the winter season, and sprinkle coal ashes or lime scraps round 

 the outside of the bed. 



About the first week in March, I top-dress the plants by taking 

 away an inch of the surflice soil and substituting some rich com- 

 post. As soon as I can, I thin out the flower pips so as to leave 

 about six outside ones. By the end of April the plants are in 

 full flower. I then shade them from tlie sun to preseiTe the 

 colours uninjured. When the flowering season is over, I remove 

 the plants in pots to a suitable airy, shaded, situation in the gar- 

 den. When the plants are infested with green fly, I sprinkle 

 diluted tobacco water over them. If seed be desired, I gather it 

 when ripe, sow the following spring and raise them in hot bed 

 frame. As soon as the plants are up, I gradually hai'den them, 

 till they are strong enough to transplant into single pots, or into 

 the beds. AVlien tliey bloom, all pin eyes I cast away, retaining 

 only tlios^ that have fine yellow or golden edge, and strong gi'ound 

 colours. The finest sorts yet cultivated are Waterhouse's George 

 4th, Buck's George 4th, Haworth's William 4th, Stead's Tele- 

 graph, Cox's Regent, Nicholson's Bang Europe, Hufton's Lord 

 Brougham, Hufton's Lord John Russell, Hufton's Lord Grey, 

 Billing's Queen, Parke's Nelson, Turner's Emperor, CrowTishaw's 

 Invincible, Billington's Beauty of Over, and Fletcher's Defiance.
