174 FRUIT CULTURE UNDER GLASS. 



The trees should be dry the evening of fumigation, and 

 the tobacco should never be allowed to burst into 

 flame. The fumigation should not take place when the 

 trees are in bloom. 



Brmm-Scale. — I never had to deal with this insect 

 on peach-trees biit once. The trees were syringed, after 

 they dropped their leaves, with water at 145° ; and 

 though the wood was coated with the insect, I never 

 saw more of it after the syringing. 



Thrips. — This is a troublesome enemy to peaches 

 when it attacks them. It cannot be said that the 

 peach is subject to thrips ; but when plants infested 

 with them are placed in peach-houses — which never 

 should be, but often is — they spread rapidly on the 

 peach-foliage. Fumigation with tobacco, on which 

 some Cayenne pepper has been dusted, for a few suc- 

 cessive nights, destroys it. Engine the trees freely 

 after the fumigations to wash the insects and the smell 

 away. When the fruit are gathered, thrips can be con- 

 quered by syringing two or three times with tobacco- 

 liquor, made by boiling at the rate of 3 oz. of tobacco 

 to a gallon of water. This should be applied late in the 

 evening, and the house kept close for the night, so that 

 the liquor may hang longer about the foliage. 



DISEASES. 



The peach and nectarine are singularly free from 

 disease under glass in a good border, unless it be mildew 

 at times on some varieties. They are rarely attacked 

 with those diseases, such as curl and canker, which are 

 so troublesome on the open walls. Gumming occasionally 

 causes the death of a branch, and is often the result
