obvious that, by being potted a twelvemonth previously, they become 

 thoroughly established, and are better enabled to support an accelerated 

 growth and premature development of bloom." 



" Forcing-house. — A span-roofed house, with a longer roof toward 

 the south, is, perhaps, the best style of building. Heating by hot water, 

 in its various modes of application, is generally acknowledged to be 

 preferable to the old flue system, and in no instance is it more so than 

 for forcing Roses ; nevertheless they will flower well in houses heated 

 with flues. Arnott's stove, which is used by some, is found to answer 

 exceedingly well. 



" Every precaution should be taken against mildew. If the weather 

 be cloudy and wet, a brisk heat should be maintained, that we may not 

 have a cold damp atmosphere. The application of sulphur is a well- 

 known remedy, dusted on the leaves, while wet, from a dredging-box ; 

 and by admitting abundance of air, and at the same time applying fire- 

 heat, should the house be damp, to establish a free circulation among 

 the plants, its progress will certainly be arrested." 



" Ripening the Wood. — It is important, with regard to Roses in- 

 tended for forcing, that the wood be well ripened early in autumn ; and 

 to effect this end they should be placed in a sunny and airy situation 

 during summer, and should not have too free a supply of water when 

 completing their growth. So soon as they have done growing, the 

 shoots may be thinned out, the shortening-in of the shoots being de- 

 ferred till the plants are conveyed into the forcing-house." 



11 Housing the Plants. — It is advisable to keep the plants as close 

 to the glass as possible ; and if a gentle bottom-heat can be secured, so 

 much the better. When the buds begin to swell, the heat may be 

 steadily increased till we reach 60° to 80" by day, and the night tem- 

 perature should never be lower than 40° ; a difference of 15° or 20° 

 between the day and night temperature proving beneficial." 



" Watering. — During their growth the plants should be freely 

 watered ; occasionally with guano-water, about the temperature of the 

 house ; or, if worms work in the pots, lime-water is an efficient remedy." 



" Syringing. — In bright weather the plants should be freely syringed 

 morning and evening ; in dull weather very lightly, and once only ; 

 soot-water may be used here with good effect." 



To obtain Roses late in the year Mr. Paul selects the autumnal class, 

 pinches off all early-shown buds, but after the first of September allows 

 all that appear to remain, and by which process he has gathered many 

 beautiful Roses on Christmas-day. The varieties he recommends " are 

 such kinds as produce a great quantity of flowers, and open freely.

This is an admirable little neat publication, containing much that is 

 highly interesting and useful, and those of our readers who have to
