104 ARRANGEMENT. [Mil/. 



yield nothing but disappointment to the anxiously expect- 

 ant cultivator. This disease is caused by an insect, Cymix 

 Chloroterus, or green bug. It inhabits the extremities of 

 the Dahlia, and grows and feeds on the under surface of 

 the young leaves, and in its destruction is aided by our 

 frequently hot and arid months of July and August. 

 Hence, the reason that the late planting gives most satis- 

 faction, they are in these months in a rapid growing state, 

 and if attacked outgrow the effects, and push at once into 

 bloom in the more moist and cooling month of September. 

 The only remedy that is known for the above evil is, to 

 look over the plants cautiously in the morning when the 

 first attacks are perceptible, and pick off the insect ; it has 

 to be approached with caution, as it instinctively throws 

 itself down among the leaves if disturbed ; -and if it escapes, 

 it again climbs up, and commences its depredations. It is 

 admitted that there are exceeding one thousand distinct 

 named varieties now in cultivation, and it may be desirable 

 to some that a select list of the choicest named sorts now in 

 cultivation should be given : but such is the almost endless 

 multiplicity of kinds, and such the numerous additions 

 every year made, that in a few years those I may mention 

 now as being fine, will then most probably be considered 

 wholly useless. However, for immediate profit and bene- 

 fit, I recommend the following: 



PURE WHITE. 



Antagonist, Lewisham Rival, 



Cheltenham dueen, Miss Percival, 



Lady Langston, Pride of Sussex, 



White Defiance, Virgin Queen. 



WHITE OR BLUSH, SHADED OR EDGED WITH PINK 

 OR RED. 



Beauty of Sussex, Countess of Pembroke, 



Exquisite, Beauty of Wakefield, 



Emma Noke, Favourite, 



Lady Antrobus, Lady St. Maur, 



Mrs. Rushton, Diana, 



Phenomenon, Queen of the Isles.
