strong sunshine. Keep them and Oranges free from scale, itc. " Win- 

 ter-flowering Heaths, Epacris, Oranges, Cytisus, Acacias, and other 

 winter-flowering plants, should be hardened gradually, when they have 

 made plenty of growth. They require abundance of water and free 

 drainage. Plants in pots are all the better if they can be tilted up to 

 throw off heavy rains. Achimenes, Gloxinias, Gesnerias, Eucharis 

 Amazonica, Poinsettias, and a host of similar things, can be grown on 

 in frames or pits during this season. Plenty of tepid water at their 

 roots, shifting to larger pots as they require it, turning round to the 

 light, syringing and shutting up early with sun-heat, airing judiciously, 

 and shading from sun, are their chief requirements. Turfy loam, peat, 

 and sand will grow these well. All stove-plants require shading more 

 or less. M. T. 



RUST ON GRAPES. 



In his Treatise on the Grape Vine, Mr W. Thomson giv^es it as his opinion that 

 rust on Grapes is caused by sulphur coming in contact with the fruit at a very 

 early stage of its development. Rust has been ascribed to many causes, and 

 the above statement was at first received with some little hesitation. We beg 

 to state a few facts which show that rust is caused by sulphur. In an old 

 house where the Vines had of late years been neglected — a prey to mildew and 

 other ills — an effort was last winter made to get these Vines into a more satis- 

 factory state. Vines, house, and everything, were thoroughly cleansed, and by- 

 and-by the Vines were gently moved on by a little fire-heat. The house is 

 heated by an old-fashioned Ijrick. flue, which gets rather hot at the end adjoining 

 the furnace. The first Vine just over this hot flue broke first ; its Grapes were 

 in flower while the rest were only just showing. At this stage, the weather 

 being dull and cold, mildew was suspected, and sulphm- was used both on the 

 foliage and on the flue. The Grapes on the early Vine are now brown with 

 rust, while not a speck shows where the bunches were not developed at the time 

 of its application ; but those in bloom and coming in bloom have suffered much, 

 and prove the opinion above quoted to be correct. S. X. 



IlayU, 1873. 



[Those who doubt that rust is caused by sulphur-fumes should coat their 

 pipes with sulphur, and heat them well when the Grapes are youngs and they 

 will doubt it no longer. — Ed.] 



NOTES OW PROPAGATION 



Propagation", as applied to the vegetable world, may be defined as 

 the art of multiplying the many and various plants cultivated in our 

 gardens, either for their use or beauty. It is a subject well worth the 

 attention of all, more especially the rising generation of young garden- 

 ers, for whom these few remarks are specially intended. I am aware 

 there are many who attempt to set down young gardeners as a set of
