 when subjected to a 

 high temperature

Red Spider

 — Unless on dry 

 sites or soils, or 

 in exceptionally hot 

 seasons, this sel- 

 dom seriously in- Pig- 54.- 

 jures Koses in the 

 open air. It fre- 

 quently, however, infests them on south walls, and 

 especially if the borders are dry. Koot-soakings 

 and overhead deluging are the best antidotes against 

 Red Spider; persistent dusting with sulphur, first 

 damping the surface to make it stick, will also 

 speedily either suffocate or poison this small but 

 destructive insect. Unfortunately it generally accu- 

 mulates most thickly under the leaves, where there 

 is most difficulty in reaching it or ,keeping it 

 smothered with sulphur-dust, or wet through. Thus

 from such friends! 

 Ants are not only a 

 real pest, not to say 

 danger, among- 

 Koses, but they 

 help, not hinder, 

 the enemy to the 

 utmost of their ca- 

 pacity. The popular 

 fallacy that they 

 kiU and eat Aphides 

 has long been ex- 

 ploded. On the con- 

 trary, they find them 

 legs until the 

 winged ones appear, 

 which can very weU. 

 dispense with the 

 Ants as carriers. 

 The Ants make a 

 thoroughfare of our 

 Rose - trees, form 

 nests among the- 

 roots, worry the 

 bole, eat the Rose- 

 blooms, convert our 

 best blooms into- 

 drawing - room, 

 lounges, and not 

 seldom startle or 

 sting our fair sisters 

 while they are luxuriating among the Roses. Away 

 with them from Rose-trees ! Allure them with sugar 

 and honey, or disgust them to a distance with 

 guano and sulphur dressings, dose them with weak 

 solutions of paraffin, and, when the distance i» 

 safe, scald them out root and branch with boiling 

 water. 



T%e Lady -bird {CoccinelUana septempunctata) is- 

 of quite a different character. This does not seem 

 to injure the Rose in any way, and it assuredly eat»
