JANUARY.] GREEN-HOUSE CAMELLIA JAPON1CA. 23 



prove fatal ; as, from appearance, many have died by 

 it in our city. If it has reached a great extent, the 

 leaves are brownish, having the appearance of being 

 decayed, or scorched with the sun. In taking hold of 

 the leaf, it feels soft, and altogether seems to have lost 

 its nutritive substance; and, when the young foliage 

 expands, it becomes covered with dark brown spots, 

 and finally very much disfigured; and, when in this 

 state, it is attacked by red spider, and, ultimately, 

 death ensues. 



If any of the plants are affected as above described, 

 take a sponge, and wash every leaf minutely with soft 

 water, and syringe them with water three or four times 

 a week, which will clean them. All the young foliage 

 will be healthy, and that which has been affected will 

 fall off. However, prevention is better than cure; and 

 if the Camellias are properly syringed every evening 

 during summer, and once or twice a week during win- 

 ter, they will never be subject to the ravages of mildew 

 or of red spider. 



Tie up any of the flowers that are expanded to 

 stakes, in case of accident; and, in syringing, observe 

 not to let any water fall on the flowers, as it causes 

 premature decay, and change of colour. 



The mildew first appears like small particles of very 

 fine flour, around the under edge of the leaves, and 

 visible to the naked eye; so that, syringing, spong- 

 ing, &c. under the leaf is most requisite ; but, as the 

 mildew extends, both sides of the leaves are covered 

 with these white particles.
