48 FRUIT CULTURE UNDER GLASS. 



juices of the plants, rendering them very unsightly, and 

 weakening them with great rapidity. It increases with 

 amazing rapidity, and yields only to the most severe 

 and laborious treatment. I have known collections 

 which have soon been rendered all but useless through 

 the introduction of a single plant with a breed of this 

 scale in it. 



I am glad to say that I have been fortunate hitherto 

 to escape having anything to do with it, and have so far 

 the want of experience in destroying it. Many are the 

 remedies which have been recommended for its destruc- 

 tion ; while some have looked upon it with despair, and 

 have got rid of it only by getting a clean stock of 

 plants, after having destroyed the infected ones, and 

 thoroughly cleansed their pineries. 



Mr Tillery, of Welbeck Gardens, has written so con- 

 fidently of a remedy which he has adopted with success, 

 that I quote what he has published concerning it : "I 

 mixed equal quantities of the driest new soot and flower 

 of sulphur together, and syringed the plants with a fine 

 syringe, then dusted them above and below with a 

 common sulphur puff'. It was done in the dead time of 

 the year, and not. syringed off for three weeks. The 

 syringing washed the mixture into the axils of the 

 leaves and to the roots, and in the soil, where it acted 

 as an excellent stimulant when the plants began to 

 grow in the spring. Out of six pits so done, I could 

 not detect one insect alive at the summer shifting, nor 

 have I found any since." Of all the remedies that I 

 have known to be used and seen recommended, this 

 appears to me to be the simplest and most effectual. 

 Some recommend dipping the plants in clean water, 

 heated to 130° ; others speak confidently of soap-suds
