THE FLORAL WORLD AND GARDEN GUIDE. 



ing Noisette and China roses should be 

 very moderately pruned, and climbing 

 roses should be simply slightly shortened 

 back and regula.ed, and occasionally an 

 old rod cut clean away. Now is the best 

 time in the whole year to turn small 

 roses out of pots into the open ground. 

 You cannot get " all kinds of roses from 

 a good rose-grower on their own roots," 

 because for the first few seasons of 

 multiplying a new rose, Manettis are 

 used almost exclusively for the sake of 

 quick growth. Roses on their own 

 roots should be pruned by the same 

 rules as the same varieties on other 

 roots. All the varieties of roses and all 

 the modes of growing them are treated 

 of at length in " The Eose Book," by 

 Mr. Hibberd, which can now be had 

 through any bookseller. — Q-. W. F. M. 

 — The use of a mulching material on 

 the borders of your rose-house, whether 

 stable manure, or cocoa-nut fibre refuse, 

 will be more likely to prevent than cause 

 mildew. If you do not mind the ap- 

 pearance of the manure use it by all 

 means ; as to the smell that will go off in 

 two or three days, and you might pre- 

 vent the unsightly appearance of the 

 manure laid on by a thin sifting of fine 

 earth over it. There is no mulching 

 material to equal cocoa-nut waste for 

 cleanliness, for preserving the roots in a 

 moist condition, and for resisting sud- 

 den changes of temperature, and it has 

 moreover a very agreeable appearance 

 to the eye. There is, however, so little 

 nourishment in it, that it should never 

 be used where a feeding material is re- 

 quired. Let us hear about your roses 

 by all mean- 1 . We prefer close netting 

 to shade a rose-house, as it is so little 

 shade roses require. Divide your double 

 primulas in August, choosing rainy 

 weather for the operation. 

 Camellias. — I have seven camellias which 

 two months ago looked as healthy as 

 possible, and most of them set well for 

 bloom, but now they look as if they had 

 been scalded. Will you tell me the 

 reason, and what had best be done with 

 them. I have all your books, and can- 

 not find in them anything about camel- 

 lias going off as mine have done. — W. S., 

 Norwood. [You cannot find anything 

 in our books about camellias going off 

 as yours have done ! It would be a dis- 

 grace to the fraternity of gardeners, 

 and to some extent discreditable to ama- 

 teurs, if it were often necessary to deal 

 with such a case as yours, for your 

 plants have, no doubt, been literally dried 

 up, and will probably perish unless they 



have more water. We may suppose too 

 that they are frequently shut close when 

 the sun shines fiercely, and have thus 

 been burnt. The only hope for you is 

 to keep what is left of them well mois- 

 tened with the syringe from day to day, 

 and on bright days several times a day, 

 and shaded from the fiercest rays of the 

 sun. When they have completed their 

 growth, set them out of doors entirely 

 till the end of September, and if they do 

 not set bloom-buds this year they will 

 perhaps regain their strength, which will 

 be something after such a season of 

 affliction.] 

 Vakious. — Polly*— There is no air cham- 

 ber under the tray of the Waltonian ; a 

 packing of flannel, or other non-con- 

 ducting material, would no doubt con- 

 tribute greatly to preserve an equable 

 temperature for a longer period than the 

 present method. The introduction of a 

 coiled flue pipe to cany the heat of the 

 flame through a greater extent of water 

 will probably have this effect, that there 

 •will be no heat to carry, the flame will 

 not burn. Should it prove otherwise, we 

 shall be glad to know from your experi- 

 ments, but we cannot give you one word 

 of encouragement, having a drstinct 

 recollection of our own candle experi- 

 ments, when it was often noticed a 

 direct and short exit for the heated air 

 was essential to keep the flame burning. 

 — S. 2?. Walters. — One of Musgrave's 

 smallest size slow combustion stoves 

 would answer admirably for your house, 

 15 feet long, with high back wall. The 

 pipe can be carried up through the roof 

 without any damage to the house ; it 

 only requires the removal of a square of 

 glass, and replacing it with a sheet of 

 zinc, cut to fit the flue pipe, and cemented 

 round with putty. Our Musgrave did 

 us such good service last winter that we 

 shall have another word to say about it 

 some day. For the present we can re- 

 commend a straight zinc or iron pipe ; 

 ours is in all 8 feet long, and the 

 draught is perfect. — A. B. — A panel 

 garden is sunk below the general level 

 of the ground, so that the flowers are 

 either seen from a higher level or you 

 have to descend a step or flight of steps 

 to reach them. The plant you inquire 

 about is Juniperus sabina. — S. H. G. — 

 Your pretty yellow spring flower is Doro- 

 nicum Mexicanum. — Mr. B., Upper 

 Norwood. — Thanks for the seeds.— T. 

 T. W. — We can only think of " Profit- 

 able Gardening " as likely to suit your 

 wants. There is really no such book in 

 existence as you inquire about.
