circumstances will permit. Large plants of Boronias will remain 

 healthy for several years without repotting, provided the drainage 

 keep in good working order, and they are properly attended to in 

 other ways. Good peat, such as a Heath-grower would select for his 

 favourites, and coarse river-sand, in the proportion of one-third in bulk 

 of the latter to two-thirds of the former, make a good mixture for 

 applying to the roots of Boronias ; and on all occasions when they 

 are repotted, the compost should be made as firm as possible about 

 the roots. In the matter of applying water to the roots, the cul- 

 tivator should exercise much care at all seasons, as an excess is very 

 prejudicial to their health ; and on the other hand, the soil must not 

 be allowed at any time to become what might be termed dry. Another 

 matter to be attended to in their culture is to keep them clear of mil- 

 dew. Some species, particularly B. serrulata, are subject to attacks of 

 mildew, and a strict watch should be kept for its appearance. If at 

 any time it is discovered on the plants, they should be laid on 

 their sides and dusted with flower of sulphur, which will have the 

 effect of arresting the further progress of the enemy. In addition 

 to the three species already named, B. crenulata and B. megastigma 

 are deserving of being cultivated by all lovers of choice greenhouse 

 plants. The latter, when in good health, is an elegant and graceful 

 plant when not in flower; and when in bloom it is surpassed by few 

 in the quiet beauty of its flowers. J. Hammond. 



THE ROSE -HOUSE AND POT-HOSES. 



^Iany are apt to overlook and neglect both Ptoses in pots and those 

 that are planted permanently in the Rose-house during the season 

 when they can be gathered in abundance outside. I have seen Roses 

 in pots that have done duty and bloomed, much neglected even when 

 the thought that outside Roses would be an uncertainty, or a fear enter- 

 tained by the majority that outsiders would be severely injured, if 

 not killed outright. Even when this state of things has been upper- 

 most in the minds of those most interested, Rose plants after blooming 

 have been carelessly treated and cast aside — either forgotten or left 

 to chance until wanted for forcing again, and have then proved almost 

 if not quite a failure. One would naturally think, when the outside 

 supply is likely to be somewhat limited, that greater care would have 

 been bestowed upon those in pots, which, if properly treated, would have 

 made a supply certain. There are those who have Rose-houses and 

 require them for early work, but keep them slowly moving for the 

 few flowers they produce ; and then, instead of treating them properly, 

 to force upon them a good rest, are what they call partially pruned back 

 and allowed to go on again. These, as I have before stated, soon 

 become a prey to mildew, and look unsightly. This system will not
