the winter 

 comes in.
